QUESTION:My 17-year-old Carrier furnace has a cracked heat exchanger. I have
received three different quotes that I would like advice on please. My house:
built in 1989, under 1700 sq. ft., rancher on slab, vaulted ceiling in
great room with two skylights, three bedrooms, 75,000 btu gas furnace
in attic quotes: - Amana AMS8 70,000 btu 80%, warranty 20, 5, 2 $3349 (the guy who came
on the service call) - Lennox G40 70,000 btu 80%, replacement 2.5 ton evaporator coil, same
warranty, $3300 - York Choice or Trane XB, 20,5,1 warranty, $2400 or with replacement 3
ton coil $3500 I plan on being in this house another 1-2 years.
ANSWER: Not a 17 year old Carrier Furnace in an attic. If you google life
expectancy of a gas furnace it is about 18 years. It couldn't hurt to get a second opinion. Did the tech show you how he
proved a cracked heat exchanger. According to MSN.com, Consumer Reports, and some realestate report state
that investment in your heating system should give you a 95-100% payback on
your investment.
