I've decided to take advantage of the soon to expire tax credit and replace my furnace and AC. The AC is the original unit from when the house was built 27 years ago (3 Ton). To qualify for a local utility rebate a contractor recently did a test on the unit and concluded it's operating at 7.8 EER (after adding a lb of Freon). My furnace is an 8 year old Frigidaire 80% AFUE. While it's not nearing the end of its life, I want to replace it with a more efficient unit.
I've had several contractors out to give me bids. Those that didn't do a load calculation I won't consider. I've had three perform load calculations, but how does a layman know whether a load calculation was done properly? I've had two contractors tell me I need a 4 Ton AC unit even though my current unit is a 3 Ton.
The general consensus between the contractors is that I'd be happiest with a heat pump and a variable speed, two stage furnace. My lists of priorities, in order, are: apply for the tax credit, lower utility bills, and increase comfortability (especially in two upstairs bedrooms).
The one bid I've received so far is the following:
York YP9C Furnace
York YHJF Heat Pump
Is York a decent brand? I really have no idea since there doesn't seem to be a lot of manufacturer comparison information on the web.
The one contractor that I received a bid from is at a great price (I think), but I have concerns about the company since it's an electrician company that recently decided to expand into the HVAC business. The reviews I've read about the company are all good, but they're all for electrical work.
A little extra info if it helps: I live in the Kansas City area. My house is two stories with a total of about 2000 sqft. All windows are double pane.
Any advice is appreciated.
