Dennishayes in Ancaster

I really don't understand all of the glowing reviews here. Based on the writing style of some of these reviews, I suspect some were fabricated by the company itself. The reviews on Facebook actually tell a more truthful tale about this company. 1st visit: rude guy that barely talks and is very gruff in his responses. Doesn't explain what he's doing when I ask and he doesn't do a very good job because our vents were still emitting dust a month later. 2nd visit and 3rd visit: called to fix the furnace. First guy says it's all fixed after he's done. It breaks down a week later. Called again to fix it again but they charge me again even though the first guy clearly didn't do his job properly. Also the receptionist was very rude about me inquiring about the furnace issue because she felt that it was our fault that it broke down the second time. I have never been so baffled in my life. Do not go to these guys. There are a ton of other air duct cleaners and furnace repair guys that will do the job way better.
