Why Is My AC Not Cooling Properly?

A home’s HVAC system is made up of many parts either inside the house, making the air cool and fresh for you to enjoy living in it, or outside making sure your house gets plenty of cool air as well. These include all sorts of things from the AC compressor to the vents that blow out cooled air into your home. When any part of these is not working correctly at its best capability, problems can arise including a lack of cooling when you need it most. While oftentimes a problem with an HVAC unit may be obvious at first glance, sometimes there are quite a few possible reasons why your AC isn’t cooling properly, and does turning off your AC can help you resolve your AC problem? Here are some common reasons why your AC stopped cooling along with what you can do about them.

Common Reasons Why Your AC Stopped Cooling

1. Dirty air filter – A dirty air filter is the number one reason why an AC unit will not work properly. Not only does this block airflow and make it harder for the unit to do its job, but it also causes the unit to run for longer periods which can lead to early failure. Be sure to change your air filter every month or so, depending on how often you use your AC unit.
2. Clogged condenser – The outside part of your AC unit that sits in front of your house is called the condenser. This is where the heat from inside your house is released to the outside air. When this part becomes clogged with dirt, grass, leaves, or anything else, the AC unit will not be able to release the heat properly and will not be able to cool your home. Be sure to clean the condenser at least twice a year.
3. Leaky ducts – If your air conditioning unit is properly sized for your home but you’re still not getting the cooling power you expect, it may be due to leaky ducts. Leaky ducts allow cooled air to escape before it ever reaches your living space, causing your AC unit to work harder than necessary. Have your ducts inspected and sealed if they are found to be leaking.
4. Incorrect refrigerant level – A common problem with older AC units is that the refrigerant levels may be incorrect. This can lead to similar problems with the AC unit not working properly and not cooling your home as it should. Have an experienced technician come out and check for this problem.
5. Incorrect thermostat setting – It isn’t enough that you turn your thermostat up when you want your house cooled, but also make sure it is set at the right temperature for your home’s size.

Determining The Problem Why Your AC Is No Longer Cooling Properly

Now that you know some of the common reasons why your AC unit may not be cooling your home as it should, what do you do if you think one of these might be the problem? The best way to determine which one is the issue is to have a professional HVAC technician come out and take a look. They will be able to correctly diagnose the problem and provide you with the necessary solution. 

Oftentimes, it may not be just one issue causing your AC unit to not work properly, but a combination of several. So, it’s important to get them all fixed as soon as possible to start enjoying cool air again. Contact your local professionals for AC repair in Largo today for more information and assistance.
