Hello pros. I know mechanics, wiring, some plumbing and carpentry but don't have much experience w/ HVAC so any help would be appreciated.
My A/C is on the fritz. @ 14 years old in new construction. Basic contractor quality. The tech sez: "Entire I/D coils is sweating but very dirty. O/D coil is clogged. 62/290. Heat exchanger badly rusted. Contactor are original burnt/rusted." 21degree at ID coil; 82 degrees at ID return temp." Would require to repair: "40 amp contactor; pull & clean blower assembly, clean condensor coil, clean I/D coil & pan, pump down & evacuate w/drier"
Tech recommended a complete replacement of the gas furnace and A/C system. This would be several thousand more than the repair estimate. Does this sound reasonable? Any help or thoughts would be appreciated.
