Air conditioners can have a wide array of problems. One of the most common ones is that they seem to be working, they’re running, but it’s not cooling the house! This can be frustrating, especially during the hot summer months.
Depending on when you see the issue, and how it manifests, it could be one of several different issues. Let’s go over how you can tell what’s causing it.
What Causes Air Conditioners To Stop Cooling The House?
Air Filter Problems
If you see your AC unit is running all the time without cooling the home, the first thing you should do is look at the air filter. This is the easiest problem to solve, and doing so doesn’t require hiring an HVAC technician.
Clogged air filters cause poor airflow. Poor airflow makes it hard, and sometimes impossible, to remove excess moisture from the air. It also causes problems with the air conditioner itself. A clogged air filter could prevent air from reaching the coils in your AC unit, making it hard to remove humidity. The end result is a less efficient air conditioner that blows warm air.
You may also be using the wrong air filter for your HVAC system. Make sure to use air filters with a MERV rating that matches the recommended rating for your system.
