Great web resource, thanks.
I just bought a new custom built home that had a great inspection today. I got a steal on it. The only problem is the builder placed 2 "builder quality" Furnaces in, Trane 80's, one in the attic one in basement for a 2 story 3300 ft house. The J load is rated for 1.5 tons each, 16, 923 BTU's. He hadn't installed the A/C yet but has an allowance for 2 Trane 10 Seer, 2 ton units. The house is in Colorado and is insulated very well. I was planning on installing better A/C's because of sound and effieciency, thinking Trane 14XLi's or 16XLi's. I know I have to replace the coils to do so. Should I just go ahead and bite the bullet and upgrade the new furnaces now? I plan to be in the house for 7 -10 years
(I think). Is it worth it? It is a substantial amount of money to do so.
Any help would be appreciated.
