HVAC Control Systems Are An Important Component Of Any Building

HVAC control systems regulate the heating, ventilation, and air conditioning systems in your home or business. For many large businesses such as office buildings, manufacturing plants, and schools, the controls are usually located in three separate areas. 1) A main mechanical room holds the actual equipment, including chillers, boilers, hot water generators, pumps, etc. 2)…

HVAC control systems regulate the heating, ventilation, and air conditioning systems in your home or business. For many large businesses such as office buildings, manufacturing plants, and schools, the controls are usually located in three separate areas.

1) A main mechanical room holds the actual equipment, including chillers, boilers, hot water generators, pumps, etc.

2) The air handling units (AHUs) that distribute the air to the building may be in separate equipment rooms or on a rooftop.

3) Individual rooms may contain other equipment such as fans, exhausts, and temperature / humidity devices.

Manufacturing facilities and other large buildings benefit from HVAC control systems for three main reasons.

1) They help to maintain the comfort of the building, keeping it warm in the winter and cool in the summer. By regulating the temperature, employees are more comfortable and are likely to be more productive. Many products must be kept at room temperature, and equipment operates best when not in extreme conditions that could cause moisture or other issues.

2) They enhance indoor air quality. Comfort is not just dependent on the temperature in a building, but also on the quality of the air. A good system will not dry out the air too much, and it will not let the room become too arranged with humidity. Allowed a room to become too humid may cause issues such as mold. HVAC control systems should include features that address humidity as well as temperature.

3) They allow for reduced energy use. Because the equipment will only be activated at a predetermined temperature, humidity, or based on a schedule, a business can have some control over how often their HVAC control systems are in use. Instead of keeping the unit set on a specific temperature all the time, a company may choose to reduce the load by setting a different temperature for times when staff will not be in the building. Because the equipment will keep the temperature and humidity regulated, there will not be a surge in use because of an extreme temperature change due to the weather or other factors. Much of the equipment today is manufactured with energy savings in mind, allowing for credits from utility companies.

Whether you are remodeling a facility, building new office space, or constructing a new manufacturing plant, work with your architect and building planner to make sure you have the HVAC control systems appropriate for the size and function of your business.

An Overview of Pneumatic HVAC Controls

Heating, ventilating, and air conditioning systems require a setup that enables the user to determine the ambient temperature of the spaces within the building. To ensure the appropriate use of heating and cooling, controls must be efficient and easy to use. Pneumatic HVAC controls offer benefits for specific types of systems, but electronic heating and…

Heating, ventilating, and air conditioning systems require a setup that enables the user to determine the ambient temperature of the spaces within the building. To ensure the appropriate use of heating and cooling, controls must be efficient and easy to use. Pneumatic HVAC controls offer benefits for specific types of systems, but electronic heating and cooling can also be advantageous.

How It Works

This setup utilizes compressed air to set heating and cooling. Copper and plastic tubes make up the configuration, moving compressed air between the switch and a valve actuator located within the device. Thermostats and sensors within the unit are responsible for maintaining line pressure between the sensor and the valve actuator. As temperature and humidity vary, sensors respond accordingly to move the valve actuator, and the compressed air deliveries messages through the system.

Benefits

This design is inexpensive to install, use, and maintain. Pneumatic HVAC controls are also durable. It's common for work areas to be potentially hazardous. When a work area must remain free of electronic sparks, this setup is ideal because it is not electronic. It's also possible to use the structure at a reduced load such as 25, 50, or 75 percent, by setting the damper at a specific position, when desired. Electrical systems do not offer this variable. In addition, the compressed air used in this system is oil-free, clean, and dry.

Electrical Based DDC vs. Pneumatic HVAC Controls

Electrical based systems use an electronic signal to operate the heating and cooling mechanisms. With pneumatic HVAC controls, no electrical wiring is necessary to connect a thermostat with the device. Instead, air lines will be present through a building, supplying compressed air between an air compressor and thermostats. Additional air lines will also be present between thermostats and local control devices. The compressed air moving through these air lines makes this a nonelectrical option noisier than an electronic setup. Compressed air systems are also typically less reliable than electronic systems.

