Heat pumps in Pennsylvania
Pennsylvania has the highest heat pump adoption in the Northeast at 8.4% of homes — helped by a big share of housing that never had gas mains and went electric decades ago. It is also the state where finding a rebate takes the most work, because there is no single statewide program.
Heat pump adoption
EIA RECS 2020 microdata ↗8.4% of Pennsylvania homes use a heat pump as their main heat
Goal: every home
Central heat pumps and ductless mini-splits combined, counted as the home's main heating equipment. A further 1.8% of Pennsylvania homes run a mini-split as secondary heat alongside natural gas or propane.

Money and next steps
What Pennsylvania pays toward one
Penn Energy Savers
Pennsylvania has no single statewide residential efficiency program — utility programs run separately under Act 129. The state's IRA-funded rebates are being set up by DEP under the Penn Energy Savers name; check the launch status before planning around them.
Program details →Federal Home Energy Rebates
The IRA rebate programs (HEAR and HOMES) survived the 2025 tax changes — they were grants to states, not tax credits. Each state runs its own, and they are at different stages: some open, some already out of money, some yet to launch. Check where Pennsylvania stands before you count on it.

The federal 25C tax credit — 30% back, up to $2,000 on a heat pump — ended for systems placed in service after 31 December 2025. If you had one installed in 2025 or earlier you can still claim it; there is no successor credit. Incentives move fast, so check DSIRE for what is current in Pennsylvania.

Cold-climate heat pumps are rated to hold full output well below zero. The question here is not whether one works, it is whether yours was sized and installed for the coldest night of the year rather than the average one.
