I am an electrician and would surely appreciate some advice.
I have a 25 year old A/C compressor unit and have been searching for a used one with the same tonnage to replace it with as I cannot currently afford a brand new complete system.
My residence is a townhome and the compressor sits outside on a pad while the furnace and blower with the filter sit inside the garage.
I recently ran across a 3.5 ton Trane XE 1000 manufactured in 1999 but never used for a sweet $800. When I went to look at it the model number and labeling stated it was a heat pump. Can I use this heat pump instead of the standard compressor in my split system? Will the thermostat control the cooling operation of the heat pump in the summer and the gas furnace operation in the winter? Can the heat pump be shut off during the winter or will it work just fine here in Southern California? Can I then replace the other component (blower/furnace) with something that has the same specs as the existing but very old one?
Any advice would be greatly appreciated!