Converting to DDC

The conversion process to switch to an electrical scheme can be technically involved. Each thermostat present in the configuration will require the installation of wiring. This wiring may necessitate additional power circuitry to manage the electrical demands. Adding additional power sources could also necessitate extra transformers. It's possible to leave pneumatic actuators, or you can choose to replace them with electronic actuators.

It's also necessary to replace temperature, humidity, and pressure sensing devices to ones that will be compatible with the DDC controllers. It's not mandatory to replace existing valves or dampers, which can save on conversion expenses. Modules will need to be installed to operate HVAC components.

Because existing pneumatic HVAC controls can be dated, it may be necessary to tear out the existing air lines prior to installing the new electrical wiring. This process can be expensive and labor-intensive, so some people choose to avoid this process, if possible.

Assess your heating and cooling needs to determine which setup fits your needs and business operation for optimal comfort and energy usage.

How Many BTUs Does Your Air Conditioner Need?

When it comes to air conditioners, “the bigger, the better” simply does not apply. Many people think that investing in the unit with the highest level of BTUs is the smartest move. In reality, however, this is not the case. Before investing in a new AC, it is imperative that you calculate how many BTUs…

When it comes to air conditioners, “the bigger, the better” simply does not apply. Many people think that investing in the unit with the highest level of BTUs is the smartest move. In reality, however, this is not the case.

Before investing in a new AC, it is imperative that you calculate how many BTUs you need. Because one of the main functions of an air conditioner is to remove the humidity from the air, it is important to purchase a machine that is properly sized and will be able to remove the optimum amount of moisture. If the machine is too big, it will not do this efficiently. If the machine is too small, it will struggle to deal with the humidity in your home.

If you have a unit that is too big and powerful, it will not do a very good job in cooling your room. In particular, the machine will repeatedly turn on and then turn off. Because it will remove the humidity very quickly, the machine will shut down. But as soon as your room heats up again, it will turn back on. This is a bad situation because you will notice wild fluctuations in the humidity in your room and it will cost you dearly on your electricity bill.

Air conditioners are given cooling ratings in terms of BTUs. BTU measures the amount of heat removed from your room. The most common sizes of air conditioners are 5000, 8000, and 12,000 BTUs. To determine how many BTUs you need, you need to do a little bit of math.

To cool a room up to 250 ft.², a 6000 BTU unit will do just fine. For a larger room bike a 400 ft.² one and 8000 BTU machine is probably your best bet.

To determine how many BTUs you need, take measurements of the room where you plan to put the air conditioner. Many people like to have an air conditioner unit in their bedroom to keep them cool while they are sleeping. Some people also like the white noise of the units.

Often, families opt to put the air conditioner in the living room where the entire family can benefit from its cooling power.

Also, keep in mind that a window air conditioner or portable unit will cool only one room in your home. The air blowers on these units simply are powerful enough to force the cool air through your own home. If you need to cool multiple rooms, however, consider investing in multiple window or portable units and placing one in each room that you want to keep cool.

Air Conditioner Maintenance Tips For Everyone

Your air conditioner is one of the most expensive appliances in your home. Because of that, it is very important that you perform some regular maintenance on this machine. Taking good care of your air conditioner will ensure that it is running efficiently and that it will work for years to come. And because air conditioning repair bills can often be outrageously high, it is better to take some steps to prevent breakdowns from occurring.

Follow these tips for taking care of your air conditioner.

Tip 1:

Make sure that you check your unit's hoses at least two times per year. We recommend doing this in the spring and the fall. Take a close look to see if you can spot any leaks in the hoses. If you do see a leak in the hose, you can pick up an inexpensive leak repair kit from your local home improvement store. You want to make sure that you fix any leaks before they get bigger.

Tip 2:

Keep an eye on your compressor. The compressor is the outdoor unit for your air conditioner. You want to make sure that you clear out any leaves, dirt or debris from the top of the compressor. The compressor is the priciest part of the air conditioner unit. But since it is located outside, it often can get dirty. Make sure that you check it and clean off any debris once a month.

