I have a 1970’s house up here in Minnesota. My air conditioner is Lennox brand HS6-261-8FF-FW. Last summer it stopped working, the compressor would cycle and the fan would not spin. A local service tech removed some refrigerant and it worked for a month and then died again. We are selling our house and the compressor not only is broken, it is unsightly. Researching the part number I learned that it is 2 ton or 26,000 Btuh. I would like to replace just the compressor in interest of saving money. My question is what to replace it with. I found that Lennox has a Merit series 13ACD that uses R22. (I think that mine is R22). Would that be a good economical choice? Should I stay with the same type refrigerant? My furnace is a Lennox as well. What price range would I expect to pay for a compressor unit? We have several local HVAC companies around but I would like to be informed going into this and any information would be most helpful since I am likely to take it in the shorts on the sale of my home.
