Randolph · Furnaces
In Randolph, a furnace swap means a gas or oil permit, an inspection, and a house that's likely from the 1950s or 1960s. Here's what to expect before you call an independent local contractor.
Randolph, Massachusetts
In Randolph, replacing a furnace usually starts online. The town takes building, gas, electrical, and plumbing permit requests through its PermitEyes system, and the gas fitter on the job is the one who typically files. Knowing that up front helps you ask the right questions when quotes come in.
The houses themselves set the stage. Census estimates put Randolph's median year built at 1966, and roughly 36 percent of its homes went up between 1950 and 1969. About 55 percent of occupied homes heat with Eversource gas and about 21 percent with oil, so most furnace calls involve one of those two fuels.
This page covers the signs, the safe first steps, and what the town's process looks like. Our role ends at the introduction: a call or request connects you with an independent furnace contractor serving Randolph, who works out the price directly with you.
A gas flame that's mostly yellow, flickers wildly, or lifts off the burner can indicate a combustion problem. Shut the furnace off and have it checked.
A fan that runs constantly even when the burner is off may have a thermostat set to on, a stuck relay, or a limit switch that's tripped.
Dark streaks where the flue pipe meets the chimney suggest the furnace isn't venting properly, which is a carbon monoxide concern.
A sharp rise in gas or oil use without a cold spell to explain it often means the furnace is losing efficiency or running longer cycles than it should.
Local knowledge
Permits, housing age, and fuel type all point to what a Randolph furnace job involves.
PermitEyes Filing
Randolph's Building Department takes gas, plumbing, electrical, and building permit requests online through PermitEyes. A furnace replacement that touches the gas line needs a gas permit filed there.

Inspector Schedule
The Building Department lists its plumbing inspector on Mondays, Wednesdays, and Thursdays, with inspection requests taken before 9 a.m. A replacement may need to be timed so the inspection fits that schedule.
Mid-Century Homes
Census estimates put the median at 1966, with about 2,500 units from the 1960s and about 2,200 from the 1950s. Original flues and duct layouts from that era deserve a look whenever the furnace is replaced.
Right now
Here is a sensible order of operations.
A gas smell or CO alarm is the one situation where you don't troubleshoot. Leave with everyone, including pets, then call 911 or Eversource from outdoors and keep your distance until it's declared safe.
A furnace needs power for its blower and controls. Make sure the service switch is on and the breaker hasn't tripped; if it trips again, stop and call.
Note any noises, error light blinks on the control board, and when the trouble started. This helps the technician narrow the cause quickly.
What to expect
A repair visit generally covers the ignition sequence, gas pressure or oil burner settings, the blower, safety controls, and venting. A carbon monoxide check around the furnace and flue should be included, and you can ask for readings in writing.
For a replacement, the contractor files the gas permit through PermitEyes and books the inspection. If the furnace burns oil, ask whether the Randolph Fire Department needs an oil burner or tank permit for your job and who is filing it.
Split-levels and raised ranches from the 1960s often have the furnace on a lower level near laundry or a garage. Clear a path and point out any finished walls that hide ducts or the flue connection.
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.
Gas furnace work requires a Massachusetts gas fitter license. Search the contractor or technician on the state's occupational license site and make sure the license is current.
For an oil furnace, check the technician's oil burner certificate on the Department of Fire Services verification page.
Get confirmation that the contractor files the gas permit and schedules the inspection, and ask for the permit number.
Ask two or three contractors to list the same items: equipment, permits, venting, duct work, and removal of the old furnace.
Costs
Repair costs track the failed component and how easy it is to reach. A sensor, igniter, or filter-related shutdown is a smaller job than a draft inducer, gas valve, or heat exchanger. Older furnaces may also need parts that take longer to source.
For a new furnace, venting is a common variable in 1950s and 1960s houses: a high-efficiency unit vents through plastic pipe, while a mid-efficiency unit may need a chimney liner. Ask for each option in writing, with permits and removal included, and ask whether Mass Save offers apply.

Yes. Gas work in Randolph needs a gas permit, which is requested online through the town's PermitEyes system, usually by the gas fitter doing the job.
The Building Department lists its plumbing inspector on Mondays, Wednesdays, and Thursdays, with requests taken before 9 a.m. Your contractor can tell you how the inspection fits into the project.
It depends on the furnace. A high-efficiency model usually vents through plastic pipe instead of the chimney, while a mid-efficiency model may need the chimney lined. Ask the contractor to explain the venting plan.
A buyer's inspector will likely test it, and the sale also needs a smoke and CO certificate from the Randolph Fire Department, which is valid for 60 days. Getting the furnace checked before listing avoids surprises.
