Methodology and sources

Home Incentive Map holds one record per program in programs.json. Each record was read from the program's own web page on the date shown and carries the amount as the page states it, the conditions the page lists, a link to apply and the page's own "last updated" date where it shows one. No amount is estimated, averaged or carried over from another state. The data version is 2026-10-21; this build treats October 21, 2026 as today for open and ended dates.

Scope

The site covers six upgrades: air-source heat pumps, heat pump water heaters, insulation and air sealing, home EV chargers, induction ranges and cooktops, and electrical panel upgrades. It started with the six New England states (read 2026-10-20), where statewide programs cover nearly every household. The national expansion (read 2026-10-21) went through the largest states by population and added a state only where at least one open offer with a published amount could be read from the program's own page: Arizona (SRP), California (SMUD and Golden State Rebates), Oregon (Energy Trust of Oregon); Florida (FPL), North Carolina (Energy Saver North Carolina), Texas (Austin Energy); Michigan (Consumers Energy and MiHER), Wisconsin (Focus on Energy); Pennsylvania (PPL Electric). Outside New England a state's coverage is only as wide as the programs read, and each state page names the utilities whose programs have not been read.

A state-and-upgrade page is built only where at least one open offer with a published amount was found: 49 of the 90 pairs across 15 states. New York, Washington, Colorado and Georgia were read but have no open offer with an amount (their IRA status is on the federal page); the other states are not covered yet.

How amounts are computed

• Flat rebates are shown as written. Per-ton rebates multiply the program's rate by tons (AHRI cooling capacity ÷ 12,000 Btu, as Mass Save, NHSaves and Energize CT define it) and apply the program's cap or ton limit. Per-unit and per-zone rebates multiply by outdoor units or insulated zones and apply the cap. Percent offers need your project cost. Per-square-foot offers take the lesser of the rate times area and the program's percentage of cost.
• Offers stated as "up to" or as a range are counted at their maximum and labelled "max": they are ceilings, not what every project gets.
• Stacking. Offers inside one program (tiers, tracks such as Whole-Home and Partial-Home) are alternatives: only the largest counts. Separate programs add up. The total never exceeds the project cost when one is entered. Where a program page says it cannot be combined (Mass Save water heaters with other Mass Save incentives for the same equipment), the records are in one group.
• Income tiers follow each program's own definition; the calculator's "moderate" and "low" choices select the matching tier, and offers marked income-qualified apply to both.
• An offer whose end date has passed is shown as ended on the next build; the calculator uses the visitor's date.
• Ended pages keep their URL. Every state-and-upgrade URL that has been published is recorded. When all of a page's offers end, the page stays at the same address with an "ended" notice, what the offer paid and where money remains, but it is marked noindex and dropped from the hubs, the sitemap and the calculator links.
• What the equipment replaces. Some offers depend on the fuel being replaced: the heating fuel for heat pumps and panels, the old water heater for heat pump water heaters, the old stove for induction. Worked examples on state pages replace each state's stated example heating fuel, an electric water heater and a gas stove.
• A percentage offer with a cap (for example North Carolina's HEAR at 50% or 100% of cost) needs a project cost; without one it is shown at its cap and labelled "max".

Sources

Utility lists per state come from the sponsor lists on the program pages: Arizona, California, Connecticut, Florida, Maine, Massachusetts, Michigan, New Hampshire, North Carolina, Oregon, Pennsylvania, Rhode Island, Texas, Vermont, Wisconsin.

Left out, and why

• Rhode Island Energy insulation and air sealing. Program pages could not be fetched (the vanity URL redirected to an out-of-state utility); no amount is shown until it is read from the source.
• Rhode Island Energy home EV charger rebates. Program page could not be fetched; left out.
• United Illuminating home EV charger rebates. uinet.com could not be fetched before the research window closed; left out.
• New Hampshire EV charger and induction rebates. No open utility program was found on NHSaves; NHEC and Liberty EV pages could not be fetched.
• Connecticut and Maine induction rebates. Energize CT and Efficiency Maine appliance pages list none.
• Panel upgrade rebates outside Massachusetts. No stand-alone panel rebate was found on the program pages read; HEAR panel rebates are not open in New England.
• Vermont co-op and municipal utility offers (VEC, WEC, Stowe, VPPSA) beyond the Efficiency Vermont list. Their own pages were not read; the site shows only the Efficiency Vermont offers they fund.
• New England Heat Pump Accelerator (NEHPA) instant incentives. nehpa.org publishes no residential amounts; mentioned in text only.
• energy.gov Home Energy Rebates state map. energy.gov/save/home-energy-rebates returned an error again on 2026-10-21; each state office page was used instead.
• Duke Energy (North Carolina) and Georgia Power rebates. Their program pages returned a fetch error; North Carolina is covered through the state-run HEAR only, and Georgia has no page.
• New York (Con Edison, NYS Clean Heat, NYSERDA). cleanheat.ny.gov publishes no amounts without an address, and Con Edison's heat pump page says it has “exhausted funding for air-source heat pump projects”. No open, sourced offer, so no New York pages.
• Washington (PSE, Seattle City Light) and Colorado (Xcel Energy). Searches returned only third-party summaries, not the utility pages; the state HEAR programs publish no amounts (Washington) or are closed (Colorado). Status only, on the federal page.
• Illinois (ComEd, Ameren), Maryland (BGE), New Jersey, Virginia, Ohio, Minnesota and the remaining states. Not read in this wave: the ComEd page is built in the browser and returned no text, and the shared search budget ran out. Not shown until read from the program page.
• Texas, Arizona, Florida, Pennsylvania, Michigan and California utilities other than the ones listed. Only Austin Energy (TX), SRP (AZ), FPL (FL), PPL (PA), Consumers Energy (MI), SMUD and Golden State Rebates (CA) were read. Customers of other utilities in those states see no utility offer here.
• Arizona and Pennsylvania IRA home energy rebate status. The state energy office pages were not reached (Pennsylvania's guessed URL failed; Arizona was not searched before the budget ran out). The state pages say the status was not checked.
• Consumers Energy heat pump water heater and Austin Energy whole-home weatherization. The pages state no dollar amount (Consumers) or only an average rebate (Austin Energy “averaging $3,000”), which is not an offer amount.

Known gaps

Several program pages state an income-qualified bonus without an amount (Efficiency Vermont heat pumps), describe a pilot without amounts (Rhode Island HEAR), or publish conflicting dates (National Grid's EV wiring deadline). The site quotes what the page says and does not fill the gap. Federal Inflation Reduction Act rebate caps appear only where a state page publishes them (New Hampshire), and only as planned amounts.

Refresh

Programs reset each January and can change mid-year. The refresh script re-reads every source page, flags any page whose text changed since the last check and any offer whose end date has passed, and a record is updated only after a person reads the changed page.
