4 tons is likely the right fit for your size home given the sizes the Infinity 16 is offered in, but for the furnace, was a heat loss calculation done to ensure proper sizing? You're probably looking at the 80k or 100k model with that size home and airflow requirement. Was the ductwork looked at to make sure it was the proper size for the new system? You say the old system worked great, so this is a good indication that ductwork is in good shape, but it never hurts to make sure when you're spending $10,000. As you well know, finding the right dealer is key to a properly functioning and performing system. The price is about what I'd expect for such a high end system, could be closer to $9000 I would think, but every dealer has different pricing and it varies by job and area. I'm not sure I'd add the Trane CleanEffects. It's a good cleaner, but it requires good maintenance to operate effectively (as do all EACs), and if I were to install one, I'd use the Carrier Infinity air purifier, since all your other components are Carrier. I like to match everything when I can. The humidifier is a good idea; it can add warmth to the air and more comfort overall. I would also, if you can afford the extra cost, keep the dual fuel setup with the way electric and gas rates are climbing and changing. $675 is quite reasonable for this add-on--I've seen higher upgrade costs. Glad to see the tin-plated coil! With the heat pump as the primary heat source, usually I'd say go with the 80% variable speed backup furnace, BUT, with the $1500 tax credit for 95% AFUE furnaces, I would stick with it. Hopefully your dealer has discussed this with you and if not I would ask about it so you don't leave it out.

Hope I've covered anything... let us know if you have any more questions.

what is your electric rate-cost/kwh?

what is nat gas rate-cost/therm?

post back..

I am not a fan of EACs like the Trane Clean Effects. They can be problematic if you don't adhere to the regular cleaning/maintenance schedule, they do consume a small amt of electricity, and they do emit a small amount of ozone that can be an irritant to some. I prefer a good 4-5" pleated media cabinet that can last up to one year with easy changeout.

you definitely want a new system that qualifies for the Fed Tax credit of up to $1500.

you could save some $$ with Carrier's Performance 15 HP either 3 1/2 ton or 4 ton mdl-"H" version please.

Exact same HVAC is available from Carrier's sister company Bryant and may be less expensive.

There may be some mfg rebates from Carrier/Bryant this spring. Check with dealer.

I haven't put much thought in to my heating & air conditioning system. I didn't know how advanced they all were.

I would definetly do the heatpump. If gas spikes again in the future you will be ready.

I believe this thread is dead...........
