Can I combine utility and state HVAC rebates?

Often, but check each program’s terms for caps and offsets.

Why does the calculator not suggest amounts?

Amounts vary by program and change often. We do not publish figures we cannot source for you.

Do I need pre-approval?

Many programs require it. Check before the work starts.

Rebate stacking calculator: what is left to pay

Type each rebate you have been approved for or quoted. The tool adds them, applies the cap, and flags conflicts.

No 25C counted as nothing after 2025 The 25C credit does not apply to property placed in service after December 31, 2025 (IRS).

The short answer

This rebate stacking calculator adds the HVAC rebates you have been offered and shows the net price left to pay. Type the quoted price and each program’s amount from its own terms.

The tool caps the total at the price and flags common stacking problems. It counts no federal 25C credit: that credit does not apply to systems placed in service after December 31, 2025.

What this assumed

—

Adds what you type and caps it at the price. Not tax advice. HyreHVAC does not administer any program.

Why does stacking need care?

Programs from a utility, a state and a manufacturer can often combine, but not always. Some reduce their award by what another program pays.

Some count only toward the cost left after other rebates. Some require approval before work starts. The amounts you type should come from each program’s own written terms, not from an ad.

Stacking checks

Pre-approval
Several programs pay only if you apply before the install.
Combined cap
Total incentives usually cannot exceed the project cost.
Contractor enrolment
Some programs pay only through enrolled contractors.
Equipment rules
Many require ENERGY STAR or a minimum rating confirmed on the AHRI certificate.
Federal tax credit
25C is gone for systems placed in service after 2025.
