“Great service, that’s why we’ve been with this service company since nearly 17 years. Highly recommend this furnace servicing company.”Lawrence Cynthia


“Reached the emergency hotline for a furnace issue. Understandably they were very busy on a snowy evening but Eli managed to drop by just before midnight to get it working!” – Zayan Khandker


“Fantastic customer service. Furnace died, got a quote from Brian and he was great and explained the different furnaces. Bonus was they were able to come early the next morning so I wouldn’t be without heat for another night! Highly recommend Harding to anyone, fantastic customer service, which seems to be missing from some companies these days! Thank You Harding! Great job!”Tammy T
