Troubleshooting an Air Conditioner

Troubleshooting an Air Conditioner

If your air conditioning installation in Provo is not working the way it should, there could be a number of factors in play. Before you call your commercial HVAC company for repairs, see if you can fix the problem yourself. Here is a guide to troubleshooting an air conditioner.

Thermostat and Air Filter

When your air conditioner is generating hot rather than cold air, the issue could be as simple as flipping a switch on your thermostat. Take a look at your thermostat and check to see that it is set to cool and that it is programmed at a comfortable temperature. If your commercial air conditioning system is generating cool air but not with enough power to efficiently cool the space, the problem may have to do with the air filter. The air filter is a screen that can fill up with dust and must be cleaned or replaced in order to facilitate efficient cooling.


When your air conditioner is failing to adequately cool a designated space, the unit may be lacking in refrigerant. This could be due to a leak or an aging system that no longer works as well as it had in the past. Since commercial refrigeration is a delicate process, it is best to call your commercial air conditioning repair service to handle this problem.

Evaporator Coils and Cooling Motor

Sometimes smaller problems can lead to larger ones; dirty air filters and low levels of refrigerant may cause the icing of your evaporator coils, which can impair the performance of your air conditioner. In order for the refrigerant to be effectively cooled down, the outside unit must also be functioning. When the cooling motor burns out or otherwise malfunctions, the fan blades may stop rotating and cease to cool the condenser. Call your commercial air conditioning service if this occurs.

Air conditioning installations involve many working parts, and not all malfunctions warrant a call to the commercial HVAC services. Make sure that the thermostat is set to cool and that air filters are clean. Your levels of refrigerant should be adequate and your evaporator coils and cooling motor must be fully functioning.
