I currently have a rooftop condenser and a Rheem multistage heatpump/gas furnace with AC. The whole system is from 1988. The condenser isn't coming on, and two repair guys came in and reccommending replacing everything said it would be a big rewiring repair $$. They also advised against heat pumps, and said I should get a new gas furnace, coil and condenser.
Does anyone have any advice? The system is old enough to replace right? (1988) How much should it cost to have this stuff installed (equip + labor + renting a crane to switch out rooftop condensor). Thanks!
