IĎve contacted four authorized Carrier ServAssure HVAC contractors to give me an estimate on replacing my 25 year old Carrier heat pump. Although itís been very reliable Iíve needed to have it charged 3 times in the last 6 years so I think itís time to replace it.
Iíve asked each contractor to give me a price for a Comfort system and a Performance system. I understand that discussing price isnít allowed so Iím just asking for information on the components that two of the contractors have offered for each system.
Contractor AHF has offered the following info taken from their estimate:
#1AHF - Comfort system including outdoor unit 25HBC3 and indoor unit fixed speed FB4. The AHRI certification number is 3698885 and identifies the models as outdoor 25HBC336(A,W)**30 and indoor FB4CNF042+TXV .
#2AHF - Performance system including outdoor25HCC5 and indoor unit variable speed FV4. The AHRI certification number is 3676238 and identifies the models as outdoor 25HCC536A**30 and indoor FV4CN(B,F)003.
Contractor BCC has offered the following info taken from their estimate:
#1BCC - Comfort system including outdoor unit 25HBC336 and indoor unit FB4CNF042. The AHRI certification number is 3698885 and identifies the models as outdoor unit 25HBC336(A,W)**30 and indoor unit FB4CNF042+TXV.
#2BCC Ė Performance system including outdoor unit 25HBC536 and indoor unit FV4CNB005T. The AHRI certification number is 3645940 and identifies the models as outdoor unit 25HBC536A**30 and indoor unit FV4CN(B,F)005.
I canít find much information about each component in the systems. I think 336 or 536 indicates a SEER of 13 or 15 and the 36 means 3 tons (3 X 12,000 = 36,000). What is the difference between HBC and HCC on the outdoor units? The indoor unit model numbers are a mystery to me. Are the ďPerformanceĒ systems that I have been offered really made up of ďPerformanceĒ components? What is TXV? Are any of the given model numbers incomplete, ambiguous or open to interpretation? Are the components offered desirable? Although I don't want to spend the money that an Infinity system would cost, I want more than just a base system. Any and all help deciphering this and recommending unit models to choose is greatly appreciated.