Tip 3:

Make sure you call and an HVAC specialist every other year. You should ask them to clean the ducts for your machine. This is a complicated job, so it's not for the do-it-yourselfer. But a highly recommended HVAC pro will be able to clean the ducts and make sure that the entire machine is still running well.

Tip 4:

During the winter months, make sure that you keep the compressor covered. You can pick up inexpensive air conditioner covers at your local home improvement store or through an online retailer. This will protect the compressor from snow and rain during the fall and winter seasons.

Some air conditioner installing companies will provide you with the cover when they install it the unit. If you do not have a cover or do not know where yours is, just pick up another one. They are fairly cheap, and they do a good job keeping your compressor protected.

Follow these easy tips to make sure that your air condition runs well for years to come.

Why You Should Consider Investing In Central Air Conditioning

There are many reasons why you should consider investing in central air conditioning for your home or multi-family housing unit. If you are looking for a way to keep a large home cool throughout the summer, central air conditioning is probably your best bet. While it can cost quite a bit to purchase and install…

There are many reasons why you should consider investing in central air conditioning for your home or multi-family housing unit. If you are looking for a way to keep a large home cool throughout the summer, central air conditioning is probably your best bet. While it can cost quite a bit to purchase and install the central unit, it will save you time and money over the long run.

In recent years, split systems have become increasingly popular. They are referred to as split systems because the evaporator is placed outside of your home and is connected to the air blower that is positioned inside of your home. The evaporator can be placed on the roof or adjent to your house.

The largest benefit of central air-conditioning is that the cool air is circulated through the entire building. Smaller window air conditioners, by contrast, only cool one individual room.

The other benefit of a central air conditioner is that you can set the thermostat to a certain temperature and it will continue to run until it detects that your home has reached that level of coolness.

Split air units are also very popular because they are fairly quiet. Because the loudest part of the machine (the evaporator) is located outside of your home, you will not be bothered by the humming of the air conditioner unit.

The split air-conditioning systems also do a great job cleaning the air in your home. As the air sucked into the air handler, it is forced through a filter and is cleaned and cooled before it is returned to your home.

Split air conditioners are also fairly easy to maintain. Because the evaporator is in one central area, HVAC experts can easily check on how well the unit is running. They also have easy access if repairs are required.

If you own an apartment building, we recommend going with a central system. It is far easier to deal with one central unit as opposed to dealing with each tenant's personal window air conditioner.

While many home or multi-family dwelling owners worry about the steep cost of purchasing and installing a central air conditioner, the investment does pay off over the long run. A central air conditioner will help you avoid the hassle of dealing with individual air conditioners in each room or unit. It will also allow the owner to decide on the cooling temperature.

When To Change Your Air Conditioner Filter

One of the best things you can do to extend the life of your air conditioner and keep it running efficiently is to do some regular maintenance on the unit. And one of the most important maintenance tips that we can give you is to change the filter of your air conditioner 2 to 3 times per year.

People often ask us how they will know when it is time to change their air-conditioner filter. This depends on a number of different factors. Here is an overview of the maintenance tips needed for the different types of filters.

Most central units rely on pleated filters. These are fairly efficient filters, running up to about 50% efficiency. If you use one of these pleated filters in your unit, you should replace it every 3 to 5 months. If you live and a particular dusty part of the country, however, make sure that you regularly change your filter every 2 to 3 months.

If you have a highly efficient filter, you will need to change it more often. The most efficient filters on the market today are the electrostatic, electronic, or HEPA filters. These are the most effective filters that you can find, but they do require that you change them more frequently than the pleated ones.

The electrostatic filters are probably your best bet for filter efficiency and saving money. When you first purchase electrostatic filter, you will pay quite a bit more than you would for pleated filter. Over the long run, however, the electrostatic ones are more cost-effective than the pleated filters. This is primarily because you can clean them and return them to the machine. We highly recommend the electrostatic filters.

With the electronic filters on the market today, they can get filled up with dust and dirt that they collect from your home. You can clean them and re-place them, but they are a bit of a hassle. To clean an electronic filter, requires a special HVAC cleaning solution, and you have to allow them to dry completely before you return them to the machine.

