Maine’s Leader in Heat Pumps



Tens of thousands of Maine home and business owners are realizing the many benefits of investing in heat pumps. From energy savings to the benefit of air conditioning, heat pumps are a customizable, noninvasive energy solution, with some units providing efficient heating in temperatures as low as -13 °F.

There Are Options for Every Budget. Whether you want one unit for an office, garage, or basement, or you’re looking to outfit your entire home with heat pumps, solutions can be tailored to your heating and air conditioning goals, budget, and unique home.

Savings. Heat pumps are more efficient than traditional heating and air conditioning systems. Even with rising electrical rates, heat pumps are still more efficient than systems that use oil, propane, and natural gas.

Air Conditioning. Traditional air conditioning methods like window units or portable air conditioners are more expensive and less convenient than heat pumps. As the temperatures rise, heat pumps dehumidify and air condition to help homeowners maintain a comfortable and consistent temperature within their homes.

Rebates & Incentives. Since heat pumps are more environmentally friendly than traditional heating systems, the State of Maine and the federal government offer incentives for heat pumps. In 2023, the federal government announced the Inflation Reduction Act, which offers a significant tax credit to most Mainers. Learn more about the IRA. In addition, Efficiency Maine offers rebates for Mainers of all income types. Learn more about the Efficiency Maine rebates.

Compact & Non-Invasive. With the right installer, heat pump installations can be quick and noninvasive. There are four options for indoor units: traditional high wall units, floor units, ducted, and ceiling cassettes. The last two options offer homeowners are more sleek, compact look with whisper-quiet operation.

Breathe Easier. Heat pumps consistently recirculate the air in your home, purifying and filtering the air you breathe.

Customized Comfort. With multi-zone systems, heat pump owners can experience room-by-room temperature control. For example, a three-bedroom home with one unit outside and an indoor unit in each room allows the resident of that room to define what temperature makes them most comfortable.


Who installs a heat pump system can greatly impact the system’s efficiency and the customer’s satisfaction with performance. Heat pumps are not a one-size-fits-all solution.
