If your electric bill says PECO, which for Greater Philadelphia it almost certainly does, this page is the program layer of your heat pump project. It is also, in 2026, a page that has to be honest about timing: Pennsylvania's utility efficiency programs run in phases, a phase boundary just passed, and the difference between a current contractor and a stale one is whether they acknowledge it. Here is the full picture, the tier logic, the phase question, and the exact way to protect a project that spans the transition.
What PECO Has Paid
PECO's residential program has paid tiered rebates on qualifying air-source and ductless heat pumps, scaled by efficiency level, ranging up to about $1,950 at the top tier. The structure rewards better equipment: the higher the efficiency of the installed system, the larger the check. Program terms live at peco.com.
Two structural facts frame everything else. First, this is the only incentive layer in the region: Pennsylvania runs no state heat pump program above it, and the federal 25C credit expired December 31, 2025, so the PECO line is the whole rebate conversation. Second, you claim your own utility's program; a homeowner in this carve deals with PECO, period.
The Phase Question, Plainly
Pennsylvania utility efficiency programs operate under Act 129 in multi-year phases, and Phase IV closed May 31, 2026. What Phase V offers for heat pumps, at what tiers, from what date, is the question every 2026 quote in this region must answer before a rebate line means anything.
This is normal program mechanics, not a scandal. Phases end, successors follow, terms shift. But it creates a very specific 2026 trap: a contractor quoting "the PECO rebate" from memory of the closed phase, on a project installing after the boundary, is quoting money that may not exist on your timeline.
How to Protect the Project
The protection is procedural and cheap:
- Ask the bidder, first call: which Act 129 phase does the quoted rebate ride on, and is the program accepting applications for my install date?
- Require the answer in writing on the quote: program name, tier claimed, and confirmation date.
- Check peco.com yourself the week you sign; program pages state current availability.
- Price the project to stand without the rebate, treating a confirmed rebate as upside.
- If the rebate is real at signing, submit promptly; tiers and budgets are program-year creatures.
That fourth rule deserves its own sentence: on a five-figure Philadelphia install, about $1,950 at best is worth collecting but should never be load-bearing. The projects that go wrong here are the ones that only penciled with the rebate in.
Why the Tier Structure Rewards Good Buying
Look past the timing question and PECO's tier design carries a useful signal: it pays the most for the highest-efficiency equipment, which is the equipment a Philadelphia buyer should want anyway.
The same variable-speed, high-efficiency machines that top the tier tables are the ones that hold capacity at the city's 12F design night and dehumidify properly in July, per our equipment guide. So the rebate, when live, functions as a discount on the right decision rather than a bribe toward the wrong one. Specify the efficiency tier in the contract either way; if Phase V pays on it, the paperwork is ready, and if not, the house still got the better machine.
The Stale-Contractor Tell
The phase transition hands buyers a vetting tool sharper than any review site. Sort your bidders by their rebate talk:
A bidder quoting the federal tax credit is a year out of date; that ended December 31, 2025. A bidder quoting a Pennsylvania state rebate is inventing a program that does not exist. A bidder quoting a PECO number with no phase language is running on autopilot. And a bidder who raises the Phase IV closure unprompted, explains what needs confirming, and prices the project to stand alone has just demonstrated they read program bulletins the way good contractors read code updates. That correlation is the whole reason the contractor guide exists.
Where the Bigger Money Was All Along
Keep the rebate in proportion. For the oil-heated homes ringing the city, the operating swing from oil to a cold-climate heat pump runs $1,000 to $2,000 a year, renewing annually, several times any one-time rebate, worked in our oil comparison. For rowhome buyers, party-wall sizing discipline is worth more than the top tier. The rebate is the garnish on a project whose main course is sizing and operating math, which is exactly how our rebates guide frames the whole landscape.
The Paper Trail That Collects
When the program is live, the application is not complicated, but it punishes disorder. Build the folder as the project runs: the quote showing the efficiency tier, the equipment submittal sheets with model numbers, the invoice marked paid, and the installer's information. Rebate applications draw on all four, and reconstructing a submittal sheet three months after install is the kind of chore that turns a real rebate into an abandoned one.
Two timing habits help. Submit within days of commissioning, not months, because utility program budgets are annual creatures and early applications meet full coffers. And keep the confirmation number; utility processing takes weeks, and the number is the difference between a status check and a restart.
If the Bill Does Not Say PECO
A brief note for the carve's edge cases. Pennsylvania's other utilities run their own, smaller programs: PPL Electric has paid up to $450 on qualifying heat pumps, FirstEnergy's operating companies around $500, Duquesne Light around $200, each under the same Act 129 phase mechanics and each claimed only by that utility's own customers. If a property at the fringe of the region bills through one of these, the playbook is identical, confirm the phase, get it in writing, price the project to stand alone; only the number on the check changes.
The One-Paragraph Summary
PECO is the region's only heat pump rebate layer; it has paid tiered rebates up to about $1,950 by efficiency; Act 129 Phase IV closed May 31, 2026 and Phase V terms must be confirmed at quote time; the confirmation belongs in writing on the quote; and the project should pencil without it. A buyer who holds those five facts cannot be sold a stale number.
And a final calibration for anyone comparing notes with a neighbor's 2024 project: their net price likely included a federal tax credit that no longer exists, having expired December 31, 2025. Your arithmetic is different, not worse; the machine's operating savings never expired, and the sizing discipline in our equipment guide was always the bigger lever.
