Conn Mechanical Systems Services

I rarely write reviews, but I feel compelled to let other consumers know about my experience. Conn installed my Weil-​McClain boiler 6 years before I moved into my home in 2011. I had his people work on it once in the 3 years that followed, along with several other HVAC and plumbing contractors because the system never worked properly. It locked out continually, and I would wake up freezing cold and worried my pipes would freeze. This past spring the nine year old unit was leaking gas into my home.
The first people I called after the gas was shut off was Conn Mechanical to diagnose the system. They came out and claimed that they repaired the leak. That day the gas company was back at my house saying the unit was pouring gas into my home and shut my gas off again. Conn Mechanical came out a second time and took the unit apart, stating something had «cracked» and my best option would be to replace the entire unit. They never even put it back together. Just left the burner assembly and gas valve laying on the floor next to the unit. The owner came out and said it would be in my best interest to replace our American-​Made Weil-​McClain unit with a South Korean $ 10,000 unit.
I had insurance coverage for any crack in my heating system, so I contacted my insurance company and they sent investigators out to inspect. Much to my surprise, the insurance company deemed the unit repairable. I called another HVAC contractor who stated they could repair it but I would of course have to pay them to also reassemble the unit first so they could diagnose what the problem was. Well $ 2,000 later the unit runs perfectly, we have had no lock outs and my home is safe from gas leaks.
They lost my trust. Conn tried to up sell me an entirely new unit when all I needed was a repair, that was likely a result of a poor installation in the first place. Their technician and owner were unable to correctly identify this problem. Be cautious, and make sure they put you unit back together when they say you need a new one, and get some quotes from other HVAC contractors before going with them. The only thing they did to me that was fair was not bill me for NOT FIXING my unit two times, had they I would probably be taking them to court.
