Air-source heat pump vs. AC/furnace
I am contemplating some different HVAC options in Connecticut (zone 5). I currently have an 80% efficiency Carrier Infinity NG furnace (8 years old) that can be paired with a Carrier Greenspeed heat pump. I can do that for $11,400 before incentives, or replace my existing and dying 10 SEER AC unit with a new 16 SEER for $8,000.
I can also pair a new AC unit with a high efficiency gas furnace, ranging from $15,000 for Performance level or basic Infinity equipment to $18,400 for equipment with Greenspeed technology. Our current equipment is 5-ton, and our home is 3,500 square feet. We’ve tightened the envelope and insulated up to R-49.
We are in this home to stay, so we can wait for payback to occur. I just don’t know costly it will be to heat our home using an air source heat pump, or how much we’d save going with a higher efficiency gas furnace over keeping what we currently have. Does anyone have any thoughts or suggestions?
