I must replace my 25-year-old electric furnace soon. When I bought the house 6 months ago, I had the gas company run a line to the house because I expected the replacement to be a gas furnace. Now that gas prices are increasing I am looking at dual fuel units--an electric heat pump with gas furnace. Living in middle Tennessee, I like the idea but are there potential problems I need to be aware of? Does the up front cost pay for itself in a reasonable amount of time? The bid I am most seriously considering is for Trane's XL 1200 DCY, either the 2.5 or 3 ton for my 1600 sq ft home.
Other posts I have read tend to recommend the extended warranty. The contractor offered a warranty of 1 year on labor, but at least one post insisted on 5 years.
Thanks in advance,
