Need help with my hvac system.....

11 years ago

I have an ancient system. The outer unit is original to the house, built in 1970. It brand is Heil. And the inner unit unit is a little newer though I am not sure of year and it is a rangeaire. My question is can I buy just a new outside unit and keep the inside unit as is? And it work great? Is that possible for it to be compatible with a newer model? Or do I have to buy a whole new hvac system?

I would suggest that you buy a whole new system. the operating cost on a new system will save you. however, I do not see why you cant mix the old with the new as long as they are compatible. I have had mixed brand systems, but I have always relied on an HVAC contractor to install compatible units.
