That's right. The weather is warm up and your air conditioning is acting up. What can you do?

This quick guide may help you with some of the answers.

Why Is My Air Conditioner Leaking?

Chances are your unit may not be leaking at all. Without your heating and air conditioning unit is geothermal, there is no water in your air conditioning unit. The fluid that cools and warms your indoor unit is Freon. Freon is a compressed gas in liquid form and when it is not pressurized, expands to its gaseous state at normal atmospheric pressures.

What does that mean? It means that the only fluid involved in the heating and cooling process turns to a gas when there is a leak.

That still does not help?

Fret not. What may seem as an expensive repair is just proof of a working air conditioning unit. What you see is the condensation from the coils. The coils pull moisture out of the air and drains it outside of your home. If you see water draining anywhere else but the outside of the home, you have a blockage or another problem and you need to call an HVAC contractor.

Why Is My Air Conditioner Blowing Hot Air?

First things first, it may seem obvious, but you would not believe how many service calls can be saved by checking this first. Is the thermostat set to “Heat” or “Cool?” If it is set to “heat,” there's your answer right there. Flip that switch and enjoy the cool air.

Now, if that is not the case, go ahead and take a seat. Multiple things could cause your HVAC system to blow hot or warm air. Some of the possible reasons for the hot air could be:

  • No or Low Freon
  • Frozen Coils
  • Wiring Malfunction
  • Outdoor Fan Malfunction

All of these possibilities need technicians to come and look at your unit. We service and repair most models of major HVAC brands.

Why Is My Air Conditioner Freezing?

If you live in the South, then humidity is no stranger to you. When your air conditioner is working, the warmth is taken from the surrounding air. This rapid change in temperature causes any moisture to condense that is typically drained through a pipe to the outside of the house. This water is most likely what you are seeing freeze.

While you will need a certified technician to find the actual cause of the freezing, the answers can be as simple as: coolant, mechanics, or airflow.

If you coolant is low, then the coils are dropping below the freezing point and trapping all the moisture on the coils. If you have mechanical issues like a faulty metering device, your coolant may be condensing faster than it is evaporating, causing the moisture to freeze. If your airflow is not adequate (from a dirty filter or dirty coil), there is less heat to remove. When there is not enough heat to remove, this causes the refrigerant to drop below freezing.

If your A / C unit is freezing, it is best to call an HVAC company to check it out before it stops working on the day you need it most.
