I installed a Quiet Cool whole house fan to save on my cooling bills. Does this qualify for the energy efficient improvement under Main Air Circulating Fan?

Who qualifies to claim a residential energy property credit? Are there limitations? (updated April 27, 2021)

A. You may be able to take these credits if you made energy saving improvements to your principal residence during the taxable year. In 2018, 2019 2020, and 2021 the residential energy property credit is limited to an overall lifetime credit limit of $500 ($200 lifetime limit for windows). There are also other individual credit limitations:

• $50 for any advanced main air circulating fan
• $150 for any qualified natural gas, propane, or oil furnace or hot water boiler
• $300 for any item of energy-efficient building property

The residential energy property credit is nonrefundable. A nonrefundable tax credit allows taxpayers to lower their tax liability to zero, but not below zero.

No, a whole house fan does not qualify as a Main Air Circulating Fan (that is a specialized motor for your furnace).
