How a Heat Pump Works
- Outdoor unit — fan and compressor extract heat from outside air
- Reversing valve — switches the system between heating and cooling
- Line set — carries hot, high-pressure refrigerant indoors
- Indoor coil — releases heat into the airstream
- Warm air — the blower delivers it to the room
Heat Pump Installation for Westbrook Homes
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.
What Happens on Installation Day?
Most single-zone installations are complete in one day. Our crew mounts the indoor head and outdoor unit, routes and insulates the refrigerant line set in clean line-hide, connects the system, pressure-tests and evacuates the lines, and commissions the system in both heating and cooling modes. We walk you through the remote and the maintenance schedule before we leave, and we take the packaging with us.

- About 49% of Westbrook homes heat with heating oil, so we size a heat pump installation job around the system already in the house and tell you plainly whether to keep it as backup for the coldest nights.
- Refrigerant work is done under EPA Section 608 certification, and the new circuit for the outdoor unit is permitted before it is wired.

Heat Pump Installation in Westbrook, ME FAQs
Do you offer heat pump installation in Westbrook, ME?
Yes. Westbrook is part of our Cumberland County service area, and J&R Mechanical Services handles heat pump installation for homes throughout the area. Call (207) 902-8899 or book online to schedule.
How long does a heat pump installation take?
A single-zone ductless installation is typically done in one day. Multi-zone systems usually take two to three days depending on the number of indoor heads.
What size heat pump does my home need?
It depends on your home’s heat loss, not just square footage. We perform a load calculation that accounts for insulation, windows, air sealing, and layout before recommending equipment. Oversized systems short-cycle and dehumidify poorly; undersized systems fall behind in deep cold. Sizing is the most important decision of the whole project.
