Why is My AC Blowing Warm Air?

As we enter spring and get ready for the summer, the days when we look forward to air conditioning in the comfort of our own home is around the corner. But those who rely on their air conditioner are sometimes faced with an issue: an air conditioner that blows warm or maybe even hot air. 

This AC problem isn’t unheard of. Although very alarming, it’s quite possible that an AC might just bail on us in the middle of a scorching hot day. 

4 Reasons Why Your Air Conditioner Blows Warm – Or Even Hot- Air

There can be many reasons your AC is blowing warm air, but here are the top four most common reasons you can focus on:

1. Air Filters Are Clogged

The air filters on your AC system are to trap pathogens and particles in the air. Still, they might become saturated over time as they work diligently to keep your air clean and safe to breathe. If your AC has filters that have become clogged, it can restrict airflow and lower air circulation. This clogging can also be the reason your system overworks, leading to other problems with your AC.

You need to change the air filters of an air conditioner every 30 to 90 days. The lifespan of your AC’s filter depends on several factors. These may include the number of pets you have, how many residents have allergies, and the number of smokers that use the space. Such factors will dictate how hard your AC will have to work, along with the amount of impurities and particles in the air that your AC filter needs to deal with. Another major factor is the square footage of your home. The bigger the space, the higher the demand on your AC.

2. Outdoor AC Unit is Blocked Up

Have you ever filled your refrigerator to the brim that you didn’t realize something obstructed it from circulating cold air? Just like your refrigerator, your AC also needs this freedom and space to work properly.

Air conditioners with obstructed or clogged outdoor units may overheat. If you don’t tend to your overgrown landscaping, or place the AC unit in a location that might cause it to be clogged by other debris, your air conditioner might start blowing warm air.

3. Compressor is Malfunctioning

Your air conditioner’s refrigerant should be able to cycle through your AC unit to blow cold air when it’s on. If there is a malfunctioning issue with the compressor, the refrigerant will not be able to find its way to turn from gas to a liquid so that it can cool your air.

Your AC might be blowing warm air because of a malfunction with its compressor. A properly-working compressor is crucial in an AC unit, as it is the part that’s responsible for making sure your AC vents are blowing out cold air.

4. Power Issues With Your AC

In addition to all the technical issues with your AC, another reason it’s blowing warm air might be that there are electric issues. Are you sure it’s wired properly and power reaches it without any issues? If not, that might be the reason for an AC blowing warm air.

Tripped breakers and blown fuses are also reasons for an AC not doing its job. These protect your air conditioner from possible electrical surges. If there is anything wrong with your fuses or breakers, you might be in dire need of help to solve a problem, and can cause your AC to blow hot air.
