• I want to thank you and the team for the professional installation of the garage heater. It looks great and so far is doing the job. Not that I wish for colder weather, but I can’t wait to see how warm the garage is when it’s -20 outside. This will be a game changer this winter. N0 more warming up the car before leaving for work.
