No one wants to come home to a hot house on a blistering, summer day. How come your AC isn’t blowing cool air when it’s still on? Here are some of the common issues behind that – and who to call if it happens to you.
Thermostat set incorrectly
First, check your thermostat status. If your AC is turned to “ON,” then your fan is going to run 24/7 – no matter the temperature outside. This will blow lukewarm air into your home, making it feel less cool than it should. To remedy this, change the status to “AUTO.” This will allow the thermostat to sense the temperature outside and adjust the indoor temperature accordingly.
Also, check to see where you have set the temperature. It may be a problem of someone changing the temperature to their liking while you were out.
If neither of these solutions do the trick, try temporarily setting the temperature to its lowest setting to see if your AC kicks on. Finally, make sure that your thermostat’s batteries have not died and that its wiring is still intact.
Dirty air filter
It’s easy for your air filter to get clogged by dirt, dust and debris. If you are not regularly cleaning your filter, your AC will have more trouble cooling your home. With a clogged filter comes restricted air flow. This makes it harder for your AC to push out cool air, blocking it from reaching the home – and causing you to feel hot and uncomfortable. If you avoid regularly changing out your filter, your AC will work much harder to do its job, and it can even cause a total system breakdown further down the road. Consider replacing your air filter every 1-2 months to avoid having to schedule a full AC repair.
Dirty or damaged compressor
Your compressor is located near your outdoor unit, where it collects branches, leaves and debris throughout the year. The branches and twigs can get caught in your compressor fan, causing damage and improper air flow. Make sure to regularly check your compressor to rid of the debris so that it can work properly. Sometimes, there are pieces of fallen foliage that you can’t get to or remove safely, so it’s best to call a trusted AC company to help you.
