I need cheap ac repair or replacement in Modesto CA. Suggestions?

[Lynaire McGovern]

I need a cheap but honest AC repair or replacement in Modesto for a fix and flip condo. Repair preferred. I already paid $1000 to one guy who left with the ac running cold but one week later it no longer made the place cold. It works but does not get cold. He came back and the same thing happened again. I believe this is stopping the home from being sold. Any suggestions of cheap, honest and good AC repair places? If not what about places I can replace the AC cheaply? What about Home Depot? I tried CL and Yelp. The yelp guy cost twice as much as the CL guy. Please help! Thanks!
