I Had my Furnace and water heater serviced by Brad Sallows and he did a very thorough job. He answered all my questions in detail and was very polite and patient with me. I was a little offended when he offered to take my "junky" old copper pipe off my hands that he saw on the floor. Making it sound like he was doing me a big favour. I guess some of my questions about the furnace my have been a bit naive, but I do know that copper pipe is very expensive in the recycling !!...I should have given him the junk from the side of my house instead lol.
