Iv been working on a carrier apac ducted. The system is about 15 years old. The unit apparently used to cool the entire house quite well. It is a 17kw R-22 reverse cycle. And now it takes along time to cool the house just enough to be comfortable. I have cleaned the indoor and outdoor coils, changed the filter material in the filter, and it still hasn't helped. The refrigerant charge seems to be ok going by the gauges and sweat on the suction pipe. I have taken some temperature readings and was hoping if someone could tell me if there is something wrong or not.
Temp on the indoor 32 C
Temp off the indoor 22 - 23 C
Temp on the outdoor 30 C
Temp off the outdoor 45 C
Suction line pressure. 9 degrees C
Suction line temp 11.7 degrees C
I was a bit worried about the super heat, should it be a lot higher than 2.7 degrees?