HEPA filters have become increasingly popular in recent years. These are the most efficient filters on the market. But because they are so efficient, they get clogged with dirt very quickly. This can have a negative impact on your air conditioner because a dirty filter will slow down the efficiency of your air conditioner. If you opt for HEPA filter, you will need to change it on a monthly basis.

Making Wet Area Ventilation Easy

The wet areas in a home are those supplied by water. They include a bathroom, toilet and laundry room. Each area has its zones. The dampest area in the home is the bathroom. Its zones are: Zone 1 – the area within a radius of 200 millimeters around the bathtub or shower. Vertically, it covers…

The wet areas in a home are those supplied by water. They include a bathroom, toilet and laundry room. Each area has its zones. The dampest area in the home is the bathroom. Its zones are:

Zone 1 – the area within a radius of 200 millimeters around the bathtub or shower. Vertically, it covers up to two and a half meters above the tub / shower floor.

Zone 2 – the area beyond zone 1 up to half a meter measuring horizontally. Vertically, it is still the area within two and a half meters above the shower floor.

Zone 3 – this is the driest of the three regions, starting from two and half meters beyond zone 2 horizontally and ends vertically at two and a half meters.

The fan needs to be positioned in a way that the moisture it draws from the air in the room is mostly from zone 1. That is when it will be considered effective.

Australian Standard AS3740 – “Waterproofing of Wet Areas within Residential Buildings' classifies the shower area as a high risk zone that must be ventilated well. .

The bathroom is a medium level risk area. Where there are timber floors, they must be waterproofed.

Heat recovery ventilation is the best way to go to ventilate your bathroom. When you use such system, not only is the moisture drawn from the bathroom, but also heat is supplied so the bathroom stays at a comfortable temperature.

There are brilliant solutions to adopting mechanical means to ventilate this part of the house. Over the years, quieter fans have been invented. They works so noiselessly you can almost forget they are in place. In addition to drying air, they dispel any odors and sharp scents so your bathroom stays fresh. There are 'smart' machines that have timers which can be reset. These estimate the length of time needed to shower and after you leave the room, automatically get to work.

The wettest areas are the most prone to mold growth and structural damage. Apart from the risks associated with mold, it is quite disgusting to use a slimy bath. This is part of the reason why wet area ventilation is a must.

As you may know, mold will cause your structures to collapse, the substances it produces will aggravate any allergies, especially of the respiratory system. They also cause hay fever. Worst of all, it may damage the nervous system. Who would look forward to showering in a permanently damp musty smelling bathroom anyway?

So why compromise? Get a fan fixed conveniently in your bath. If it is electrical, extra care is needed because it is easier to get electrocuted. Follow all guidelines when working with electrical appliances near water. Better yet, get the best supplier and fitter to position it out of reach. One brilliant safety measure is having a cord that starts the fan when folded instead of a switch. This way, no accidents can happen.

Why You Should Never Compromise On Whole House Ventilation

Every room in the home must be ventilated properly. Why so? The costs of poor ventilation are developing and aggravating respiratory infections, structural damage especially for timber, and inhaling permanently stale musty air. This is only at the surface. Neural damage by substances released by mold is a lethal threat according to Mold Factsheet Australia.…

Every room in the home must be ventilated properly. Why so? The costs of poor ventilation are developing and aggravating respiratory infections, structural damage especially for timber, and inhaling permanently stale musty air. This is only at the surface. Neural damage by substances released by mold is a lethal threat according to Mold Factsheet Australia.

Humidity is one element, just like temperature that must just be at a standard level. Too much of it and you'll be beildered by the wild growth of mold in all all corners of the home. Too little of it and you'll battling sore throats and itchy eyes all year round. With proper ventilation, you can keep these problems at bay. Natural ventilation may not be sufficient.It is scientifically proven that sometimes, opening windows causes energy loss. When the windows are wide open, the air will carry the heat away with it. Also, in busy and noisy places, natural ventilation may not be an option. You will most likely need mechanical devices that will work quickly, efficiently and quietly at the same time.

