HVAC & Plumbing Services in Portland, Maine

Knowles Mechanical is proud to serve Portland, Maine's largest and most vibrant city. From the historic buildings of the Old Port to residential neighborhoods throughout the peninsula and beyond, we provide comprehensive HVAC, plumbing, and electrical services to keep Portland properties comfortable and efficient. Our team understands the unique requirements of this coastal city, where maritime weather influences heating and cooling needs year-round.

Portland's diverse architecture presents varied HVAC challenges. Victorian homes in the West End require different solutions than modern condominiums on the waterfront. Our experienced technicians are skilled in servicing all types of heating and cooling systems, from traditional forced-air furnaces to cutting-edge heat pump technology. We specialize in ductless mini-split systems that are ideal for Portland's many older buildings where installing ductwork would be impractical or impossible.

The Greater Portland area experiences milder winters than inland Maine due to the ocean's moderating influence, but reliable heating remains essential. Our services include furnace installation and repair, boiler service, heat pump installation, and emergency heating repairs. For cooling, we offer central air conditioning systems, ductless mini-splits, and routine maintenance to keep your system running efficiently throughout the summer months.

Portland businesses rely on Knowles Mechanical for commercial HVAC solutions. We serve restaurants along Congress Street, retail shops in the Old Port, office buildings downtown, and commercial properties throughout the metro area. Our commercial team handles everything from routine maintenance to complete system installations, always working to minimize disruption to your business operations.
