"Q. I would like to replace my old inefficient central air conditioner with a new higher efficiency unit. Do I have to also replace my furnace?
A. The simple answer is NO, you do not have to replace your furnace. If the furnace was sized and has operated properly in the past, there is no need to replace it. The upgrade in air conditioner efficiency is not dependent on your furnace, as long as the outdoor air conditioning condenser and the indoor air conditioning coil are matched for efficiency."
is what warm air stated ture. One contractor told me i can't upgrade pass a 12-13 seer with a 10 year old furance. any higher seer and i need a new furance. who is right???????
