The company was recommended by Enbridge. The sales representative was polite and knowledgeable and we decided to go ahead. The installer came on time, finished his work in 3 hours. He was in a hurry. When we asked him to test that the new thermostat can start and stop new furnace, he was rude as if we did not understand how it should work , did nothing and left. Then the furnace worked and worked and temperature increased up to 30 degrees against 18 degrees set up by the thermostat. We stopped the furnace manually and called the company again. The technicians was sent same day, they replaced the thermostat, this time they checked that it can manage the furnace.
