Your family friend may be thinking of evaporator temperature, not discharge air temperature. There's a big difference. And at that, normal evaporator temperature runs between 40 to 45 degrees. 35 is coming too close to a frozen coil if airflow is poor, which it often is.Originally posted by notcool
well... here's another question for those in the know. The AC coils are at 55*. I friend of the family who's a technician (he hasn't looked at the system though) says it should be much colder, at 35*. Is this true? The technician who looked at my place said 55* is fine since the incoming air is at 80* and anything around an 18* delta is fine.
Your condo situation to me sounds like a supply ducting problem. If you have moist, mushy drywall above the air handler, that's probably where your problem is. Could be the duct is loose at that location, allowing moisture to condense on exposed metal duct surfaces as the cold air escapes the coil and meets the warmer, moist air in the chase.
