First let me explain my special situation. I'm a home owner, but will be selling my house this time next year. My 5 year old R22 A/C unit went out yesterday when the fan stopped turning and the compressor burnt up. The bearings in the fan motor are going bad, but I was able to get it going again. My debate is whether to repair or replace the unit with an R410a. If I was going to be here long term it's a no brainer to replace the unit, but I'm not sure if it's worth the cost to replace it since I'm selling the house in a year. What would my ROI be like? Should I just take the cheapest route and hope the fan motor holds up for a year or could it help selling the house by having a newer unit? I'm so torn. Obviously I WANT to go the cheapest route right now, but is it the smartest in the long run? Any help is appreciated. Thanks.
