They installed a 2 stage variable condensor furnace for me in Edmonton. Lasted one year due to faulty install and replaced under warranty. Now it's been 12 years and the second one is shot. I'm told it only lasted about half the time it should. Not installed properly: too big for the house, and cold air opening too small, both of whcih resulted in the thing cycling too often and running too hot. Also, should have been on a base and not slanted properly for condensate managemant. So that's 2 faulty installs. No I do not recommend this company.
