I'm new so I apologize if this has been asked before. Thanks for the great info on your site - I have learned a lot already.
I'm shopping for a new furnace and air conditioner - I've found a recommended, reputable contractor with excellent warranties and prices good too (i've read your posts about excellent contractor being even more important than product).
My house is a small bungalow, about 900 square feet.
I'm looking at a high-efficiency furnace as I live on the Prairies in Canada - many months of extreme cold during the winter. Energy efficiency is important to me. I'd also like to add central air conditioning - I've been told a SEER of 10-11 will be fine here as we don't deal with the months and months of heat like some southern states do. But we usually do have enough really hot days each year to make it a nice luxury here!
I' ve learned on your site that the choice between single stage and double stage furnace is about comfort not efficiency. But I'm not sure exactly what a variable speed blower does? Is a variable blower even available on the single stage furnace? I think I've read that I should consider one because I will also be getting air conditioning and then it adds to the efficiency?
The furnaces I'm looking at are the Rheem Classic 90 Plus single or two stage furnace with Dual Comfort Control. The air conditioner I'm considering is the Trane 1 1/2 ton XR11. But I'm really interested in your answers about whether I should be looking at single or two stage furnace, and whether the variable speed blower is an issue in terms of efficiency.
This is all pretty new to me. Thanks for your help.
