- What does 97% AFUE mean?
- It means about 97% of the gas burned becomes usable heat, with the rest lost through the flue. That puts it among the most efficient gas furnaces available and means it vents through PVC pipe rather than a metal chimney.
- What size home does 80,000 BTU heat?
- Roughly a mid-size home in a cold climate, but the right size depends on square footage, insulation, windows and ductwork. A load calculation from your contractor decides whether 80,000 BTU fits.
- Does it work with R-32 refrigerant?
- Yes. It is designed for use with R-32 systems, so it can pair with a matching R-32 air conditioner or heat pump coil.
- Can I install it myself?
- No. It is a gas appliance that needs proper venting, gas piping, electrical work and a load calculation. Hire a licensed HVAC contractor.
- Can it be installed in California or Colorado?
- No. State rules there require Ultra Low NOx or Low NOx gas units, and this furnace cannot be shipped to or installed in either state.
- What thermostat do I need for full modulation?
- A two-stage or communicating thermostat that supports modulating operation. A basic single-stage thermostat limits how finely the furnace can adjust output.
