Since he installed our air conditioning, I've had Laurenzo out to fix our furnace and recommended him to neighbours who were just as happy. The guy is great and his prices are the most reasonable I could find. I was completely comfortable having him in my home and I think he left the furnace area cleaner then when he arrived. Any installer that bring his own shop vacuum to clean up after himself without being asked to is worth every penny in my books. He also installed our central air conditioning with custom duct work in a location that was pretty squishy and that one of air conditioning company wouldn't even quote for. When I questioned him on this he gave honest answers and was able to explain why central air would be an option for us. He has also referred us to other trades when we've need suggestions and we've been more than happy with these guys too. Westmount Heating will be the company who replaces our furnace one day. Thanks!
