What this means…
Rebates are based on the size of the heat pump system, measured in tons (a standard HVAC unit — 1 ton equals about 12,000 BTUs per hour of heating or cooling capacity, typically enough for roughly 500–600 square feet, depending on the home).
For 2026, many utility programs have adjusted their incentive levels:
Whole-home systems (where the heat pump serves as the primary heating system) typically qualify for about $2,650 per ton, up to a maximum of $8,500.
Partial-home systems (supplementing an existing heating system) generally qualify for about $1,125 per ton, up to $8,500.
Income-qualified households may be eligible for enhanced rebates of up to $16,000, sometimes covering most or all of the installation cost, depending on program rules.
In addition, federal incentives have shifted in 2026 from tax credits to point-of-sale rebate programs for income-eligible households.
Bottom line: the larger your system (in tons), the higher your potential rebate — up to the program’s maximum cap.
