Heat Pump Installation in Portland, ME
Expert heat pump installation and service in Maine's largest city. From the Old Port to Deering to the Islands, we deliver year-round comfort for Portland homes.
As Maine's largest city, Portland presents unique opportunities for heat pump installation and energy efficiency upgrades. From the historic Victorian-era homes in the West End to modern condos along the waterfront, Portland's diverse housing stock benefits enormously from ductless mini-split and multi-zone heat pump systems. Many Portland homes were built before central heating was common, making ductless mini-splits the ideal retrofit solution. Whether you own a brick brownstone near Congress Street, a family home in Deering, or a condo overlooking Casco Bay, Southern Maine Heat Pumps has installed hundreds of systems throughout Portland and knows exactly what works in this vibrant coastal city.
Portland's coastal location brings cold winters, humid summers, and salt air that demands durable, reliable equipment. We install cold-climate heat pumps from Mitsubishi, Daikin, and Samsung that are engineered for Maine's weather and rated to operate efficiently down to -13°F. Our professional heat pump installations throughout Cumberland County follow manufacturer specifications and local building codes, ensuring your system delivers peak performance for years to come. And because we are based just minutes away in Gorham, you can count on responsive service whether you live in Munjoy Hill, Stroudwater, or anywhere in between. We also proudly serve neighboring communities including South Portland, Falmouth, Westbrook, and Cape Elizabeth.
Beyond installation, we offer comprehensive annual maintenance and service plans to keep your Portland heat pump running at peak efficiency. Our technicians clean coils, check refrigerant levels, inspect electrical connections, and verify performance so you can enjoy worry-free comfort season after season. We also install heat pump water heaters and design multi-zone systems for larger homes. Ready to lower your energy bills and increase your comfort? Contact us today for a free in-home consultation and learn how Efficiency Maine rebates can make upgrading more affordable than ever. Visit our contact page or call (207) 317-1077 to get started.
