Should I Replace The Heat Exchanger On My 1996 Furnace Or Replace It?

My gas company red-tagged my furnace due to carbon monoxide leaking, because of a failed heat exchanger.
Should I get the heat exchanger replaced for $1000 (parts and labor) or just get a new furnace for about $3500?
The furnace is a 1996 Tempstar 90% efficiency model.

go to an ultra efficient variable speed system w/a brand name like carrier or Bryant or lennox, add a air source heat pump. 96-97% furnace & a 18 seer a/c to make a terrific dual fuel system, and laugh at those opec countrys let em eat their oil and gas..

The heat exchanger is probably under warranty. Check with a tempstar dealer. There wouldn’t be any reason to buy a whole new furnace. You will not gain much in energy efficiency. For more info check out the furnace page at my source.

You didn’t say if your A/C works off of this unit or not, if it does I would replace the unit as you could repair the heat exchanger and a year or so down the road your compressor could go out on the A/C. Plus I’m sure they have more efficient units now, however before making a decision check to see if the heat exchanger is under warranty, if it is get it fixed…otherwise replace.

If it failed after ten years I would look for a better manufacture.Tempstar should make a product to last longer then 10 years.

It isn’t that old. I’d replace the part and keep the furnace.
