I have used a sole proprietor AC guy for quite some time. But I am constantly nagged by doubts about whether I could do better. I have a few rent houses. The AC condensor went out on one last Nov. and I wasn't prepared to buy a completely new system, so I asked about a used condensor and he happened to have one and installed it for a reasonable price. Since then I read up and it seemed like it is foolish to replace a condensor without also changing out the coil. This is a very old system.
The other rent house he did a check up after purchase and okayed the system and then my husband had to go back with an air compressor and clean out the line because we had water--a few days later. And a month later the bearings went out on something and I had a $ AC repair from a company who worked weekends--which he doesn't.
The house before that he okayed the system when we had the house inpected. After the remodel and before renting itit was summer and the AC wasn't very cool. He came out and added a wire kit of some sort and said we were good--until we went out of town a month later and the AC compressor went out. The guy our tenants called said the wiring problems were common before compressor burn out. (We were out of town).
But he has put two systems in our house and they work fine. And he has 20 years experience. And he is not stupid. But I wonder... It seems like he gives us advise that benefits him and not me long term. I just want to spend my money wisely--I could have paid for the coils when he installed the condensor andhe knows that. I just didn't want to spend $ if I didn't have to on a rent house.
Now if I want to change out the coils it is labor intensive $$$
