Pembroke · Heat Pumps
Planning a heat pump for your Pembroke home? Find out which electric company and permits apply, what to ask about sizing, and how to reach an independent local installer.
Pembroke, Massachusetts
Start with your electric bill. Pembroke is one of the South Shore towns split between two electric companies: state listings show both Eversource and National Grid serving the town, and there is no municipal light plant. Both companies sponsor Mass Save, but the account on your bill decides whose program paperwork you'll use, so have it handy when you talk to an installer.
The housing helps. About 84 percent of occupied homes here are single-family detached houses and about 90 percent are owner-occupied, so most homeowners can decide where an outdoor unit goes without a condo board or landlord. That puts the choice of a quiet spot, away from bedroom windows and the driveway plow pile, in your own hands.
We're a referral service rather than an installer. One call or online request connects you with an independent HVAC contractor who works in Pembroke and can quote the system for your house.
A burner or tank near the end of its life is a natural moment to price a heat pump against a like-for-like replacement.
One system can heat in January and cool in July, which matters in homes that never had central air.
Resistance baseboard turns electricity straight into heat, while a heat pump moves heat and usually uses far less power for the same comfort.
New windows, insulation, or air sealing since the original system went in can make a smaller heat pump a practical choice.
Local knowledge
Utility service, housing type, and permit rules all play into a Pembroke heat pump job.
Check Your Utility
Eversource and National Grid both appear in the state's electric company listing for Pembroke. Gas in town comes from Eversource, so a home on Eversource gas and National Grid electric may deal with two Mass Save sponsors on one project.

Detached Homes
Old Colony Planning Council's June 2026 slides put single-family detached homes at 83.8 percent of occupied units, using 2024 figures. Detached houses usually have more choices for unit placement and line set routes than attached housing.

Electrical Permit
Heat pumps need a dedicated electrical circuit, and Pembroke's electrical permits are filed through the Simplicity portal and inspected by the town's wiring inspector. Ask the installer whether an electrician is part of their crew or a separate hire.

Right now
A little preparation makes estimates easier to compare.
Write down whether the account is Eversource or National Grid, plus your gas account if you have one. Installers need this to explain which offers might apply.
Mass Save offers a home energy assessment that can flag insulation and air sealing work. Doing that first can shrink the heat pump you need.
Snap a photo of the panel label and the breakers, without removing any covers. It helps a contractor judge whether an upgrade might be needed.
Think about places clear of roof drip lines, drifting snow, and low ground that holds water, then ask the installer to weigh in.
What to expect
A good quote starts with a room-by-room heat loss calculation rather than a guess from square footage. The contractor should also ask how you want to use the system: as the only heat, or alongside an existing boiler or furnace for the coldest nights.
Pembroke permits for the work go through Building and Inspectional Services on the Simplicity system. A ducted system can need a sheet metal permit as well as the electrical permit, and every application carries a Workers' Compensation Affidavit. Inspections are scheduled by the Building Department for the next day or the first open slot.
Installation itself typically means setting the outdoor unit on a pad or stand, running refrigerant lines and a condensate drain, wiring the circuit, and commissioning the system. Ask the installer to show you the controls and cleaning schedule before they leave.
Hire smart
Massachusetts has no single HVAC license. Gas work needs a gas fitter license, oil burner work a Department of Fire Services certificate, ductwork a sheet metal license, and larger refrigeration systems a refrigeration technician license. Most heating and cooling installs need a town permit.
Ductwork calls for a sheet metal license and the wiring for an electrician's license. Search the state's occupational license lookup for the names on your estimate.
Ask the installer how they handle Mass Save paperwork for Eversource versus National Grid customers and who submits the rebate forms.
Ask for the model numbers and how each unit performs at low outdoor temperatures, so you can compare quotes on the same terms.
The estimate should list indoor and outdoor units, electrical work, permits, line set covers, and whether the old system is removed or kept as backup.
Costs
The size and layout of the house, how well it's insulated, and the number of indoor units set most of the price. Ductwork that's already in good shape can make a ducted heat pump simpler, while a house heated by a boiler may need several ductless heads instead.
Electrical work is the wild card. An older panel may need an upgrade before a heat pump can be added. Ask for written estimates from more than one Pembroke installer, with any expected Mass Save offers listed separately so you can see the cost before and after.

A heat pump proposal is only as good as the design behind it. These questions help you compare quotes, protect your rebate eligibility, and avoid a system that's the wrong size for your house.

No. Pembroke's electricity comes from Eversource or National Grid, depending on the address, and both participate in Mass Save. Confirm current offers with Mass Save or your installer before you sign.
Many cold-climate heat pumps are designed for that, but it depends on the house. A heat loss calculation will show whether one system can carry the coldest nights or whether keeping the existing boiler or furnace as backup makes sense.
Usually an electrical permit, and a sheet metal permit if ducts are involved, both filed through the town's Simplicity portal. The contractor normally files them and books the inspection.
Keep it above ground that floods or holds snowmelt. Pembroke has large areas of mapped floodplain near its rivers and ponds, so ask the installer about a raised stand or wall bracket if your yard sits low.
