AC not cooling well
First i will begin by saying we live in Texas where it is HOT! Last week my AC unit was apparently hit by lightening and was fried. We had someone replace it with a 14 SEER Goodman unit. Our home is 1800sq feet. Although it is hot here (95 degrees) we never had a problem with our old unit which was also a 14 SEER but was a Braenurn (not sure about spelling).
This unit was just installed and already it has a hard time keeping up. We have the thermostat set to 72 yet it wont get cooler than 76 in here. We have not even hit the peak of summer so I am concerned. When I called the person who installed it, they said that AC units are made to cool to 20 degrees cooler than outdoor temperature.
Is this true?? Because that would mean once it hits 100, the indoor temp of my house wont get out of the 80's and I can't handle that!
