HVAC in Brunswick, ME
J&R Mechanical Services is a full-service heating and cooling company covering Brunswick, ME — one of our two primary service areas, along with Augusta. We install, repair, and maintain heat pumps, furnaces, boilers, and air conditioning for Brunswick-area homes, with plumbing capability on the same crew for gas piping and condensate work.
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 Pumps & Mini-Splits
Cold-climate heat pumps and ductless mini-splits suit Brunswick’s mix of older and newer housing well, delivering efficient heating and cooling from a single system. We size and install heat pump systems for whole-home or single-room use, and service existing units from most major brands.
Boilers & Hydronic Heating
Many Brunswick-area homes run on oil, propane, or gas-fired boilers with baseboard or radiator heat. We provide annual cleanings, boiler repairs, and full boiler replacements, and can pair a boiler with a heat pump as a backup-and-primary combination.
Furnace Repair & Installation
For forced-air Brunswick homes, we diagnose and repair furnaces of all major brands and install high-efficiency replacements when a repair no longer makes sense.
Air Conditioning
Central and ductless air conditioning installation and repair, including heat pump systems that handle both heating and cooling from one piece of equipment.
Codes & Permits for HVAC in Brunswick
In Brunswick, plumbing permits come from the Local Plumbing Inspector at the Planning & Codes Office, Town of Brunswick Dept. of Planning and Development (85 Union Street, Brunswick, ME 04011, 207-725-6660). With 21,756 residents, Brunswick is required to enforce the Maine Uniform Building and Energy Code (MUBEC). Brunswick's housing stock is comparatively newer than Portland's or South Portland's — median year built 1982, with only ~19.5% of homes built in 1939 or earlier (ACS 2020–2024 via Census Reporter).
- Anyone who connects or disconnects gauges or adds/removes refrigerant on a heat pump or air conditioner must hold EPA Section 608 technician certification; the credential does not expire once earned. epa.gov
- The electrical circuit that feeds a new heat pump or AC condenser needs an electrical permit, issued by the Electricians' Examining Board or the town's own electrical inspector, before the wiring is installed or altered. maine.gov
- Efficiency Maine offers rebates of up to $9,000 on qualifying heat pumps, but the equipment must be installed by an Efficiency Maine Residential Registered Vendor for the homeowner to receive the rebate. efficiencymaine.com
How J&R Handles HVAC in Brunswick
- About 45% of Brunswick homes heat with heating oil, so we size a HVAC 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.

HVAC in Brunswick, ME FAQs
Do you service every brand of HVAC equipment in Brunswick?
We work on most major residential heat pump, furnace, and boiler brands. If a part is not readily available, we tell you before you pay for a second visit.
Should I repair or replace my Brunswick home’s heating system?
If the system is relatively new and the repair cost is a small fraction of replacement, repair usually wins. With an older system or repeat failures, replacement — often with a heat pump that also cools — can pay back faster. We give you both prices and let you decide.
