I'm not sure if it's a heat pump system, however here's the model number:
It runs, the fan comes on when I set the AC to say, 68F (It's currently 77F downstairs)
Is there a way I can tell if the compressor is on if the top fan is spinning? Checking the feeder line now to see if it's cold.
The suction line (wrapped in a cover) appears to be air temperature and not cold at all, and it doesn't appear to have vibration other than maybe from the fan being on, the fan is also blowing cooler air compared to the other unit.
What are the average costs for each possible fault, considering if I go through a HVAC person (someone local)?
