It’s summer in Houston, and you’re absolutely drenched in sweat from the heat and humidity. Right now, the thought of returning home to a nice, cool AC sounds divine. However, when you get home, you turn on your AC, and the air is warm. You are understandably confused and irritated about why your AC isn’t cooling. Luckily, you can read this blog to find out five potential reasons why your AC isn’t cooling.

5 Reasons Why Your AC Isn’t Cooling

If you keep reading this blog, you will learn five reasons why your AC isn’t cooling. Knowing these reasons will allow you to know how to properly troubleshoot your AC and return it to working order.

1. Incorrect Thermostat Settings

One reason why your AC isn’t cooling could be incorrect thermostat settings. If you’re dealing with an AC that fails to produce cool air, the first thing you want to check is your thermostat. For assistance, locate the user manual, as it will usually offer guidance on how to properly set it to cooling temperatures. Hopefully, a faulty thermostat is the only thing standing in the way of a cool AC.

2. Poor Insulation And Air Leaks

If the thermostat settings are in order and your AC still isn’t cooling, you might be dealing with air duct leaks. These leaks usually result from poor insulation material or insulation that is wearing away. When there are air leaks, a lot of the energy that would be used to cool or warm your home is lost, specifically 25-40% of it. If this is why your AC isn’t cooling, call an HVAC service to seal the leaks and properly insulate your HVAC system.

3. Dirty Condenser Coils

One part of your AC system, the condenser, is responsible for releasing heat outdoors from your home. This heat removal process happens when the air goes through the condenser coils. If these coils are dirty, the hot air is unable to leave your home. That’s why the next part of your home you want to check is the outdoor condenser unit to see if the coils are dirty. If surface-level cleaning doesn’t help, call a technician to see if the coils need unclogging.

4. Unclean AC Filters

You need to have clean AC filters in order to get the benefit of cool air in your home. In fact, experts recommend changing your AC filters every three months. If you’ve been neglecting this maintenance task, that might be why your AC isn’t cooling. Cleaning or changing your AC filters as soon as possible will hopefully return cool air to your home.

5. Worn Out AC

Finally, another reason why your AC might be lagging in effectiveness could be that it is nearing the end of its lifespan. If your AC has been around for more than a decade and it’s insufficiently cooling or warming your home, it might be time to replace it. When this happens, you want to call a professional HVAC service to help you find the right AC system to circulate air throughout your property.
