My ACís compressor fried last night. It is a Carrier Tech 2000 SS, model 38TRA048330, located outside of my house. I think itís about 5 years old 12 SEER and 4 tons AC. So itís time to decide whether to replace just the compressor (not sure if itís still covered under warranty), the entire AC, or even the entire HVAC (13 years old furnace model NUGK100DH11. Not sure what itís).
My house is located in Rockville, Maryland. It is a 3-level house with the furnace resides in the basement. The first and second floor is about 2600 SF. The second floor is typically 6-8 degree hotter in the summer and colder in the winter than the first floor.
Would you please provide suggestions/recommendations as to if my HVAC system is adequate for heating and AC or if itís marginal? Where should I go from here (I'm asking friends and relatives for HVAC references at this point)?
