Ductless Mini-Splits
Ductless mini-split heat pumps are the ideal solution for homes without existing ductwork, room additions, renovations, and spaces that need targeted temperature control. Southern Maine Heat Pumps specializes in installing whisper-quiet mini-split systems that provide both heating and cooling from a single, compact unit. With individual room control and non-invasive installation, mini-splits deliver exceptional comfort without the cost and disruption of adding ductwork to your home.
Many homes in the Gorham, Portland, Westbrook, and Scarborough areas were built long before central ductwork was standard. If your home relies on oil-fired boilers, electric baseboard heaters, or window air conditioning units, a ductless mini-split system is the most efficient and cost-effective path to modern comfort. At Southern Maine Heat Pumps, we have installed hundreds of ductless systems in older Cape Cod homes, colonials, and ranch-style houses throughout Cumberland County, giving homeowners year-round heating and cooling without tearing open walls to run ductwork.
Ductless mini-splits are also the go-to solution for room additions, finished basements, above-garage studios, and sunrooms that your existing HVAC system cannot adequately reach. A single indoor unit mounted on a wall or ceiling connects to a compact outdoor compressor through a small conduit, meaning installation typically takes just one day with minimal disruption. From Cape Elizabeth to inland communities, the result is whisper-quiet, zone-controlled comfort that lets you heat or cool only the rooms you are using, saving energy and money every month.
If you need to condition multiple rooms, consider upgrading to a multi-zone heat pump system that connects several indoor units to a single outdoor compressor. For whole-home comfort in homes with existing ductwork, our standard heat pump installation service may be the perfect fit. We also recommend pairing your mini-split with an annual maintenance plan to keep filters clean, refrigerant charged, and efficiency at its peak throughout every Maine season.
Perfect for Older Maine Homes
Many homes across Cumberland County were built in an era before central air conditioning and modern HVAC systems. These beautiful older homes—whether Cape Cods, colonials, or historic farmhouses—often lack the ductwork needed for traditional heating and cooling systems.
Ductless mini-split systems are the ideal solution for these homes. Without requiring invasive renovations or expensive ductwork installation, mini-splits deliver efficient, year-round comfort to Cumberland County homeowners who want modern climate control while preserving their home's character and avoiding major construction projects.
