BACKGROUND:I'll try to make a long story short. For the last couple of years I have been locked into a "home warranty" that has been "repairing" my upstairs a/c unit....quite unsucessfully. The old unit, which was a 1.5 ton Goodman always cooled well, but leaked out freon in about 60-90 days. After many many times of just charging it up, the warranty company finally paid to have the evap coil replaced last fall. It worked through the fall but this summer was empty of freon again. They replaced the outside unit with a new Payne 1.5 ton 13 seer unit this April.
PROBLEM: On a warm humid day (Alabama heat 90-95* and high humidity) the system cannot meet the cooling demand. My upstairs is set on 77 or 76 and by 4:00pm it is usually 81 or 82 inside. I called the HVAC company and they said call the warranty company. They want me to pay more money and I'm getting the run around. My other unit that controls two floors works just fine regardless of temp or humidity.
Now for the question: I have a friend who is a building maintenace tech at our church come out and check the pressures. He said they are perfect, but the unit is only cooling 5 degrees from return to register. There is no condensation on the low side line outside. What would cause good pressures but no cooling???? My friend thinks it may just be undersidzed...but the old unit was the same tonage?Please help. I'm supposed to have someone come out in a coupe of days...but I just can't trust them.
