Why Is My AC Running But Not Cooling?

Discover common reasons why your AC runs but doesn't cool effectively. Learn how to fix airflow issues, check filters, and more for optimal cooling.

Why Is My AC Running But Not Cooling?

There are a few reasons your AC unit might not be cooling your home as it should. If this happens, you should first check your air filter. A clogged or dirty air filter is the most common and straightforward fix.

Since the air filter is responsible for keeping dirt and debris out of the air conditioner, if it is dirty or clogged, it can restrict airflow and cause the air conditioner to run but not cool.

If your air filter is clean, then it’s likely a more significant issue like one of the following:

  • The air conditioner is not properly sized for the space it is trying to cool:
    Air conditioners need to have a certain amount of airflow over their evaporator coils in order to work properly, and if they are too small for the space they are trying to cool, they will not be able to provide enough airflow.

  • There is insufficient airflow over the evaporator coils:
    If there is not enough airflow, the coils will not be able to remove enough heat from the air, and the air conditioner will not be able to cool the space properly.

  • The refrigerant charge is low:
    When the refrigerant charge is low, there is not enough coolant in the system to remove the heat from the air, and the air conditioner will not be able to cool the space properly.

  • The condenser coils are dirty or obstructed:
    The condenser coils are responsible for dissipating heat, and if they are dirty or obstructed, they will not be able to do their job properly. As a result, the air conditioner will not be able to cool the space properly.

ACE was recommended to me by a friend when I was looking to have my system replaced. Everyone that I  dealt with, from Karl in the office to Fred and Mike, who installed our new system, was very professional and they went the extra mile to provide great customer service.  If you are looking for an HVAC company that is honest, reliable, and worth calling first , this is the one.

I can't express enough how much I appreciate ACE. They were so prompt with their responses and work. They did an absolutely amazing job with our two AC units. The customer service they provided was beyond what I am used to. I plan on being a lifelong customer of theirs. Feels great to have trustworthy people in this business especially since I am a first time homeowner and new to the area.

Great team. Provided honest feedback of the problem and took care of the issue. Company was recommended by my neighbor as a "trustworthy" business which is never easy to come by. Should the need arise I will only reach out to these guys.

I converted from total electric to gas in 2014 using ACE.  Eric could not have been more patient, informative, knowledgeable and helpful during the conversion.  I was very pleased with the work that was done.  Since that time i have used ACE's maintenance plan.  When I call the office to make my appointment, I am always treated as an individual and not just an address that has to be serviced.

Sharon M.

We have been using ACE for over 8 years and have always found them reliable, knowledgeable, reasonable and friendly. They have installed a/c units and a humidifier in our home and we also have a service contract with them. It is convenient and keeps our systems running smoothly. I would highly recommend them.
