Heating and cooling systems

All systems were removed from service for upgraded systems by my HVAC guy. Lennox 50,000 BTU gas furnace with 2ton central airconditioner. Works good HVAC guys customer upgraded to a higher BTU system. $500 Armstrong 80,000 BTU gas furnace with 2 1/2 ton central airconditioner. Works good HVAC guys customer upgraded to a newer system. $500 Carrier 2 1/2 ton heat pump and air handler with 10KW auxiliary heating elements. Works good HVAC guys customer upgraded to a newer system. $500 All systems were removed from service in good operational condition. All systems are R22 compatible. I also have a ream 410 heat pump system with airhandler and 10KW auxiliary heating elements that is about 5 years old. My HVAC guy said the reversing valve is bad. Being that it is only a few years old I will sell the air handler for $500 and if you want the heat pump as a parts unit you can take that with you.
