It’s 80 degrees outside and you decide that you can’t get away with leaving the air off any longer. You slowly get off the couch to go over to the thermostat to turn the air on and cool your home down. You set it to 75 and wait for that wonderful cold air to hit you in the face – instead, it starts to get warmer in your home. Frustrated, you turn the air off and decide to go seek air conditioning elsewhere. So, why could air conditioner be blowing hot air? Well, there are a few common reasons that your AC might be malfunctioning.
Common Air Conditioner Problems
- Your thermostat might be in heat mode rather than air – We know this sounds like a stupid reason, but people make mistakes all the time. It’s better if you can discover a human error on your own and make sure that there’s nothing wrong rather than call someone in and discover that you’re having problems simply because your HVAC unit was set on the wrong mode.
- The Freon/refrigerant may be low – This is a common problem when AC stops blowing cold air. If you don’t have a regular HVAC maintenance company, you may find that there isn’t enough Freon in the unit. It is also possible that your AC unit could be leaking Freon. If that’s the case, it’s advisable to contact a professional immediately, since Freon can be dangerous.
- Clogged air filter – Usually this won’t be a reason all on its own, but it can certainly contribute to warmer air blowing through your home (as well as increased energy bills). It’s important to make sure that you’re keeping the filter as well as the condensing coils free of too much dust and debris. Filters are fairly easy to change and inexpensive.
- The condenser or compressor could need cleaned – First, check the power supply to the part of the unit that sits outdoors and make sure that it’s switched on and functioning properly. Second, see if there are any air flow restrictions to the condenser coils. Keeping them clean is important for good, cold air flow.
