Heat Pump Installation in South Portland, Maine

When South Portland homeowners need heat pump installation, Aces Highlands is the local team to call. We are based at 508 Riverside St Unit 1 in Portland — a short drive from South Portland in Cumberland County — so we respond quickly and know the homes, the weather, and the codes in your area.

We are certified installers for GE and Hitachi cold-climate heat pumps rated to perform in sub-zero temperatures, and we also work with other major brands to find the right fit for your home and budget. Every installation starts with a proper load calculation to ensure your system is sized correctly — not too big, not too small. Most heat pump installations also require an electrical panel upgrade — we handle that as part of the project.

Our installations include indoor and outdoor unit placement, refrigerant line routing, electrical connections, and thorough system testing. We take pride in clean line sets, secure mounting, and a tidy work area when we leave.

Whether you are adding a single-zone mini-split to a problem room or installing a multi-zone ductless mini-split system for whole-home comfort, we communicate clearly about what to expect and deliver on time. We offer financing options to make your installation more affordable.
