Building a new home, approx 3400sf, 2 stories. Western Washington weather I've read enough of the posts in this forum to know it's more about the installation than the brand of unit that will create a good system, but I'm going to have to go on a bit of faith here that they'll do a reasonable job. I knew no HVAC contractors personally in my area, so i requested 3 bids purely on word of mouth from my other subs. All 3 used different brands, and they're roughly 4k in difference between the least to most expensive.
For the more knowledgable folks on this forum, which would you choose out of these 3 (or none?)
1. Carrier 4 ton, Performance Series Heat Pump System w/ Puron & Indoor Electric Variable Speed Air Handler w/ 20 KW Strip Heat Coil : $XX (2nd most expensive)
a. Carrier Infinity 16 Series Heat System Pump : $XX+Y (most expensive)
2. 15 Seer HSPF 9.25 Rheem System w/ 410A heat pump w/ matched Rheem 3 ton RHKL variable speed air handler: $(middle price)
a. Rheem 3 ton RPNL 16 seer two speed heat pump w/ 3 ton RHPL 16 seer air handler: $XX (middle price)
3. Trane 3.5 ton variable speed air handler w/ 19 kilowatt strip heat & 3.5 ton XB13 Seer R-410A heat pump (seer rating of 13.0 & an HSPF rating of 8.0): $XX (cheapest)
