Maryland Heat Pump Rebates

Montgomery County, Maryland

Replacing your heating system in Montgomery County? Check your rebate options before you sign.

Rebates in Montgomery County come from the electric utility on your bill, and most are paid through the contractor. Once a contract is signed or a system is installed, it can be too late to fix a missed step. Pick your utility to see each offer, what to confirm before you sign, who files the paperwork, and the official page. Nothing to sign up for.

Which electric utility is on your bill?

Look at the company name at the top of your electric bill. Ignore any separate "supplier" you buy power from: rebates come from the utility that delivers it, whatever your supplier. In Montgomery County that is usually Pepco. The Maryland Office of People's Counsel says Pepco serves most of the county, and BGE and Potomac Edison serve parts of it.

My AC needs replacing. Can I get a heat pump and keep my furnace?

Often, yes. If your home has a gas furnace and a central air conditioner and the AC fails, you usually have three choices. Each one changes your rebate, so decide before you sign.

1. Replace the AC with a new AC, keep the furnace

The smallest change. Pepco and Delmarva list a central AC rebate of $300 (Tier 1) or $500 (Tier 2), and Potomac Edison lists up to $1,400. BGE's heating and cooling table doesn't list a central AC rebate. You keep heating with gas.

2. Replace the AC with a heat pump, keep the furnace as backup

Often called a hybrid or dual-fuel system. The heat pump cools in summer and heats most of the winter, and the furnace takes over when it's very cold. The rebate is the part to pin down. Potomac Edison says its Switch-to-Electric program pays lower incentives for this kind of partial switch. Pepco, Delmarva and BGE pay one amount for replacing electric equipment and a higher one for switching off gas, oil or propane, and their pages don't say which applies when you keep the furnace. For whole-home (Home Performance) rebates, the higher $15,000 cap is for projects that switch a gas, oil or propane furnace, boiler or water heater to a qualifying heat pump.

3. Replace both with an all-electric heat pump

The furnace comes out. This is the case the higher "switching" amounts are written for. At Pepco and Delmarva, the higher air-source amounts are for installs completed by November 30, 2026. It may need electrical work, and a heat pump sized for heating can be larger than the AC it replaces.

Ask the contractor, and get the answers in writing
  1. If I keep my furnace, which rebate line do I qualify for: the regular amount, the switching amount, or none? What dollar amount goes on my quote?
  2. How old is my furnace, what shape is it in, and is it worth keeping for the life of the new heat pump?
  3. At what outdoor temperature will the furnace take over, and who sets that on the thermostat?
  4. Will the new indoor coil and the furnace's blower work together, or does more need replacing?
  5. Will you do a Manual J load calculation so the heat pump is sized for heating, not just cooling?
  6. Will the job be finished before my utility's deadline, and who files the paperwork?

General guidance, not a program rule: which option costs less to run depends on your house, your equipment and your gas and electric rates, so we don't guess.

For the biggest rebates, start with a home energy assessment.

A participating contractor checks your whole house and shows where it wastes energy. It's required for whole-home rebates of up to 75% of the project (up to $15,000). It costs $100 at BGE, Pepco and Potomac Edison, or nothing for eligible lower-income households. Why it comes first →

Why the energy assessment comes first

A home energy assessment (sometimes called an energy audit) is a visit from a trained participating contractor who checks the whole house, not just the furnace. It's the step most people skip, and skipping it can cost the most.

1. It's the key to the biggest rebates

In Maryland, whole-home rebates of up to 75% of the project, up to $15,000 when you switch from gas, oil or propane, start with the assessment. Your rebate is based on the savings the contractor calculates from it. No assessment, no whole-home rebate.

2. It finds where your money leaks out

Pepco describes it as a "comprehensive evaluation of your home systems (air sealing and insulation, HVAC, and more) to identify where energy is being wasted." You get a detailed report with recommended fixes and the rebate for each one.

3. It can make your heat pump smaller and cheaper

General guidance, not a program rule: a house that leaks less heat needs less heating. Sealing and insulating first can mean a smaller heat pump that costs less to buy and to run, and keeps rooms more even. That's why BGE requires attic air sealing and insulation before heat pumps count toward its whole-home rebate.

4. It costs little, or nothing

BGE and Pepco each charge $100 for the assessment, which they call "a $400 value." Lower-income households may get it at no cost: Pepco offers a Moderate Income option, and BGE says eligible customers can get the audit "at no additional cost."

Questions to ask the assessor
  1. Will you measure how much air the house leaks, for example with a blower door test?
  2. Which fixes come first, and what is each one's rebate?
  3. What size heat pump would the house need after sealing and insulation?
  4. Can you submit my reservation before December 31, 2026?

Whole-home rebates: how "up to 75%" works

BGE, Pepco and Delmarva's Home Performance with ENERGY STAR programs pay a share of a whole-home project: air sealing, insulation, and often a new heat pump. Here's the rule, in each utility's own words:

"Rebate amount based on modeled … savings up to $10,000 or 75% of total project cost; up to a maximum of $15,000 or 75% of job cost if your project includes switching a combustion-fuel furnace, boiler, or water heater to a qualifying electric heat pump."

