I got a price quote and load evaluation from a HVAC company. They did a thorough job examining both the air return system and ducting.
They had recommended the following:
Heat Pump: 25HCA330A003
Evap Coil: CNPVP3617ACA
Several knowledgeable people here suggested upgrading to the Infinity 96 58MVP.
The installer and technician were both just out here today reviewing the job - starting tomorrow and I brought up the subject of upgrading to the 58MVP.
Now. These two guys don't really have a dog in the fight - as it were - here since they are not "selling", just installing for the heating contractor.
Both said that the Infinity is an excellent furnace and they could adapt it to the vent flue through the roof.
One said an interesting thing.
He said "You are going to be using a big heat pump, and since electricity is cheaper here then gas, the Infinity is going to be major overkill."
The house is a 70s ranch - 1,750 square foot, and pretty well insulated with new double pane vinyl windows and is ducted and properly set up for 1 zone. In the past the house heats up evenly with very few cold spots.
He said that if it were him - he would stay with the base model 58STA as it is basically a secondary heat source and the heat pump will be doing the vast majority of the work.
He also told me that what was recommended is well suited for the house and the climate conditions - as we don't get very many really cold days (weather below 32 degrees). As to noise difference, the installer said that since it is in the garage you won't hear the difference unless you are out in the garage.
The technician said "Of course we would be happy to make more money, but in your case, you really won't see any cost savings, and it's bigger then you need, so why spend it." He also said that with the recommended 58STA, they opted for the 3 ton blower size (?) which is a bit bigger then what is being replaced and it's a 70K unit.
Now, granted, I don't know much about HVAC - that's what I am depending on you folks for - the more voices the better. I don't want complete overkill. They both agree that with the slightly larger size heat pump and evap coil system, then what it is replacing will provide the house with more even heat at a lesser cost. The old AC was 2 ton, the replacement is about 2.5 ton. The 58STA they say is more efficient obviously then the 20 year old unit it is replacing which was a single stage Rudd Deluxe 80 Plus furnace.
Since I don't know just how many years experience these guys have, I really have no way of knowing whether they are talking from experience or through their hat! The only thing I know, is that my neighbor who 2 years ago or so replaced their aging furnace (same make and model as I had - with the Carrier), they have been very happy with the installation and performance. Their house is roughly the same size, but no new windows and the floor plan is different. They used the same HVAC company, but there has been some employee turn over and the guy who did the install no longer is there.
I'm really at a loss here, and I have to make a decision here very soon.
I know this is a bit long, and appreciate your bearing with me on this.
Please help an ol retired Puddle Pirate (Coast Guard) guy out with some advice.
