Why Is My Air Conditioner Blowing Warm Air?

Air conditioners are an essential part of enjoying the comfort of your home, especially in the sweltering summer months. That’s why the last thing you want to feel when you switch on your air conditioner on a hot day is a stream of warm air blowing in your face.

What do you do if your air conditioner malfunctions?

Here are some of the most common problems that would result in your air conditioner blowing hot air:

Incorrect settings. Sometimes human error can be the cause of your unfortunate air conditioning problem. It could be something as simple as having the selector switch accidentally set to “heat” instead of “cool”.

The condenser and compressor. If you feel confident that your setting are correct, the next step is inspecting the condenser and compressor. The first step is ensuring that the power is attached and switched on. If it’s off, the fans will blow air, but the compressor won’t actually cool it. The next step is to check if there are air flow restrictions, such as a build up of dirt or debris.

Refrigerant leak. The refrigerant that allows your air conditioning unit to cool the air can leak out for a number of reasons. This will result in your unit failing to function properly This problem should only be addressed by a professional HVAC technician, as the chemicals contained in the refrigerant are highly toxic.

Clogged filter. HVAC professionals recommend that you clean or replace your air filter at least once every 3-6 months. Over time, dirt can build up, significantly restricting air flow and compromising the cooling potential of your air conditioning unit. Additionally, excess dirt can emanate from your air filter and clog your condensing coils.

It’s recommended that you have your air conditioning unit regularly inspected and maintained by a professional. Attempting to repair your air conditioner without the proper knowledge, training, and experience  can result in causing further damage to your unit, as well as potential safety hazards.
