Best Pipe Repair Or Replacement in Saint Paul MN

2 weeks after I had McQuillan out to install a motor in my furnace because the heat wasn't blowing out, I turned on my AC since it's now in the 80s outside. Well, no cold air blowing and the condenser is not running at all. Based on my interaction with the tech they sent out. I had a feeling that he wasn't being 100% straight up with me about the issue and the repair price. So I had another company out to check it and they said that someone disconnected the wire to my condenser that gives it power! They also said, there is no way the wire came loose by itself! McQuillan, you all should be ashamed of yourself to cause a problem just so I'd need more service and might have to call you again.
