Air Quality Dunrite

I live in a 4 storey townhouse with my air conditioner on my roof and my furnace on the top floor. When my air conditioner died of old age, I had to get it replaced. The space in my furnace room is tight, so I decided to get my old furnace replaced at the same time. As you can imagine, this was a tough job. I got some quotes and felt most comfortable with the competitive quote from Air Quality Dunrite. I was pleased that they didn't try to up sell me but rather recommended the most appropriate appliances for the job.They were very professional under the trying circumstances of moving new and old appliances up and down several flights of stairs without any damage. In addition they had to get the new air conditioner onto the roof. This was all accomplished in a long day. Their cleanup was amazing. Now that job has been taken care of, I am turning my mind to the old hot water heater - also on the 4rth floor and hence a source of concern. I have now initiated the purchase of a tankless water heater. Given my recent experience with installation of the furnace and AC , I am sure I am making the right choice
