I am installing a suite in my walk-out basement and regulations require that the suite have a separate furnace, or a zoned furnace, with a zone dedicated to the suite, and at least one other zone dedicated to the rest of the house.
I decided to go with the zoned furnace option. The existing furnace in the house was a mid-efficiency model, and was significantly over capacity for the house. The result of this over-capacity was the development of 'hot spots' in the heat exchanger. Left alone, Manny tells me, these hot spots can eventually burn right through causing the leakage of carbon monoxide into the house. Not a good thing!! So I retired that furnace!
Manny correctly sized a replacement furnace, and because of the size of the house, went with three zones, one for the basement suite, one for the non-suite area of the basement, and one for the main floor of the house. I now have what I regard as a sophisticated heating system that delivers separate controllable heating to all parts of the house.
What I regard as equally good about the furnace installation is that the heat vents in the basement were installed taking advantage of the raised wood foundation in the house. In other words, Ed was able to go down into the crawl space and install heat runs to all parts of the basement and basement suite. He got into places that I certainly cannot get into!
The result of this floor level heat venting in the basement is that the heat in the basement circulates properly, instead of entering the space at ceiling level, and staying up there, creating hot heads and cold feet! Not good!
Manny also installed a new humidifier on the furnace, and installed a sensor on the outside of the house that measures ambient temperature outside, and then automatically sets the humidifer appropriately. Too much moisture is too much of a good thing!
Another positive thing about using Comfortable Home Systems is the fact that Manny can do the gas fitting necessary, and can also do any plumbing required. I contacted other firms for quotes, and in at least one case the company would have had to bring in another trade for one or more of these functions. Up goes the price!
I now have what I regard as a high quality living space in the basement, on par with main floor living.
Bottom line: Manny is very honest and reliable - what he commits to is what he does. And he and his crew do it all cheerfully and on time!
