Am I missing something in these quotes?
Hi all, recently made the decision to replace my HVAC system. Old unit was a 23 year old interior furnace coupled with a 17 year old exterior weathermaker heat pump unit. Defrost was no longer functioning, so I felt no need to throw good money after bad after getting a $300 repair quote. Called around, had several pros come out and quote me a new system. I'm strongly leaning towards the carrier quote, but I'm nervous because it seems so low.
3.5 ton Amana: ASZ140361B unit coupled with AEPF42016C handler for $3900
3.5 ton Carrier: 25HCC542A unit with FV4CNB006 handler for $4480
3.5 ton Trane: XL15I unit with XV90 air handler/furnace. He didn't give more specific numbers. All for $6200.
One of the three did a manual load calc, and said that I could go down to a 3 ton, but with the way I program my thermostat, it may be better to stay with a larger system (very large swings between sleepy time and awake time). No quotes include rebates, since I only qualify for $300. All include a completely new charge line and refrigerant. Two include moving the hot water heater to make servicing and filter replacement much easier (currently, handler is obstructed by the HW heater, so I have to bend filters to fit them in). The Trane and Carrier installers seemed to know their business better than the Amana dealer, who mentioned an ASZ16 system for 4900, but I like the reputation of the trane and carrier. To me, it seems like a no brainer to save over $1000 for an equivalent system.
