Not often do you see such technical expertise combined with superior customer service! I called Sully from a referral in the business who was much too busy to come out on the first cold day in Calgary. Suffice it to say that I hit the jackpot. After working 16 hours straight, Sully arrived at my house early Saturday morning to quickly and effectively diagnose and fix the heating problem. The commitment to his trade and very reasonable pricing is unheard of. Sully will be arranging my furnace tune up next week as well. Can’t recommend him highly enough!
