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.

Justin Spear

“I had neglected annual service out of fear that it would cost a fortune but when I called to make the appointment, they let me know what was included in service and the cost- amazing! I appreciated that they were willing to service the system even though they did not do the installation.”
Ben Winkler

“I contacted Southern Maine Heat Pumps to service my two units. The technicians who came out to service our heat pumps did an outstanding job. They were very thorough and helpful. They did a way better job than what I have experienced before with other maintenance services.”
Matt Heer

“The technician arrived right on time, diagnosed the issue quickly, and had both of my heat pumps running smoothly in no time. They explained everything clearly and didn’t try to upsell unnecessary services — just honest, quality work. The price was fair, and the customer service was exceptional.”
Sarah McKay

“I was being serviced by another local company as I had a crack in my Daikin Drip Pan. The previous company came out 3 times and finally diagnosed it. They ordered the part and then never showed up again even though the part was under warranty. I found Southern Maine on a google search and gave them a call. Sam called my back immediately.”
