Hi. Getting bids for a new gas furnace in the house (don't need AC). We got a couple bids, and they all gave them for the 80% efficient furnaces, not the 90%+ efficient ones. They said that we wouldn't recoup the cost of the more efficient one through utility savings , and that the 80% efficient one has very few moving parts, and thus has less need for repair and maintenance, whereas the high efficiency ones (some claim >97%) are far more complicated, and thus more susceptible to breakages/misalignments/etc. Furnace brands were Bryant and Trane.
Can anybody speak to any of these issues, or share about their decision in a similar situation? Also, the local gas company offers a $200 rebate and a $350 tax credit to get a >90% efficient unit.
Thanks, h
