HVAC replacement and upgrade

Water23March 22, 2013

I have a house (NoVa area) that was built in 1975 with one zone. My Furnace and heat pump need replacing. I am getting bids to upgrade the old system and add a new second zone to my 2 story house with large basement. There is a significant temperature issue with the 2nd floor. I know that I will be getting some upgrades with as the new systems are two stage, variable speed blowers. Also, I will also be redoing my insulation.

So I was wondering -
1)Is there a difference between Bryant/Amana/Rheem?
Original system (100K BTU furnace).

2) In bidding the second zone unit, most say I would not need more than a basic unit as it is not a large area.

3) Are these systems generally comparable.

4) They all talk about communicating thermostats. Should I have them installed on both systems

5) Are they good prices?

Bid #1 - lower zone (replacement) - $8,200
Rheem RGPE-10EBRMR 100,000
Rheem RARL-049JEC 36,000
Rheem RCFN-HM4824 36,000

Bids #2 - lower zone (replacement)- $8,560
Amana AMVC80 100,000
Amana ASXC 36,000

Bids #2 - lower zone (replacement)- $6,300
Bryant 315A 90,000

============================

Rheem RHSL-HM2417 24,000
Rheem RPNL-024JAZ 24,000

Bid # 1 (New Install) - $12,900

I should add that the upstairs new zone has a duct work install as well.

What size is each zone?

Has any dealer performed and given to you in writing a load calculation?

I would bet the downstairs systems quoted are oversized especially on heating.

post back.

IMO

No to calculations. I have 2,300 sq feet plus a 1,000 below ground basement.

Basement and Main Floor are about 2,300 and 2nd flr about 1000
