PECO customers: check peco.com for current heat pump rebates.
Some cities bury their heat pump buyers in incentive layers. Philadelphia is not one of them, and pretending otherwise is how buyers here get burned. This guide lays out exactly what is real for Greater Philadelphia and why in this market the sizing and the operating math, not the rebate line, decide whether the project pays.
The Structure: Utility-Driven, Nothing Above It
Start with the shape of the thing. Pennsylvania is utility-driven: there is no state heat pump program sitting on top, so the incentive question reduces to a single question about your electric bill. A homeowner claims their own utility's program, not a menu of them.
For nearly all of the Greater Philadelphia carve, Philadelphia proper plus Bucks, Montgomery, Delaware, and Chester counties, the answer on the bill is PECO. Terms live at https://www.peco.com/ways-to-save/for-your-home/rebates-discounts/heating-cooling-rebates. A quote still carrying a closed PECO heat pump rebate is recycling a closed figure.
Confirm the Current Page, Not a Memory
Pennsylvania utility efficiency programs run in multi-year cycles under Act 129, and Phase IV closed May 31, 2026. The correct posture is still: confirm the current terms the week you sign, and get the quoted tier in writing. "It usually works out" is not an answer; it is a warning.
What That Means in a Table
| Layer | Philadelphia status in 2026 |
|---|---|
| Pennsylvania state program | None exists; the state layer is zero by design |
Read that table cold and the conclusion writes itself: the swing between a well-run Philadelphia project and a badly run one is not the rebate.
Where the Real Money Hides
So where does a Philadelphia buyer actually win? Three places, in order.
First, sizing. The city's rowhome stock, Fishtown, South Philadelphia, Point Breeze, shares walls on both sides, which slashes the true heating load. Philadelphia's winter climate is cold, and a room-by-room load calculation against that number, party walls included, routinely lands a full ton below what a rule-of-thumb quote proposes. The mechanics are in our equipment guide.
operating economics. That is a rebate that renews itself, worked in full in our oil comparison.

The Stale-Quote Test
The rebate landscape hands Philadelphia buyers a beautiful vetting tool: the quotes themselves reveal who is current.
A bidder who quotes a Pennsylvania state rebate fails, because there is none. And a bidder who writes a closed PECO heat pump rebate into the price is quoting a closed figure. The rest of the vetting sequence is in our contractor guide.
A rowhome
A Fishtown rowhome, two stories, 1,100 square feet, gas boiler and window units. Party walls on both sides drop the real load to what a modest two-or-three-head ductless system carries comfortably on a cold night. Priced bands for every pattern are in our installation cost guide.
A project that only pencils if the rebate lands is a project priced wrong for this market.
The Efficiency Tier Is Still Worth Specifying
Specify the higher-efficiency machine in the contract because it is the machine that holds capacity on the coldest nights and dehumidifies properly in July, which is the machine worth owning in this climate anyway. The house still receives that machine whether or not a rebate confirms.
The wrong move is buying down to a cheaper, lower-tier unit to chase a closed PECO amount that the live page no longer prints. That trades a decade of performance for a number that is not on the current PECO page.
What Oil Households Should Hear Differently
For the oil-heated stock in the ring around the city, this entire rebate discussion is a footnote, and that deserves saying plainly. Households in Drexel Hill or Mount Airy waiting for rebate clarity before replacing a dying oil burner are waiting for the small number while paying the large one. Run the delivery-receipt math first; the rebate, if it confirms, is a pleasant afterthought.
The Short Playbook
- Confirm PECO is your utility; in this carve it almost always is.
- Ask every bidder for the current PECO air-source heat pump amount in writing, and refuse any quote still carrying a closed PECO heat pump rebate.
- Demand a room-by-room load calculation on a cold night with party walls counted.
- Run the operating math for your current fuel; for oil homes it dwarfs the rebate.
- Price the project to stand without the rebate, and treat a confirmed rebate as the bonus it is.
