We had one condenser stop. They came, found an electric problem, sent the electricians in their group, ordered the required electrical panel and we are back up and running.
These people REALLY know what they are doing!!
Corey Mayo took care of it this morning- he was polite, informative, and efficient.
I was very pleased with GEM plumbing. They came when they said they would and explained everything. I would highly recommend them.
Gem has always been my lifesaver and yesterday they came through again. When GEM came yesterday for the annual boiler cleaning they discovered that my boiler was leaking carbon monoxide gas. It had not been leaking the year before so carbon monoxide leaking from your burner. It’s like a tire that’s going flat in the air is coming out. It only gets worse. They gave me an estimate on replacing it, I did some research and they said that they couldn’t install it the next day. The price was in line with everything I had researched and the Bernar rated very high on Trustpilot as did the warranty. Having worked with GEM before, I trust them and I made the deal. Today two men arrived two more came then the Electrician.They got the old burner out they got the new burner installed. They cleaned up the basement and I now have heat and no carbon monoxide.Thanks for being there again GEM.
John arrived within the time window, was courteous and professional. He explained what he was doing throughout the service call.
