I had a new furnace and tankless heater installed a year ago by another company. During the recent cold snap, the intakes began to badly frost up, at which point I realized all the venting was incorrectly installed. Not wanting to go back to this installer because of my concerns with their work, I put out a request here in homestars and got a quick response from Len at Tempasure. He sent out Adam the next day to look at it, whom I could tell within 2 minutes of speaking with him clearly knew what he was doing. He managed to clean up and rectify the mess the previous company left behind. I’m confident In the quality of their work and would definitely give them a shot a bigger jobs in the future.
