After reading the reviews on this site as recommended by the salesman, I decided to contract Thomsons rather than a national brand. BAD decision. There were a couple of complaints on this site concerning poor quality installations by Thomsons. I should have checked into those complaints further.
After the furnace install, our water heater stopped working. I also smelled natural gas. I called Terasen. They informed me that the recent work was faulty. They shut off my gas. No heat or water for 3 days in winter. The Terasen inspector suggested I call the water heater install company. A tech from that company completed a service call and informed me that the gas leak was coming from a new line that Thomsons installed. Also, the reason that the water heater blew out was because Thomsons had teed into the water heater drain line instead of installing an independent line. The water heater install company charged me $200 for the service call. I have tried to get Thomsons to correct the install and reimburse me the $200. They ignored me. I have now informed them that I am going to post this complaint to this website, Yelp, Google, and Threebestrated. If they still refuse to make this right, I will take them to Small Claims Court. Update - I filed the small claims court action May 14, 2019
