I'm assuming I know the answer to this, but guess what happens everytime I assume??
I'm looking at some Carrier literature and the blower speeds for Infinity 80, Performance 80 and Comfort 80 series are variable(I get what that is) for Infinity, 4-5 for Perfomance and 3-4 for Comfort. Could someone clarify that for me?
I currenty have a 19 year old single stage furnace. 17 years ago when the air conditioner was bought, a 2 speed fan (blower?) was put in the furnace, and it runs 24/7. I love it. I'm looking at a new furnace and air conditioner, and I'm trying to decide if I need a two stage furnace. I'm quite comfortable with the single stage, and besides I wonder if the 2 stage is even smart. When my current blower is on low speed, I can barely feel air coming out of the upstairs supply vents. When the furnace kicks in, the blower speed picks up and it's all good. When a 2 stage is working in first stage, what's the deal with the blower? Is it operating at low speed? Would I be getting enough heat upstairs, where my office is, and where I spend most of my day? Hence we go back to my original question about the 4-5, and 3-4 blower speeds!
Thanks for you insights!
