1 Furnace Heat Exchanger Replacement
I have a Ruud 90+ propane converted furnace 105000 BTU that was installed in 1996. An A coil was also installed above the heat exchanger. as part of an add-on AC system. The refrigerant is R22 and the system was added in 2000. Both systems are working extremely very well. I have done minor work myself on the system ( replace inducer blower, igniters, cleaning the burner ports, new gas valve, gas pressure check, cleaning the AC coils & condensate drains, replacing furnace filters regularly). I have CO monitors and check the heat exchanger for leaks each season. I don't run the AC much (maybe 2-3 weeks per year) since I live at a high elevation in the Pocono mountains. I want to purchase and install a replacement heat exchanger Ruud/Rheem AS61805-20 cost about $3000 if I can find one. The other alternative is a new furnace and AC system (unless I can pump down the R22 into the condenser unit and have only the A coil replaced). I could also go with a heat pump propane backup. How would you technicians approach this? Would you replace everything or replace the exchanger?
Is dit een goede vraag?
I’m not familiar with the unit you have, but last year I replaced a 20 year old Carrier gas pack heat pump/ AC unit with one of their sub brands (Comfortmaker)so far it’s been a welcome difference. I don’t know if any of this is help to you, but I thought I would chime in. Best of luck to you.

@jthomas27205 What refrigerant does it use?

Did you ask local hvac companies for assessment, replacing only the heat exchanger? There may be valuable opinions for or against replacing one and not the other with long term ownership considerations and whether diy is within state regulations governing diy hvac replacement. There are hvac forums that can help with specific questions, answered by licensed hvac people willing to provide expert help. Some forums are for professionals exchanging info and frown on public questions while others are helpful in providing a broader perspective covering costs, maintenance, pros and cons about diy installation, and more.