A proper ventilation will do four major things: it will balance the humidity in the house, let in fresh air while expelling the stale, cool the air during summer and heat it during winter. Standard number 62.2 of ASHRAE recommends a ventilation rate of 0.35 air changes per hour in homes. Australian Standard AS1668.2 for mechanical ventilation of homes requires the same.

Streaming windows are a sign of a problem with ventilation inside the home. That level of condensation is considered dangerous because it provides a conductive environment for mildew. This combined with heat is a recipe for disaster.

During winter when you need more heat, it may help to have dark paint on walls. They absorb and retain heat for longer. Air from rooms that are directly exposed to sunlight like attics is warmer most of the time. When distributed downward by fans, it warns the home further.

You can conserve energy by installing a Heat Recovery Ventilation System which balances the air in the room. It has fans that expel and propel air into the room while heating or cooling it at the same time. In the long run, it saves you money otherwise on the cooling or heating the home separately. It is one of the best ventilation systems available because it uses stale air to warm the incoming one.

Mechanical devices all have their devices. When choosing one, go for one whose speed is regulated. High powered fans can stir toxic lead or asbestos fibers. For health purposes, inspect your home regularly, especially areas that are not used frequently for structural damage. Dust and mop the home regularly to combat this.

You need economic yet effective whole house ventilation systems. You can find an amazing variety of options when you scout for them or find an excellent fitter. They will advise you, offer to visit and assess your home, recommend the best system, give you free quotations and after that, set it up.

Heat Recovery Ventilation Options For Your Home

Heat recovery is a ventilation system for the entire house that will both supply and extract air. Studies have suggested that it can recover up to 95 percent of heat which otherwise could have been lost through your standard home ventilation process. With a heat recovery unit centrally located in a loft or cupboard, each…

Heat recovery is a ventilation system for the entire house that will both supply and extract air. Studies have suggested that it can recover up to 95 percent of heat which otherwise could have been lost through your standard home ventilation process. With a heat recovery unit centrally located in a loft or cupboard, each of your rooms get connected through a network of ducts, wall or ceiling grilles.

How Do They Work?

HRVs comprise of two ventilation ducts that run next to each other. One duct rings in fresh air while the other one carries out the moist and stale air. The clever aspect of it all is that the two different airstreams go through a special device known as a heat exchanger which allows the air heading out to pass much of its heat onto the air that is getting in without the two streams of air really mixing together .

Heat Recovery Ventilation is appropriate for a newly built home. Your choice of a heat recovery unit bought to be based on a computation of your floor area and house occupancy levels.

A HRV is perfect if your home is located in areas that experience colder climates, because they experience excessive heating during heating season. The HRV unit gets rid of this excess heat. The upshot is that you receive a continuous fresh air supply, without experiencing any unpleasant drafts plus increased comfort within the home.

What Are The Advantages

In a paper which aim was to investigate the impact of HRVs on energy use published in 2003 on Management of Environmental Quality: An International Journal (Vol. 24), it was shown that the HRV system could lead to 74% energy savings. The paper concluded that using this system is fairly cost-effective and a worthy home investment. Other advantages include:

– HRVs give you a warm home that is well ventilated without having to keep on opening your windows.

– During the winter season, HRV could assist you in terms of savings on your home heating bills.

– During the summer, they lessen the need to have your air conditioning on most of the time.

– By keeping out excess moisture, they're best for your building structure, your furnishings, and for the health of the home occupants because they keep the internal climate a level that is constant.

– Typically they could retain much of the heat which would on average be lost from the home through standard ventilation. Some manufacturers put this at between 85-95% savings.

Are There Any Disadvantages?

– Most of the associated benefits can only be experienced if you live in extreme climates. In climates that are milder, the benefits are diminished and may be nonexistent in some cases.

– HRVs could be quite expensive to install. A typical HRV comes with several small electric powered fan blowers that cost some money to run.

– When using HRV in climates that are particularly cold, you'll require something more complex equipment to prevent the unit from freezing up.

