Goodman R22 compressor died. Upgrade or replace?
We just moved into 9 year old home and because of cold weather could not test the air conditioning unit. We turned it on for the first time and it died within a day. A friend recommended an ac technician he's used for years who came out, spent an hour with me and felt bad charging anything after what he found. Turns out the freon was leaking inside the compressor and outside. It's a Goodman CLK60. He said Goodman uses same compressor as other high end units but keeps prices low by not advertising like the others. He suggested we just replace the unit and he'll add the freon since they can't sell them with freon. He's a registered distributor for many different brands but said Goodman is good if installed correctly and it's best to match with the unit in the attic. The rooms square footage adds up to 2200 but the house was listed as 3200 square feet (2 floors). it's a 5 ton, 60,000 BTU system. I have a few questions:
1. is the size of the unit good? I was concerned it had to work too hard and that led to breaking.
2. he said the cost of labor to take apart the compressor and find the leak and then order the part, replace, etc may make it not worth it compared to getting a new one. it's my call. should I replace or spend to find out where leak(s) is happening?
3. he said it would cost a ton more to go to R410a system. he would flush the copper line if we went that route, not re-run copper. but we'd have to replace the attic unit (forgot what that's called). we plan on being here 40+ years. does that length affect our decision? Goodman has the optional lifetime warranty program which is appealing.
4. We only have 1 unit for a relatively large home. Does the desire to someday convert to 2 zones affect our decision making process?
I know most people are skeptical of technicians, but I totally trust him. My friend is a seasoned builder and has used him for years. He's an old timer who seems to know his stuff.
