Getting to Know South Portland
During World War II, South Portland's shipyards launched more than 230 Liberty ships for the war effort, employing some 30,000 workers at their peak — many of them women welders. The city's beloved Bug Light and the Liberty Ship Memorial at Bug Light Park still mark where those hulls slid into Casco Bay.
Much of South Portland's housing went up for those shipyard families, and thousands of those postwar capes and bungalows still heat with oil today. Converting them to cold-climate heat pumps is some of the most satisfying work we do — cutting fuel bills dramatically while adding the summer cooling these homes never had.

Beyond installation, we offer a full range of services for South Portland homes and businesses.