In plain words:

  • 75% is a ceiling, not a promise. Your rebate is based on the energy savings your contractor's software calculates, and it can't go above 75% of the cost or the dollar cap, whichever is lower.
  • The cap is $10,000, or $15,000 if you switch a gas, oil or propane furnace, boiler or water heater to a heat pump.
  • To reach the full $15,000, the project has to cost at least $20,000 (75% of $20,000 = $15,000). You'd still pay at least $5,000 yourself.
Before you count on it
  • It starts with a $100 home energy assessment (a $400 value) by a participating contractor.
  • Deadlines: the contractor must get an approved reservation and submit the completed project by December 31, 2026. Pepco also requires the approved work to be finished within 90 days of the reservation approval. Later projects wait on a Public Service Commission decision about 2027.
  • BGE: for heat pumps, water heaters and windows to count, the project must include attic air sealing and attic insulation (R-49).
  • Who qualifies: Pepco and Delmarva say single-family homes, townhomes, row homes and 1–4 unit homes, not condos or apartments. Renters need the landlord's written permission.
  • Potomac Edison runs its own Home Performance program: 75% of eligible costs up to $10,000, or up to $14,500 when switching fuels, plus up to $3,000 for electrical work (checked Nov 7, 2026). SMECO's whole-home program wasn't checked. Ask SMECO directly.

Could you get upgrades at no cost?

Maryland's EmPOWER Limited Income program, run by the Department of Housing and Community Development (DHCD), installs energy upgrades at no charge for eligible households. Check the income limit for your household size.

You're also automatically income-eligible if you currently take part in programs such as SNAP, Medicaid, SSI, TANF, HUD housing assistance, utility bill assistance through OHEP, and others on DHCD's full list. The program may provide insulation, hot water system improvements, furnace cleaning, tuning and safety repairs, and health and safety items. Ask DHCD what it can do for heating equipment in your home.

Do I need a new system?

Eight quick questions. We'll show you which answers matter and why. This helps you decide what to ask. It isn't an inspection: only a technician who sees your equipment can diagnose it.

The road, in order

Most lost rebates come from doing things out of order: buying first, then learning the program needed an assessment or a participating contractor.

  1. 1

    Book a home energy assessment

    In Maryland, this is the first real step. It shows where your house wastes energy, and it's required for the biggest rebates: up to 75% of the project, up to $15,000. BGE and Pepco charge $100, or nothing for eligible lower-income households. Why it matters →

  2. 2

    Know your utility and its deadline

    Pick the company that delivers your power, not your supplier. Whole-home projects need a reservation by December 31, 2026, and BGE and Potomac Edison need HVAC installs done by then.

  3. 3

    Check your current system

    Use the eight questions above. Planning before something breaks gives you time to use rebates properly.

  4. 4

    Seal air leaks and add insulation

    A tighter house needs a smaller system. BGE requires attic air sealing and insulation before heat pumps count toward its whole-home rebate.

  5. 5

    Size it right

    Ask for a Manual J load calculation. It tells you what size system the house actually needs.

  6. 6

    Install with a participating contractor

    Maryland's rebates are paid through participating contractors. A non-participating installer can cost you the rebate. Get two or three quotes.

Five questions to ask every contractor
  1. Are you a participating contractor in my utility's program right now?
  2. Which tier does this model meet (SEER2 and HSPF2), and what rebate does that give me?
  3. Will you do a Manual J load calculation before you quote a size?
  4. Will the job be finished before my utility's deadline?
  5. Who files the rebate paperwork, and is the rebate taken off my price or paid to me later?

Questions Marylanders ask

Which utility serves Montgomery County?

Mostly Pepco. The Maryland Office of People's Counsel says Pepco serves most of Montgomery County, and BGE and Potomac Edison serve parts of it. The company name at the top of your electric bill is the one that counts. If you also have gas service, it's often from Washington Gas, but heat pump rebates come from the electric utility.

I buy my power from a different supplier. Can I still get rebates?

Yes. Rebates come from the utility that delivers your power, not the supplier. Pepco's page says "All Pepco residential electric customers are eligible, regardless of your electricity supplier," and BGE's says its customers are eligible "regardless of your electricity and/or natural gas supplier."

Do I have to fill out rebate forms myself?

Usually not for the heat pump itself. Pepco and Delmarva pay heat pump incentives through participating contractors and distributors, BGE shows its rebate in the contract price, and Potomac Edison and SMECO discount equipment through participating contractors. For whole-home rebates, the contractor submits the reservation and completed application. The Pepco heat pump water heater rebate is the exception: you mail it in yourself.

Can I get both the "efficiency" and the "switching" amount?

No. Utilities list two different offers. You get the one that matches what you're replacing: the switching (electrification) amount if you're moving off gas, oil or propane, and the efficiency amount if you're replacing electric equipment.

What are Tier 1 and Tier 2?

Efficiency levels set by each utility using the equipment's SEER2 (cooling) and HSPF2 (heating) ratings. Higher-rated equipment reaches Tier 2 and earns more. Your contractor can tell you which tier a model meets.

What happens after December 31, 2026?

As of November 7, 2026, BGE and Pepco say they're waiting on a Public Service Commission decision about extending programs into 2027. Amounts and rules could change. We'll update this page when the decision is published.

Is the federal tax credit still available?

No. The federal 25C credit doesn't cover heat pumps placed in service after December 31, 2025. Utility and state programs are what's left.

Why don't you show my total savings?

Because the honest answer depends on your house, your equipment and your energy prices. A guessed number can cost you money. We show the official rebate amounts and deadlines, with the date we checked them.
