Furnace Repair in New Brunswick
Steam boilers in century-old houses demand a different skill set than swapping parts in a modern furnace, and not every contractor has it. Guardian Air does — furnace repair in New Brunswick is part of a full heating practice that includes steam and hot-water boilers, heat pumps, and oil-to-gas conversions.
The county seat's housing leans old: multi-family Victorians, rowhouse blocks, and prewar singles where radiators still do the work. Our heating services keep those systems balanced and safe, with the same licensed technicians who handle the rest of our Middlesex County territory.
Landlords and homeowners both get priority repair response, flat-rate pricing, and honest guidance on repair versus replacement. Suburban neighbors are covered too — Old Bridge has its own dedicated page, as does Edison — all served by the same family-owned dispatch team that answers the phone here in the city.

Furnace Repair Problems We Fix in New Brunswick
Why New Brunswick Homeowners Choose Guardian Air
Old radiator systems reward patience and punish guesswork. Our technicians measure, test, and verify before recommending anything — which is how a hundred-year-old system keeps earning its keep instead of getting condemned prematurely.
City properties often mean tenants waiting in the cold, so we prioritize occupied no-heat calls, quote flat rates upfront, and document the work for owners who manage from a distance.

Furnace Repair in New Brunswick: FAQs
Do I need a permit to replace a furnace or boiler in New Brunswick?
Yes. Under New Jersey's Uniform Construction Code, swapping a furnace or low-pressure boiler for a new one of like capacity is "minor work": the contractor notifies the local construction office, files the permit application within five business days, and the job is inspected. Repairs such as replacing a control or igniter are ordinary maintenance and need no permit. In New Brunswick, permits and inspections go through the New Brunswick Construction Department on Kirkpatrick Street.
Who supplies natural gas and electricity in New Brunswick?
In City of New Brunswick, natural gas comes from PSE&G, and electricity from PSE&G. If you ever smell gas, leave the house first and call PSE&G's emergency line from outside — the utility handles leaks; we handle the heating equipment once it is safe.
What should I know about heating systems in older New Brunswick homes?
Half of the homes in New Brunswick were built in 1968 or earlier (U.S. Census ACS 2020–2024). Most of those houses are on their second or third furnace or boiler, but the flue, gas piping, ductwork, and radiator piping are often original — so a proper repair visit checks venting and distribution, not just the burner.
What license should an HVAC contractor in New Brunswick have?
A New Jersey Master HVACR Contractor license, issued by the State Board of Examiners of Heating, Ventilating, Air Conditioning and Refrigeration Contractors. A home improvement contractor registration is not an HVACR license, and you can look up any contractor's license on the NJ Division of Consumer Affairs website.
