Brockton · Heat Pumps
Planning a heat pump for a Brockton two-family, three-family, or single home? See how unit-by-unit planning, oil tank retirement, and city permits fit together, then get connected with a local installer.
Brockton, Massachusetts
In Brockton, a heat pump project is often a building project rather than a single-apartment one. Census estimates put more than a quarter of the city's housing units in two-, three-, and four-unit buildings, so the first question is usually how many apartments you're converting and whether each one gets its own outdoor unit, its own controls, and its own wiring back to its own meter.
Fuel is the second question. About 23 percent of occupied Brockton homes still heat with oil or kerosene, roughly 8,300 households, and another one in five relies on electric heat. Those homes have the clearest path to Mass Save's heat pump offers, because the program aims at replacing oil, propane, and electric resistance heat. Gas-heated homes can qualify too, through the gas account.
South Shore HVAC Finder doesn't install equipment. When you call or send a request, you're connected with an independent heating and cooling contractor who serves Brockton, and that business visits, designs the system, and writes the quote.
Separate electric service per unit makes it simpler to give each tenant or owner a system they control and pay for themselves.
If the tank or burner is due for replacement anyway, putting that money toward a heat pump instead of new oil equipment is worth pricing out.
Window units in every bedroom are a sign the building would welcome cooling that also heats, and that the wiring is already being pushed.
Uneven heat between floors of a stacked building is common with one shared boiler, and separate heat pump zones can even it out.
Local knowledge
Four local details shape how a Brockton heat pump job gets designed, permitted, and paid for.
Multi-Unit Buildings
About 11 percent of the city's housing units are in two-unit buildings and about 16 percent in buildings with three or four units. For an owner, that can mean separate systems per floor, separate electrical work per unit, and line sets routed past neighbors' windows, so ask for a layout drawing of every unit before you sign.
Oil Still Heats Many Homes
Oil and kerosene heat about 23 percent of occupied homes in the city. Leaving oil means a tank and burner to remove, and the Brockton Fire Department posts the oil burner and tank removal permit forms that cover that part of the work.
Lead Paint Risk
A 2026 regional housing assessment lists Brockton third among the 16 Massachusetts communities at highest risk for childhood lead exposure. Cutting chases, removing radiators, or opening walls for ducts can disturb old paint, which is why lead-safe work practices matter on this kind of job.

One Office For Inspections
Brockton's Building Department issues residential permits online and carries out the city's electrical and HVAC inspections, with wiring inspectors on staff at City Hall. A heat pump usually needs at least an electrical permit, so the wiring inspection is part of almost every job.

Right now
Owners of multi-unit buildings can save a lot of back-and-forth by sorting out a few things first.
Write down the National Grid electric account and any Eversource Gas account for each unit. Mass Save applications run through a residential account, so the installer needs to know which account goes with which apartment.
A home energy assessment shows where an old building leaks heat. Air sealing a drafty top floor before sizing can shrink the equipment that floor needs.
If the house predates 1978, ask every bidder how they handle painted surfaces they disturb, and keep the answer in writing with the quote.
Work out access dates, where indoor units will hang in each apartment, and how long any room will be out of use, before the schedule is set.
What to expect
Expect the contractor to walk every apartment, the basement, and the yard. In a stacked building, the hard part is often routing line sets and condensate lines from upper floors to outdoor units without crossing porches or blocking windows, and finding wall or ground space for several units on a narrow city lot.
Mass.gov says paid renovation work in housing built before 1978 must be done by a lead-safe renovation contractor when it disturbs more than 6 square feet of painted surface per room inside, or more than 20 square feet outside. A few small line set holes may stay under that line, but removing radiators or opening ceilings for ducts can cross it, so ask the question early.
The Building Department handles the permits and inspections for the heating, cooling, and electrical work. If the oil system is coming out, the Fire Department's tank removal permit covers that step, so make sure the quote names who files each one.
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.
Ask how many two- and three-family buildings the company has converted, and how it handled separate controls and electrical work for each unit.
For pre-1978 buildings, ask whether the company or its subcontractor holds a Massachusetts lead-safe renovation license, and look it up with the Department of Labor Standards.
Mass Save rebates require a contractor in its Heat Pump Installer Network. Ask each bidder to show they participate and to say which rebate type each unit is expected to get.
A building-wide lump sum makes it hard to compare bids. Ask for equipment, electrical work, and labor listed apartment by apartment.
Costs
The number of apartments is the biggest factor, followed by how many indoor heads each one needs and whether each unit's electrical service can take a new circuit. Long line set runs up the outside of a three-story building, wall brackets on upper floors, and lead-safe work practices in older rooms all add labor.
Removing an oil tank and burner is a separate cost to ask about, as is patching walls where radiators come out. Rebate rules change, so check current Mass Save terms yourself, then ask each installer for a written price with and without the rebate they expect, per unit.

Still not sure? Send a short request and a local pro can answer the specifics.
Often, yes. Each unit can have its own outdoor unit and controls tied to its own electric service. Ask the installer to show where every outdoor unit will sit and how the line sets will run before you commit.
They can. In pre-1978 housing, paid work that disturbs more than the state's painted-surface thresholds must be done by a lead-safe renovation contractor. Ask how much wall, ceiling, or trim the job will open up.
The city's Building Department issues the permits and performs electrical and HVAC inspections. If an oil tank is being removed, the Brockton Fire Department's tank removal permit applies to that part.
Mass Save offers include customers replacing natural gas heat where the gas utility is a sponsor, and Eversource is one. Those applications go through the gas account. Read the current program terms before you sign.
