Dual-fuel heat pump quote review - thermostat advice needed
I’m in the Seattle area and am replacing a 25+ year old gas furnace (Trane XV80) + AC (Rheem 3.5 ton) in a 3200 sqft two story home. I am getting several quotes and one I like the most so far is from a Mitsubishi Diamond Contractor specifying the following for about $18k:
* Heat pump: Mitsubishi PUZ-AK42NL (42k BTU variable speed Hyper Heat)
* Furnace: American Standard S9V2 (80k BTU, 2-stage, variable speed, 96% AFUE)
* Coil: Mitsubishi PAA-BA42NL (42k BTU evaporator)
* Thermostat: Mitsubishi wireless
* Filter: Honeywell MERV 11
Install includes nitrogen brazing on line set, pressure test, 350 micron vacuum, sub-cooling charge verification, pad with anti vibration mounts, permits and inspection. 2 year labor with extended warranty available.
Two questions:
- Thoughts on the specified equipment and quote?
- Thermostat options? I have a 3rd Gen Nest with remote sensor (upstairs) which I like. I have read not great things about the Mitsubishi thermostat, though the PAC-SDW01RC-3 doesn’t look terrible (not sure if it will work with the system), but also the proprietary protocol needing a special communicating thermostat. I’ve also read about the PAC-US445CN-1 thermostat adaptor and wonder if that’s an option, or any of the Honeywell ElitePRO or Ecobee thermostats?
Thanks for any advice!
