I live in Northern VA in a 3 story (2 above grade with walkout basement) 4000 square foot Cap Cod built in 1991.
My 1990 build serial number 3.5t Trane XL1200 heat pump's compressor died this month, but the 1990 build serial number 100K BTU Trane XL90 propane furnace works reasonable well on its 3rd blower motor.
I am replacing the whole setup with the following Carrier Infinity:
Heat Pump - Model 25HNA648A, Nominal tonnage:4, 15.5SEER/8.9HPSF
Furnace - 58MVC100-20, Output:variable up to 95K, 95%AFUE, Propane
Coil - CNPVP4821ATA
Air Filter - Standard
Humidifier: Relocate existing AprilAire 700
I am pleased with the price and install is scheduled for this Friday. :::fingers crossed:::
Does this setup sound appropriate for my region and for a replacement of a competent albeit aged system?
Is there any more information I should be getting from the HVAC company prior to install?
Anything I can do to help the install go as smoothly as possible?
Are there post install items for this type of system that I should make sure the installer hits? i.e., settings that may be left at factory defaults, tests skipped so they can get the weekend started, optional equipment not installed, installation options that may improve user comfort, but are non standard?
The owner manuals on the Carrier site for the heat pump, furnace and Infinity control are *super* light, as in barely worth the bits to download them. Is this really what they expect the home owner to use as a information, diagnostic, maintenance guide nowadays?
Thanks for the great site, I have been reading everything hear about the Infinity and the other options offered by the other 4 contractors I got quotes from. I don't think I would have ever been able to make a decision without the information and helpful users here.
