1500 sq ft house kids have just bought has a 25 year old standard gas
furnace, i could never be normal so have decided to pay for new heat unit.
House has 10 year old central air system in good repair, should it be
pitched or kept with this unit?????????
Thanks all


Based on the furnace needing replacement and not the cooling system, you
should be okay. The newer cooling stuff needs to be all matched together to
make sure you acheive the proper efficiency.
