I have to replace the inside and outside unit. It was the condenser coil on the inside unit that has a leak and froze up. It is a gas furnace. I could replace the outside unit and the coil in the furnace for around $8,000 and then something else would go out so it would just nickel and dime me.
My youngest daughter had to have theirs replaced about 3 years ago for $11,000 same company doing mine. The company said since COVID everything has gone up.
My oldest daughter had hers replaced 8 yrs. ago (different company) and it cost her $8,000.
