Local Incentives

Gaithersburg, MD Heat Pump Rebates & Incentives

Local and federal incentive programs can significantly reduce the cost of a new heat pump system. Here are the programs available to Gaithersburg homeowners.

Pepco Home Performance

Up to $15,000

Pepco offers rebates for eligible home upgrades, including up to $15,000 for qualifying electrification upgrades such as replacing fossil-fueled HVAC with an electric heat pump. Rebates depend on the project and energy savings.

Eligibility: Applicants must have an active Pepco residential account and live in an eligible single-family home. A home energy assessment is required, and electrification rebates require switching an operational gas-, oil-, or propane-fueled HVAC or water-heating system to electric; rebate reservations must be made by December 31, 2026.

Electrify MC

$1,000 - $2,500

Montgomery County’s pilot provides a direct incentive for qualifying heat pumps that replace fossil-fueled heating. The incentive is applied to the project cost through the county’s selected contractor.

Eligibility: The home must be in Montgomery County with individually metered utilities, and the work must be coordinated and completed by Elysian Energy. Incentive amount and equipment requirements vary by heat-pump type; some systems require that fossil-fuel heating not be retained.

Montgomery Energy Tax Credit

Up to $250

Montgomery County offers a property-tax credit for qualifying energy-conservation devices, including eligible heating and cooling equipment. The annual credit is subject to the countywide funding cap.

Eligibility: The property must be an owner-occupied residence, and the device must qualify as an energy-conservation improvement; replacement heat pumps may qualify when they substantially increase heating-system efficiency. Apply with the required receipt, generally within 12 months of installation; credits are limited to $250 per property per fiscal year and awarded subject to available funding.

Learn more →

Gaithersburg homeowners may be eligible for Pepco electrification rebates, Montgomery County’s Electrify MC incentive, and a county energy-efficiency property-tax credit. Palmetto can help homeowners identify qualifying upgrades, navigate applications, and maximize available incentives.

Incentive information is based on publicly available data as of 2026 and may change. Contact program administrators to verify current availability and eligibility requirements.

Climate Zones

Gaithersburg is in USDA Hardiness Zone 7, with freezing winter stretches and hot, humid summers. Its design heating temperature is 5°F, while its design cooling temperature is 92°F, so heat pumps must be sized and selected to handle both cold snaps and summer heat. Palmetto understands Gaithersburg’s climate and can recommend a system for local conditions. Explore other zones below or enter your ZIP code to confirm yours.

Gaithersburg Electricity Prices

For Gaithersburg homeowners, rising electricity prices make how efficiently a home heats and cools worth a closer look.

Maryland’s average electricity price climbed from 13.1 cents per kilowatt-hour in 2021 to 17.9 cents in 2024, above the 2024 U.S. average of 16.5 cents. Local rates may vary by utility and plan.

By moving heat instead of generating it, heat pumps can deliver roughly two to three times as much heating or cooling per unit of electricity as conventional HVAC systems, helping homes use less power as rates rise.

Over time, using less electricity to maintain comfortable temperatures may help offset higher rates. Actual savings depend on your home, system, energy use, and utility rates, but efficiency can make a heat pump a valuable long-term option.

Gaithersburg Area Utility Providers

In Gaithersburg, Pepco’s 2023 electricity price was 18.2¢ per kWh. 2024 utility data isn’t available yet, so the chart compares this figure with 2023 state and national averages.

Pepco’s price was above Maryland’s 16.60¢ and the national average of 16.0¢ per kWh. These figures show the difference, but not its cause; utility prices can reflect local electricity supply and delivery costs.

A higher electricity rate doesn’t tell the whole heating-cost story. Heat pumps move heat efficiently and may use less energy than traditional HVAC, potentially reducing total energy spending. Actual costs depend on the home and how the system is used.

Repair versus replace

When a heat pump is in need of repair it is worth considering whether a replacement would be a better investment. While each case is unique, we generally recommend investing in a new unit when repairs exceed $5,000.

$5,000
Recommended repair threshold

A heat pump's lifetime is impacted by a number of factors including environment, use and the quality of the unit. It's important to choose the right unit for your climate zone and home's unique attributes.

When you are in need of repair, we recommend choosing a service provider that is an expert in the heat pump brand you have installed, and checking online reviews to ensure you are investing in the right level of service.

Potential repair Cost range Description
Capacitor Replacement $150 - $400 Common issue when unit struggles to start or makes a humming noise. Capacitors store the electrical energy needed to start the compressor and fan motors.
Refrigerant Recharge $250 - $750 Needed when the system loses cooling or heating efficiency due to low refrigerant levels. Includes leak detection, repair of minor leaks, and recharging the system to the manufacturer-specified level.
Reversing Valve Replacement $450 - $900 Required when the unit cannot switch between heating and cooling modes. The reversing valve directs refrigerant flow and is unique to heat pump systems.
Compressor Replacement $1,500 - $3,000 Major repair needed when the unit fails to heat or cool entirely. The compressor is the heart of the system, circulating refrigerant between the indoor and outdoor coils.
Evaporator/Condenser Coil Replacement $1,200 - $2,800 Replacement needed when coils develop leaks or corrosion that cannot be economically repaired. Coil damage reduces heat transfer efficiency and can cause refrigerant loss.
Control Board Replacement $500 - $1,200 Required when the system has electrical failures or erratic behavior. The control board manages all system operations including defrost cycles, fan speeds, and compressor staging.
Full System Replacement $4,500 - $8,000+ When repairs exceed the value of the unit or multiple major components fail simultaneously. Includes removal of the old system and installation of a new heat pump with updated refrigerant lines and electrical connections.

Unlike a furnace paired with a separate air conditioner, a heat pump handles both jobs. Palmetto offers a $0-upfront Comfort Plan with maintenance and repairs, or direct purchase, with ownership and possible state or utility rebates where available.