– HRVs require regular maintenance. You'll need to clean or replace the filters every 6-12 months.

When you're planning for any ventilation system, there are several building code requirements which you need to observe. Specifically, the equipment must comply with the Building Code of Australia (BCA). The technician who is doing the installation for you must also comply with AS 1668.2 that address 'Mechanical ventilation for acceptable indoor air quality'.

Understanding Your Home Ventilation Options

All those impressive looking or sounding air quality control systems are actually of no use if your home lacks a good ventilation system to move the air each day. No matter what you install, you will be lacking a fresh and clean flow of air so long as your ventilation remains poor. A standard quality…

All those impressive looking or sounding air quality control systems are actually of no use if your home lacks a good ventilation system to move the air each day. No matter what you install, you will be lacking a fresh and clean flow of air so long as your ventilation remains poor.

A standard quality air filter will only remove larger particles in the air such as dust, pollen and dander. Even a good quality electronic air filter will only go further and get rid of smaller particles like gases, bacteria and mold. Neverless, since all these efforts, the quality of your indoor air may remain poor so long as no fresh supply of air is constantly coming in from outdoors.

Types Of Available Ventilators

Typically, the choice of ventilations systems available is limited. Your choice of a home ventilation system will greatly depend on both the quantity of air contaminants that your home has obtained and the amount of cooled or heated air which you are ready to lose daily through vents. In Australia, even in a room that has no ceiling fan, the Building Code of Australia (BCA) recommends that you bought to try and achieve a good level of effective cross ventilation.

– The Exhaust fan: This is the simplest ventilation method. A fan or multiple fans will blow out air from your home, in the process forming a negative air pressure zone within your house. Available air inlets will then let in new fresher air enter into your home and level out that pressure.

– Balanced Exhaust fans: Under this system, one fan blows your indoor air out while another fan pulls in fresh air. These are particularly vital if you are having gas burners or open flames, as it keeps the flames from getting snuffed out by the negative pressure.

These two traditional ventilation methods, while simple, are also quite inefficient. For example, in the mid of winter they will blow all of the heated air outside. In the summer, it will perform in a similar manner to the cooled air inside your home. Although, these methods will offer your home some degree of comfort, you certainly will be paying more for your energy consumption bill.

– Heat Recovery Ventilation (HRV): Because of the inefficiencies of the exhaust fans, the heat recovery ventilators are becoming very popular in most homes. Particularly if you have made the effort to have your home tightly sealed up to minimize loss of energy, these types of ventilation systems will save you lots of money.

When air gets ventilated via a recovery unit, the heat or energy gets transferred between outdoor and indoor air as it passes the unit. During the winter, the energy or heat in the indoor air gets retained while in the summer, the heat in your outdoor air gets eliminated before it makes its entry into your home.

Which Method Is Best For Me?

The technique you select will greatly depend on your present cost of cooling and plus what kinds of contaminants you're facing in the home. Another contributing factor would be the kind of building you want to ventilate and the kind of activity taking place inside.

If you decide to for the mechanical ventilation system, you'll require making sure that the unit plus its installation is in compliance with Australian Standards (AS) 3666.1 and AS 1668.2 dealing with 'Mechanical Ventilation for Acceptable Indoor Air Quality'. It is worth noting that the Australian Standard (AS) has been developed taking into consideration the ISO / DIS 16890 developed by the International Standards Organization.

Why Regular AC Maintenance Is Essential for the Health of Your Unit

There was a time, not so long ago, when an artificially cooled room was considered a luxury. When the first residential air conditioner was introduced in the 1930s, it was far too expensive for the average family to afford. But by the 1950s, with the growth of the middle class, millions of Americans were buying…

There was a time, not so long ago, when an artificially cooled room was considered a luxury. When the first residential air conditioner was introduced in the 1930s, it was far too expensive for the average family to afford. But by the 1950s, with the growth of the middle class, millions of Americans were buying AC units.

Where Are We Now?

Air conditioning is no longer seen as a luxury, but rather as a necessity. About 87 percent of American homes now have AC, according to a recent survey from the US Energy Information Administration (EIA). Most of these systems still rely on old technology, ie, window units, but central air is growing at a rapid rate.

