How does it feel when your AC is running but not cooling the house during the peak of summer? Many residents would feel frustrated when confronted with this situation, but getting angry will not solve the problem. The best option is to contact our technicians for professional Air Conditioning Installation in Alexandria, VA to help remedy this issue.

If your AC isn’t cooling the house, look out for the following reasons that are possibly causing the discomfort:

Leaking Refrigerant

Leakage of refrigerant could be one of the reasons your AC is not cooling your house. What do you know about refrigerants? It is a type of fluid present inside the copper coils in your AC system. The role of this fluid is to absorb heat from the air in the evaporator coil. Bear in mind that in order to work properly, each system must be filled with the required amount of refrigerant. If the refrigerant leaks out, it will negatively impact your AC system’s ability to cool the air.

It is important for you to detect the leakage of refrigerant and focus on repairing the leak rather than supplying more refrigerant to your AC system. Fixing problems with the leakage of refrigerant is not easy, so let our trained technicians do it for you.

Issues in Thermostat

If your AC is running but not cooling the house, there might be some technical issues with your thermostat settings. The reasons could be: someone changed the fan setting or temperature on the thermostat. Make sure it is set for cooling and not for “fan only.” If the problem persists despite the correct setting, you should switch over to the next step.

Frozen Evaporator Coil

Another reason for your AC not cooling your house could be a frozen evaporator coil, which happens when not enough air passes over the coil to prevent the liquid in the coil from freezing. Under this condition, you need to turn your AC off, and wait for a half-hour or so, allowing your system to run on “fan only,” until the coil is no longer frozen. If this fails to happen, call our technician.

Clogged or Dirty Filter

A clogged or dirty air filter could also be one of the reasons for your AC’s failure to cool your house. Under this condition, you should locate your air filter and inspect it visually. If you spot any debris or dirt, then change your air filter immediately.

Remember to change the air filter once every month. Doing this gives you not only cleaner air but also ensures the proper circulation of air in your AC system. On the contrary, if the air filter appears to be clean and still the AC does not cool your home, then you should move on to the next step.

Checking For Clogged Coils

Checking the outdoor coils is very easy. All you need to do is go outside and inspect the condenser visually. Check to see if there is any debris or shrubs close to the unit and whether the coils appear clogged with dirt, grass clippings, or other debris. If you find these obstructing things, wash the outside of the unit with a hose. However, if the problem does not go away, it is time to call our technician.
