I live in the Chicago area. My Trane furnace is now 23 years old and I've never had to have a service call, however, currently although off, there is a humming sound now and then apparently caused by an electrical connection.
Because of it's age I have decided to replace the furnace and air conditioner. I live in a condo town house which limits me to using only an 80 rather than a 90 or 95% unit because of the venting.
I mentioned where I live because despite the cold winters, I keep my thermostat between 62 and 65. Knowing that, should I purchase a single or double stage furnace. My current furnace is single stage.
If I were to go to a 2 stage, how many years would it take to make up the cost difference between a single and 2 stage?
Please help
