This has been great information - Thank you!!
I have one more question - I have a single stage Thermostat right now and am thinking about getting a 2 stage. I am sure the A/C is single stage - I assume this will work for both the 2 stage furnace and the single stage A/C but I could not find any info confirming this.
Do you know which thermostat would work best - I found the Honeywell T8000 for $120 - is this a good deal?