What's The Difference?

Air conditioners that protrude from windows are not only louder and less efficient than central air systems, but they are also more expensive over the long haul. Yes, it costs a pretty penny to switch from window units to central systems, sometimes as much as $ 10,000. However, it may be worth the investment.

What's The Same?

Air conditioners are machines, and all machines require regular maintenance in order to function effectively. When regular service is not performed, window and central systems may break down or operate far less efficiently than they did when they were new.

The Benefits

No matter where you might stay, there's a good chance that you will be running your AC more during the summertime than in any other season. And like any machine, increased use increases the risk that the system or unit will malfunction or fail. When the thermometer spikes and air conditioners are running around the clock, repairs are almost inevitable unless your unit has been properly maintained. As they often say, an ounce of prevention is worth a pound of cure.

Better Cooling

All AC units take oxygen from the outside, cool it down, and pump it indoors. But when they do so, some of the pollutants, allergens, and other impurities must be removed. The filters that perform this simple but essential job will eventually get clogged. If they are not cleaned or replaced, the effectiveness and efficiency of your cooling system will suffer.

Whether window or central, your unit will require more energy to cool your home or apartment if the filters are obstructed, which will clearly increase your monthly utility bills. So it makes financial sense to have an AC professional clean or replace them when needed.

Longer Lifespan

If an air conditioner is clogged or there is some other issue, stress will be distributed throughout the system, and it may result in premature wear to vital parts and components. The damage that ensues may cause breakdowns and / or higher electricity bills.

Fewer Repairs

As you may expect, when vital parts are properly maintained, there's a much lower risk of failure. Simply changing inexpensive filters and getting regular service performed should be sufficient to prevent breakdowns.

Many people do not realize how many different airborne irritants can be slipping through the cracks and causing trouble in everyday life. Whether you own a business or simply are looking to keep your home free of these unhealthy irritants, air duct cleaning can be an extremely valuable service to get. Of course, not all air duct cleaning services are created equal, so prior to looking for companies in your area, it is important that you know exactly what to look for. When it comes to finding the best service around, here are a few factors to keep in mind.

1. Your HVAC System is a Safe Haven for Microbes

The average HVAC (heating, ventilation, and air conditioning) system is one of the prime locations for various microbes to replicate and call home, including mold, bacteria, fungus, and a variety of other contaminants. When your air is blowing, these airborne irritants are spread through your home or business, causing all sorts of issues in the long run and sometimes leading to immediate illness. This is especially true in months when your air might not run for days at a time, giving these microbes extra time to reproduce and spread.

2. Dirty HVAC Systems Waste Money

If your health is not motivation enough, another reason for you to seek out air duct cleaning is to save some extra money on your energy bill. A dirty HVAC system can cause inefficiencies in the unit, which leads to extra run time, which, in turn, ends up costing you more money out of your pocket. A good cleaning company can identify these issues to ensure you get the most efficient system possible. This will save your family plenty of money in the long run.

3. Tax Credits Are Available

In addition to saving you money on your energy bill, certain improvements can actually lead to federal tax credits. If you maintain a proper HVAC system, you could end up saving more on your taxes than you spent on the efforts to clean the air ducts. When searching for the best air duct cleaning service, it is important that you keep this in mind. Ask the representative if there are any tax credits that you might be able to work towards and save that extra money.

Ultimately, keeping a clean HVAC system saves money immediately through increasing energy efficiency and over the long term by cutting back on potential illness. It also ensures a smoother work environment and a more stable indoor temperature, both of which should be enough enough. When you are looking for the best air duct cleaning service, keep this in mind. It will not only save you money, but it will also save you the headache of trying to find the most qualified company.

Discover How to Keep Your Home Warm This Winter

On the other hand, your home may be staying warm, but you see your heat bills ballooning way over last year's rates. When you see this happening, a quick inspection of some of the more common areas from which homes can lose heat may yield some clues. Over time, the materials your home is built…

On the other hand, your home may be staying warm, but you see your heat bills ballooning way over last year's rates. When you see this happening, a quick inspection of some of the more common areas from which homes can lose heat may yield some clues.

