Why is My AC Running But Not Cooling?

Why is My AC Running But Not Cooling My House?

Here are some of the most common reasons why air conditioners run but don’t cool homes:

The Evaporator Coil is Frozen

Refrigerant Leaks

When an air conditioner has a refrigerant leak, it’s unable to perform properly. That means you’ll deal with ineffective cooling or even a system shutdown.

Inefficient Air Ducts

Not all homeowners are aware of how important the ductwork in their home can be for their indoor air comfort. Keep in mind that the ducts are the pathway for cool air to transfer throughout your home. If you have any leaks in your ducts, they become hugely inefficient and can lead to your air conditioner not cooling but running.

What to Do If Your Air Is on but Not Cooling

Alternatively, there are a few things you can do to troubleshoot the issue on your own. Here are two easy troubleshooting steps to implement if your AC is running but not cooling:

1. Double-Check Your Thermostat

Your thermostat settings might need adjusting. If your AC unit was recently serviced or if you live with people who may have changed it, then you may simply need to change it to “cool” and set it to your desired temperature.

2. Check Your Air Filter

The air filter collects dirt, dust, and other particles in the air to keep your air conditioner clean and running optimally. Once a filter is full of dirt, however, it can’t protect your air conditioner anymore and can end up worsening the debris infiltrating your unit.
