The short answer
A PPL heat pump rebate depends on the equipment meeting the program's efficiency tier, being installed by a registered contractor, and an application filed with proof of purchase and installation. UGI runs similar rebates for high-efficiency gas furnaces and boilers. Amounts and rules change, so check the current program page before you sign.
Yes, both utilities serving Mount Joy have offered rebates on efficient heating equipment. PPL Electric Utilities runs energy-efficiency programs under Pennsylvania's Act 129 that have included rebates on qualifying heat pumps, and UGI Utilities offers residential rebates on qualifying high-efficiency gas furnaces, boilers and water heaters. The catch is that eligibility rules, deadlines and amounts change, so the real work is asking the right questions before you sign a replacement contract and checking the current program page yourself.
Which utility's program applies to your house
Start with your bills, not the equipment brochure. In and around Mount Joy, UGI supplies natural gas and PPL supplies most of the electricity, but a few pockets of the region are served by other electric companies, so confirm the name on your electric bill before you count on a PPL program.
The system you are replacing decides the rest. Lancaster County homes heat with electricity (37.2%), natural gas (34%) and fuel oil (13.8%), and each path points to a different program:
- Heat pump replacing a heat pump, common in the Florin Hill homes built after 2000: PPL's program is the one to look at.
- Gas furnace or gas boiler replacement: UGI's residential rebates are the place to start.
- Dual-fuel system (a heat pump paired with a gas furnace): you may be dealing with both utilities and two separate sets of paperwork.
- Oil boiler in a pre-1940 house near Main Street: neither utility rebates oil equipment, but a switch to a heat pump or to gas can bring a program into play, so ask before you choose the fuel.
What PPL heat pump rebates usually depend on
PPL's Act 129 programs have historically tied heat pump rebates to efficiency, not to brand. The outdoor unit and indoor coil or air handler usually need to be an AHRI-certified matched system that meets the program's minimum SEER2 and HSPF2 ratings, the efficiency scales used since January 2023. A condenser that qualifies on its own can fail the test if it is paired with the wrong coil.
Programs have also leaned on participating contractors, an application window that opens after installation, and proof that the home has an active PPL residential account. Ductless mini-splits have sometimes been included as well. If your current heat pump is limping along, it is worth a heat pump repair visit to learn whether you are really facing a replacement decision this season or can plan one for spring.
What UGI gas equipment rebates usually depend on
UGI's residential rebates have focused on high-efficiency gas furnaces, boilers and water heaters. The usual hinge is a minimum AFUE rating set by the program, which in practice means condensing equipment that vents through PVC pipe instead of a masonry chimney. That change matters in older Mount Joy houses where the old furnace shared a chimney with a water heater: the leftover appliance may need a chimney liner, and that work belongs in the quote.
Expect UGI to ask for the AHRI reference number or model numbers, an itemized invoice, the installation date and your UGI account number. When you are comparing furnace and AC installation quotes, ask each contractor to name the exact model and its efficiency rating in writing so you can check it against the program list yourself.
Questions to ask before you sign a contract
- Does this exact indoor and outdoor combination appear in the AHRI directory, and does it meet the current program threshold?
- Does the program require a participating contractor, and is the company doing the work on that list?
- Who files the rebate application, you or the contractor, and what documents will you receive at closeout?
- How many days after installation do you have to submit, and does the program end or change at a set date?
- Is the rebate paid to you, or is it deducted from the contract price?
- Was a Manual J load calculation done, so the equipment is sized for the house and not just matched to the old unit?
- Does the quote include permits, the condensate drain, venting changes and electrical work the new equipment needs?
| Item to confirm | PPL (electric heat pumps) | UGI (gas furnaces and boilers) |
|---|---|---|
| Efficiency standard | Minimum SEER2 and HSPF2 on a matched system | Minimum AFUE set by the program |
| Proof of match | AHRI certificate for the combination | AHRI number or model numbers |
| Account | Active PPL residential account | Active UGI residential gas account |
| Contractor rules | Ask if a participating contractor is required | Ask if a participating contractor is required |
| Deadline | Window after the installation date | Window after the installation date |
The federal tax credit is no longer a sure thing
For a few years, the federal energy-efficient home improvement credit made heat pumps and efficient furnaces easier to justify. Legislation passed in 2025 cut that credit back, and installers are still repeating older advice. Before you build a credit into your budget, confirm its current status with a tax professional or on the IRS website. Keep the manufacturer's certification statement and itemized invoice either way, since a tax preparer will ask for both.
Where homeowners lose a rebate they expected
Most lost rebates trace back to timing. A furnace that quits during a January cold snap gets replaced with whatever is in stock, and nobody checks the program list until weeks later. If your system is 15 to 25 years old, as many Florin Hill furnaces and heat pumps now are, our guide on whether to repair or replace an aging system can help you decide before an emergency decides for you.
The other common miss is an unmatched coil. A contractor swaps the outdoor unit and keeps an old indoor coil, the AHRI combination does not exist, and the application is denied. Sizing errors cost money in a different way, which is why we recommend reading what a Manual J load calculation is before comparing quotes. Homeowners in nearby Elizabethtown run into the same issues with their own post-2000 subdivisions.
Keep a rebate folder
Save the signed contract, the itemized invoice, the AHRI certificate, model and serial numbers, the installation date and photos of the equipment labels. Upload copies the same week the work is finished, even if the deadline seems far off.
From the service calls
Why a rebate table you found online may already be out of date
Pennsylvania's utility efficiency programs run in multi-year phases under Act 129. One phase ended on May 31, 2026 and a new one began on June 1, 2026, and a new phase is when equipment lists, efficiency tiers and rebate amounts tend to change. A blog post or contractor flyer from before that date may describe rules that no longer apply.
The paperwork side is where rebates are most often lost. Before the installer leaves, make sure you have:
- The AHRI certificate for the exact indoor and outdoor combination installed, not just the outdoor model
- The model and serial number of every outdoor unit, since ductless rebates are often counted per outdoor unit
- An itemized invoice showing the installation date, the equipment and the contractor's PA HIC registration number
- Your utility account number exactly as it appears on the bill
- Proof the equipment is ENERGY STAR certified if the program requires it
File promptly, because programs set a deadline after installation. Rebates generally do not apply to new construction, so builders and buyers of brand-new homes should check separately. Our AC and furnace installation page covers what the quote itself should show.
When to call, and what to have ready
If your heat pump or furnace is failing and you want to know whether a replacement would fit a current PPL or UGI program, call (321) 478-0693. Calls are answered 24/7, and we send a local HVAC technician who can diagnose the existing system and give you a price before any work starts. Have the model number of your current equipment and a recent utility bill nearby. Then check the current program page at PPL or UGI before you sign anything.
Quick answers
Can I get a PPL rebate and a UGI rebate on the same project?
Possibly, if the project includes equipment that each utility covers, such as a dual-fuel setup with a heat pump and a gas furnace. Each program has its own application, efficiency standard and deadline, and neither one coordinates with the other. Ask your installer to document both pieces separately and check each program page before you sign.
Do rebates apply if my furnace dies and I replace it in an emergency?
They can, because most programs look at the equipment and the paperwork, not the reason you replaced it. The risk is that emergency installs often use whatever is in stock. If you can, ask for the model and AHRI number before the work starts and confirm it against the current program list the same day.
Does a rebate cover repairs to my existing heat pump or furnace?
Generally no. Utility efficiency programs are built around buying new qualifying equipment, sometimes with separate offers for tune-ups or thermostats when those are running. A repair keeps your existing system going but does not usually earn a rebate. Check the current PPL or UGI program page for any maintenance offers available this year.
