I'm looking for some feedback and advice regarding a 10 year old Goodman 5 ton 12 seer split ac/furnace unit. I was informed that it needs a new compressor (covered under warranty) along with a few other parts (filter dryer, capicitor, contactor board, and r22 refrigerant. The warranty covers all the parts, just not the labor and the freon. The contractor suggested replacing the other parts along with the compressor to make sure it is a job well done.
1) Not sure how much freon is needed to fill the entire system. There is probably 40' of line going from the outside ac unit up to the condensor in the attic. How many feet of line can you fill (7/8's) per pound of freon (R22)?
2) Was also quoted install of brand new system (goodman heat pump and air exchanger).
3) My main concern is I don't know if it's a good idea to spend money on fixing the current unit (not sure if the coils will eventually go bad) or put the money into the new unit. If the coils do get a leak, can it be easily fixed?
Any and all feedback is appreciated. Thank you.
