I posted earlier concerning my search for a new gas furnace and heat pump to replace my aging furnace and A/C. What advantages do a variable speed furnace offer vs. a 2 stage furnace? Plus are there any differences between Carrier and Trane products?
I live in Omaha, NE and have a 2 story house with 1600 sq ft above grade + a finished basement. HVAC reps have recommended 90K - 100K BTU furnaces w/ 3 ton heat pumps.
Thanks for your help!
