Who it's for
Heating a home that needs about 77,000 BTU/h of delivered heat, replacing an older gas furnace.
The standout number
AFUE 96.1% — a condensing furnace, the efficient class that needs a PVC flue and a condensate drain.
The catch
A furnace is contractor-installed with a gas line, flue and permit — compare installed quotes, not just the box price.

Rebates & incentives
High-efficiency gas furnaces (95%+ AFUE) sometimes qualify for utility rebates, but the bigger incentive money in 2026 targets heat pumps, not furnaces. The federal 25C credit expired December 31, 2025. Check what applies where you live on our rebates page, and compare a furnace's running cost against a heat pump on our operating-cost calculator.

Frequently asked questions
How efficient is the DAIKIN DD96TN0803BN?
Its AFUE is 96.1%, meaning 96.1% of the gas it burns becomes heat in your home and the rest goes up the flue. At 90%+ it is a condensing furnace — it pulls extra heat from the exhaust, so it needs a PVC vent and a condensate drain.
What does the DAIKIN DD96TN0803BN cost to run?
About $17.48 per MMBtu of delivered heat at U.S. average gas prices, roughly 68% less than electric resistance heat. Your local fuel price changes the number — run it in our operating-cost calculator.
How big is the DAIKIN DD96TN0803BN?
It delivers about 77 MBTUH (77,000 BTU/h) of heat from a 80 MBTUH input. Furnace sizing should follow a Manual J load calculation, not a rule of thumb — an oversized furnace short-cycles and wastes fuel.
Does the DAIKIN DD96TN0803BN have a variable-speed blower?
Yes — it uses an ECM (electronically commutated) blower motor, which uses far less electricity than an older PSC motor and runs quieter at low speed. That lowers the fan's share of your power bill, especially if you run the fan for circulation.
Where can I buy the DAIKIN DD96TN0803BN?
Furnaces are installed by a licensed HVAC contractor, who runs the gas line, sets the venting, pulls the permit and commissions it. Get a few installed quotes and compare the total, not just the equipment price.
