Commercial Heat Pump Systems

Southern Maine Heat Pumps designs and installs commercial heat pump systems for offices, retail spaces, warehouses, and multi-unit buildings throughout Southern Maine. Our commercial solutions reduce operating costs, improve employee and tenant comfort, and help businesses meet sustainability goals. We work around your schedule to minimize downtime and deliver systems engineered for the demands of commercial spaces.

Business owners across Cumberland County are discovering that commercial heat pump systems deliver dramatic reductions in heating and cooling costs while improving comfort for employees, customers, and tenants. Whether you operate an office building on Congress Street in Portland, a retail storefront in Gorham Village, a warehouse in Westbrook, or a multi-unit apartment complex in Scarborough, Southern Maine Heat Pumps has the expertise to design and install a system engineered for your specific commercial environment. We understand the demands of commercial spaces, where consistent temperatures, quiet operation, and reliable performance are not optional but essential.

Our commercial solutions range from light-commercial ductless systems for individual offices and shops to Variable Refrigerant Flow (VRF) systems that serve entire buildings with independent zone control for every tenant or department. VRF technology is particularly well-suited for Cumberland County's mixed-use buildings, where a restaurant on the ground floor may need cooling while the offices above require heat. We handle all code-compliance requirements, permitting, and utility coordination so you can focus on running your business. Commercial energy incentives and Efficiency Maine programs can offset a substantial portion of your investment, and we guide you through every available dollar.

In addition to commercial installations, we provide residential heat pump installation for business owners who want to bring the same efficiency home. Our multi-zone heat pump systems are ideal for properties that straddle the line between residential and commercial use, such as bed-and-breakfasts and home offices. Once your commercial system is installed, our preventive maintenance plans protect your equipment, minimize downtime, and keep energy costs as low as possible year after year. If you are replacing an aging rooftop unit or boiler, our replacement and upgrade services ensure a seamless transition.

What Our Customers Say

Don't just take our word for it. Here's what homeowners across Southern Maine have to say about our work.

The crew installed heat pumps with 3 heads and a hot water heat pump and did an excellent job. Very responsive in getting a quote quickly and answered all questions about the process. Very friendly and did an awesome job explaining how to run the heat pumps after installation. Definitely recommend!

I HIGHLY recommend Southern Maine Heat Pumps! Sam and Chris came to provide recommendations and pricing, responded promptly and thoroughly to follow-up questions, installed in a timely manner, got everything installed and tested with a tutorial on how to use everything. Extremely nice and cleaned up after themselves.

Steve and his team were awesome! They worked on ways to make the exterior tubing less visible, were solutions oriented, fast, and clean. They also helped facilitate Efficiency Maine rebates. I have already referred two friends and highly recommend them.

These guys are knowledgeable, professional, and provide superb and cost-effective service. They made an effort to fit us in before federal tax incentives expired at the end of the year. Could not recommend Southern Maine Heat Pumps more!