Over time, the materials your home is built from can expand or contract. This often leaves gaps in your window insulation, gaps in the seals on your doors, or cracks and gaps in other areas around your home. Whatever the problem, you need to tackle it right away so you stay warm without energy flying out of your house and money flying out of your pocket.

Feel a Draft?

To begin, take an inventory of areas of your home where you may be losing heat. Pay close attention to the corners of the house as well as your windows, and doors. Rooms in which you rarely spend time also need to be examined closely. Look where appliances connect to the outside, such as the area around your dryer vent, incoming or outgoing pipes, as well as fireplace dampers and mail slots, if you have them.

If you find areas in which you feel a draft, note them. If you can possibly create a temporary way to block the draft from coming in, do so. For instance, you can block gaps under doors with a rug or close off little-used rooms that seem to be letting in drafts.

The Usual Culprits: Doors and Windows

If your doors and windows are older, they may not be very energy efficient. When you find one that is allowing drafts to come indoors, you may want to replace it with a “green” alternative. When you look for new doors and windows to replace your drafty ones, check your selections for their National Fenestration Rating Council (NFRC) rating. Although they may be more expensive now, the ones with the highest efficiency ratios to save money and energy over the long run.

You May Need More Insulation

If your windows are not insulated or if the insulation is old, you can easily replace the insulation. Inexperienced do-it-yourselfers can even find easy to install installation kits available at home improvement stores.

If It's Still Not Warm, You Might Be Due for a Home Heating Inspection

After you have eliminated all of the gaps and have installed energy-efficient windows, you may still find that your home is not staying as warm as it should be. If so, call your heating professional to inspect your home's heating system to see if it needs to be repaired. If you have not had your home's heating system checked for over a year, you need to make an appointment to have it inspected and tuned up for the winter months.

Your local HVAC experts have over 25 years of experience serving homes and businesses with their heating, ventilation, and air conditioning needs. If it's been a while since your home's heating system has been checked, contact an HVAC service company to schedule a service appointment.

Is It Time for a New Furnace?

Are you listening clanking or funny noises coming out of your furnace? Does it sound like it's dying a slow painful death? That may mean you it's time to invest in a new furnace. Do you know how old your furnace is? Is it 10 years old? 5 years old? Is it still under warranty?…

Are you listening clanking or funny noises coming out of your furnace? Does it sound like it's dying a slow painful death? That may mean you it's time to invest in a new furnace. Do you know how old your furnace is? Is it 10 years old? 5 years old? Is it still under warranty? Knowing the answers to those questions can help you make a more informed decision. Here are four warning signs that tell you it might be time to get a new furnace installed:

1) Do you know how old your furnace is? The average life span of a furnace is between 16-20 years. Some cheaper models only make it 10 years. Unsure of how old your furnace is? Look for a pilot light. Found one? That means it's well over 25 years old. Newer models do not have pilot lights. If your furnace is only 10 years old, invest in an appliance service plan – usually offered by your local utility company or heating and cooling company. It'll save you money in the long run and protect your investment. If your furnace is over 15 years, you may want to start saving money for a new furnace.

2) Have you noticed your heating bills going up year-over-year? That's a bad sign. Furnaces start losing their efficiency as they age. Make sure you get a yearly furnace tune up to make sure your furnace runs efficiency. If you've noticed your heating bill rising, contact your heating and cooling guy to have it looked at.

3) If you've had your furnace fixed in the last two years, consider the option that you may need a new furnace. Your furnace is like a car, the older it is, the more repairs you need. The more repairs you have, the more likely you are to need a new one.

4) How comfortable do you feel in your home? Are some rooms too hot while others are too cold? That's a sign that your furnace is on its way out because it lacks the ability to distribute air proportionately.

Now sit back and evaluate. Once you've evaluated the answers to the above questions, contact your neighborhood heating and cooling repair company. They can make an assessment for you based on what you tell them and by observing your furnace. If you think your furnace has another year or two left on it, start saving, then re-evaluate down the road.
