I'm replacing a 30 year old furnace to increase efficiency
before the rates go through the roof.
I've had 4 bids, each with a different brand. I chose these installers based on reputation and ability, as it's noted repeatedly here that's the most important consideration.
One guy I scratched off because he spent only 5 minutes total in the house, and tried to get my decision that night.
The other 3 seemed to put considerable thought into everything and answered any questions I had.
They've all agreed that the 90 % is the way to go, based on everything.
My quesion is: I can get a 90% single stage or 90% 2 stage.
What would be the difference besides comfort, which I've seen in another post? Would a 2 stage produce a noticeable increase in my electric consumption if it does not have an ECM motor?
The offered 2 stage has a 10/10 warranty while the single has a 5/5.
Thanks.
This is a great site for those of us that know nothing about the industry.
