House not Cooling?

We had a question come up today about a home that never seemed to cool off during the day, but would get comfortable in the evening. Couple of things come to mind here.

One possible reason is that the AC is undersized.  This can be figured out by having an HVAC company perform a Load Calculation (measurement of how much heat is gained in the summer & how much heat you loose in the winter from your home). There is special software that is used to help make this determination.  Another possibility is an under charged unit (not enough, or low, refrigerant).  HVAC companies have tools to measure if this is the case.  A Third potential cause of your home not cooling properly is infiltration air (accidential air that does not come from the conditioned space, like an hot attic or the outside).  An HVAC tech can measure the temperature of the air coming thru the AC Coil & determine if this is the case.

There are also other reasons that could cause your home not to cool properly, if you have any questions, give us a call 815-254-5127!
