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

Built for Cumberland County Winters

Cold-climate heat pump units are rated to heat efficiently well below freezing, with reduced output as temperatures drop further. Most Brunswick homeowners we install for keep their existing furnace or boiler in place as backup for the coldest nights, rather than removing it.

Sized From a Real Load Calculation

A single-zone ductless mini-split is generally the simplest install; multi-zone and ducted whole-home systems take more planning depending on the number of zones and line-set length. You get a firm written price before any work starts.

After the Install

Every heat pump installation includes a walkthrough of the controls and a maintenance schedule — annual professional service plus monthly filter washing during heavy use keeps the system running at peak efficiency.

How J&R Handles Heat Pump Installation in Brunswick

About 45% of Brunswick 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.
Efficiency Maine rebates only apply when a Residential Registered Vendor installs the equipment, so we go over rebate eligibility with you before you commit, and you can check any installer’s registration.
