Premium efficiency furnaces can reduce your home energy costs and improve comfort. Installation of these systems does not require a Department of Energy approved tax credit technician. Be sure the system you install meets the eligibility requirements for each technology below.
Forced Air Furnaces
Use the charts below to calculate the tax credit based on the year the equipment was installed.
All installations must meet the following minimum requirements:
- Have an Annual Fuel Utilization Efficiency (AFUE) of 95 percent or higher.
- Has an electrically-efficient fan motor - listed in the Air Conditioning, Heating, and Refrigeration Institute (AHRI) with the "e" symbol. These are typically marketed as "variable speed" blowers. Multi-speed and single speed motors are not electrically efficient.
- System must be installed with ducted outdoor air for combustion. Models that can be installed using either inside or outside combustion air should indicate on the final invoice that the installation was outside combustion air ("two-pipe"), including furnaces installed in garages.
Newer qualifying models may be released and listed in the AHRI directory. Look for the "e" on the certificate after choosing "AFUE/AMACF" from the "Eligible for Federal Tax Credit" drop-down menu on the lower right section of this page:
Note: in "dual fuel" or "hybrid" systems with a gas furnace installed as a backup to a heat pump, only the primary heating system will be eligible for a tax credit.
