Why isn’t my air conditioner cooling?
September 12th, 2009 | 
Author: My brand new Goodman central unit is not working. There is no air coming from the vents and the part that takes in air is not sucking. Please help, it is really hot. I just got the thing at the beginning of summer.
Evilest_Wendy, it is 1:00 am and I have 3 small sleeping children. While it is under warranty, I don’t believe the store is open. And, it is a central unit, therefore not so easy to just take back to the store.
Both the outdoor and indoor units are running. For a little while this morning it started blowing again. That was after I had the fan on for a while. I now have it off completely.
Okay, problem solved. My father-in-law is my A/C man. He used a different refrigerant in 4 units including mine when he installed it and now all 4 have gotten a leak. There reason it was not blowing is because it froze up due to low refigerant. He charged it and is coming back to find the leak this week. Thanks for those who had actual advise.
It was not installed incorrectly. The refrigerant is the culprit.
Does the indoor fan only come on?
If no, then there may be a problem with the low voltage supply, likely the transformer located in the indoor unit.
So, both indoor and outdoor are running ?
If there is a little cold air coming out of the vents but not very strongly, the evaporator may be freezing up. When that happens the ice prevents air from passing through it.
A freezing evaporator is caused by low refrigerant due to a leak.
The short term repair is for an ac company to re-charge your system with more refrigerant.
A brand new unit should not have this problem, therefore, I suggest that it was installed incorrectly and the ac company should stand behind their work and repair this wo charge.

Should still be under warranty. Take it back to the store where you got it.

Call your installer or a/c tech. From your information it appears there are multiple issues — interior unit not blowing, exterior unit not chilling air. If it is blowing air constantly but not necessarily cooling the air, then you have an issue with lines freezing. This could be a result of inefficiency of your home, improper freon levels, dirty coils, dirty filter, etc.
