Why is my AC running but not cooling?
This is a common problem during the summer months and is definitely cause for concern. Let's take a look at some things that may be going on so we can get your A/C working again. If you feel you are still not getting enough cooling from your AC, then it is probably a good idea to contact a licensed professional.
The following conditions need to be present in order for your system to cool properly:
1) The outdoor unit must have power. The outdoor unit must be receiving power from the breaker box.
2) The outdoor temperature must be above 55 degrees. Your air conditioning system will not cool below 55 degrees.
3) The condenser coil must be free of any obstructions. A dirty condenser coil will not allow the refrigerant to pass through and cool the air. The condenser coils are located on the back of the outdoor unit and are usually only accessible by taking off the front grill to expose the coils.
4) The evaporator coil must be free of any obstructions. The evaporator coils are located inside the home, usually in the attic or basement, and are the coils that actually remove the heat from the air.
5) The air filter must be clean. A dirty air filter will restrict the air flow and reduce the efficiency of the unit.
6) The thermostat must be set to the proper temperature. The thermostat is what tells the unit when to turn on and off.
7) The refrigerant levels must be adequate. If the levels are low, the system will not be able to cool properly. This is a condition that should be addressed by a licensed professional.
8) The ductwork must be free of any leaks or obstructions. Leaks in the ductwork will cause the cooled air to escape before it reaches the living areas. Obstructions in the ductwork will restrict the air flow and reduce the efficiency of the unit.
9) The outdoor unit must be level. If the outdoor unit is not level, the refrigerant will not flow properly and the system will not work properly. Checking these things will help you determine why your AC
