I have a dilemma. I have a 32 year old Moncrief furnace (installed in 1976). It actually works fine, but it is time for a new, more efficient model. I also have a central A/C installed in 1991 (17 years old). I am trying to decide if I should keep / salvage the A/C to save cost.
Am I throwing money away by replacing the A/C when I replace the furnace?
Is it even possible to salvage an existing 17-year-old A/C when replacing the furnace?
Or, is 17 years plenty of life for an A/C? Should I bite the bullet and replace the whole system?
Any advice would be greatly appreciated. Thank you!
