what size home? what size area will this system cover?

a couple of things bother me about your proposal.

1.has dealer provided you an AHRI matching number that confirms qualification for tax credit?

2.is evap coil quoted a Carrier coil or a third party coil? if third party, I would not have it. You want the correct matching tin plated Carrier coil.

3. for your area/climate, an 80% eff furnace paired with a straight AC condenser is a dinosaur. consider a good matching heat pump condenser.

4.The Infinity 80% eff furnace is good equipment. But you would be making a mistake not to correctly pair with the Infinity controller.

5.Yes, you should insist on a new and properly sized refrigerant lineset.

6.what kind of filter rack? for a 1" filter? if so, do it right and install a good 4-5" pleated filter media cabinet. these filters last up to one yr before changeout.

stay away from trane's XL16i. XV80 with XL15i or XR15 heat pump would be fine but might be problematic qualifying for tax credit.

Thank you very much for your response. I know from reviewing this site that you offer much valuable help to posters!
I am replacing existing 2.5 and 3.0 ton units. The house is about 4500 sq. ft. and those always did the job.
The coil is 3rd party. I will request a Carrier coil and new linesets.
The furnace is a 2 stage Comfort Series with variable speed blower, not Infinity. I want a controller that can slow down the blower in order to dehumidify in the cooling season. We run the blower year-round. I am unsure whether the A/C and furnace need to talk to each other beyond that and am unsure in the Infinity controller can do what I want (with the Comfort Series furnace). I have read a lot about the Honeywell IAQ. Will that work with my system to get what I want?
If a heat pump condenser is good for the MidAtlantic climate, then I will ask for one. I will also ask for pricing on a media cabinet.
Thanks for the advice on Trane! I will post back what the Trane guy says, as well as any modifications from the Carrier guy. [He is very old school - maybe a dinosaur, too!]

I am sorry - I misspoke.
The furnace is Infinity and the AC is Comfort series!

john

you are correct about the Infinity 80 furnace mdl.

I don't mean to be so opinionated but again an Infinity furnace whether 95% eff or 80% eff without the matching Infinity controller is simply a mistake. work with the dealer on the pricing. ask dealer for AHRI Directory matching number to verify you qualify for the tax credit on the condenser side of the system.

IMO

Your opinion is valuable and appreciated. I will ask Carrier for the following changes:
Infinity thermostat/humidistat
Heat pump condensor
provide ARHI number
provide tin plated copper Carrier coil
THANKS!

We have allergies as well and have a Space Guard filter (Aprilaire) system in our house which has been one of the best things in our house. We are getting ready to build and have already requested that the space guard be placed on both the upstairs and downstairs units. Some something to consider.

Here they are. one 3 ton and one 2.5 ton.

Carrier ARHI 3656405
58CVA909-16 80% Infinity 2 stage gas furnace
CNPVP3717ATA tin plated copper coil
24ACC636A003 3 ton Comfort series A/C
TP-PAC EDGE Programmable Thermostat
Cost $6380

58CVA070-12 80% Infinity 2 stage Gas furnace
CNPVP3014ATA tin plated copper coil
24ACC630A003 2.5 ton Comfort series A/C
TP-PAC EDGE Programmable Thermostat
Cost $6380

Both Carrier systems come with Perfomance series media cabinet.

Aprilaire 4200 series SPaceguard media cabinets 2 at $225 each

Both say I have super air flow and neither will change the line sets. They are in 'great shape' and run through finished space. WIll clean, flush, etc. Incl is new electric disconnect and poly pad for each system.

The above costs are the prices I pay the contractor. I also get a federal tax credit of $1500 plus a Va. state grant of $2000.What tips the scales in favor of one over the other?

Correction - the carrier costs are $6380 and $5885, all in. The Carrier media cabient is the EZ Flex Performance one (likely good enough, as we are moving in 3 years and not gold-plating this set-up).

Here they are. one 3 ton and one 2.5 ton.
