I was wrong it is suppose to be a 3.5 ton. i looked at my quote. But i still say something is wrong. The tech just left and he took out a strip (he said there are 3 and he took out 1 to see if it helped) he said the only thing he could see was that it was cutting off to quick after cutting on. and supposedly taking out the strip should help. the temperature right now is 74 and i turned the heat on (to check it out) to 77 about 10 minutes ago and it hasn't come on yet.
He told me it is all electric. i don't have a heat pump.
The previous unit was a carrier 561AJX042000 (C.U.)it also says Nanleg 15 KW (FM) #RCAB045-500. The writing is hard to read.
Checked the model #'s on actual units and the outside unit is #24APA542A300 - Puron. and the unit in the attic is #FY4ANF042.
When it comes on i will see if the outside unit is running as someone asked.
