Are there any quality single stage VS furnaces on the market? I don't really need a 2 stage, I'm quite comfortable with one, but I do run my fan on low 24/7. In Toronto, where gas is more than 10 cents, that is costing me $450.00 a year. I got the AMPS from the blower, figured out the watts and did the math! YIKES! For that, there is no question that my new furnace with be a VS.
So, why are single stage VS so rare? Or is it just that I'm looking in the wrong place?
