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

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 oil, propane, and natural gas systems.

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

Rebates, Incentives, Utility Discounts, & Solar Savings Programs. Since heat pumps are more environmentally friendly than traditional heating systems, the State of Maine and the federal government offer incentives for heat pumps. Learn about rebates, incentives, and other ways to save.

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.

How much does it cost to install a heat pump?
The cost of installing a heat pump system in Maine varies depending on the square footage of the space you want to heat and air condition. Some customers may only need one or two units, whereas others may want to outfit their whole home with heat pumps. In addition, some units may be more energy efficient than others and may cost more, but they often pay for themselves by lowering energy costs and through tax incentives and rebates. Costs to install a single heat pump can start around $4,000, while whole home solutions can start around $15,000. Each home is unique, which is why our consultants will come to your home, listen to your goals, measure your spaces, answer all of your questions, and will deliver a custom quote to your email. Ultimately heat pumps are one of the best investments homeowners can make in the efficiency, comfort, and value of their home.
