Boiler Repair in Jersey City
Licensed Boiler Repair Since 1921: Residential, Commercial, Industrial & Municipal
William J. Guarini Inc. has been repairing boilers in Jersey City since 1921. Over a century of hands-on heating work means our team has seen every failure mode a boiler system can produce, across every building type in Hudson County. We’re fully licensed and insured, and we work with residential, commercial, industrial, and municipal clients throughout Jersey City, Hudson County, Essex County, and Bergen County.
Jersey City’s older building stock runs heavily on boiler-based heating. When those systems fail, getting a licensed technician on-site quickly matters. Gas-fired boiler repair requires proper credentials under New Jersey regulations, and our team meets those requirements.

Signs Your Boiler Needs Professional Repair
Some boiler problems announce themselves clearly. Others develop gradually until the system stops working altogether. Either way, catching them early can help limit the damage.
Common signs a boiler requires attention:
- No heat or noticeably reduced heat output
- Banging, gurgling, or whistling sounds from the system
- Pressure relief valve discharging water
- Pilot light or ignition failure
- Leaks or water pooling around the unit
- Frequent short cycling (the unit turns on and off rapidly)
- Rising energy bills with no change in usage
Our team handles everything from minor component repairs to complete system overhauls. Repair costs vary depending on what’s failed: typical boiler repairs run $150 to $700, while more involved work such as circulating pump or coil replacement can reach $300 to $1,100. Emergency repair service is part of our boiler offering for qualifying customers.
Boiler Types We Service in Jersey City
Not every contractor works on every system. Our heating team is trained and equipped to service the full range of boiler types found across Jersey City and the surrounding area.
- Hot water boilers (hydronic heating systems common in residential and commercial buildings)
- Steam boilers (found throughout older Jersey City brownstones and multi-family buildings, requiring advanced repair knowledge)
- High-efficiency condensing boilers (increasingly common in renovated and newer residential properties across New Jersey)
- High-efficiency combination tankless boilers (units that handle both space heating and domestic hot water)
We also support larger commercial, industrial, and municipal boiler systems. The same team that services a residential steam boiler can also handle the heating infrastructure of a large facility.
