Boiler Repair

Our technicians handle boiler repair on all boiler types and brands. Common problems we fix:

• No heat or not enough heat
• Pilot light, igniter or burner problems
• Banging, clunking or whistling pipes
• Leaks, low pressure or a leaking relief valve
• Circulator pump and zone valve failures
• Steam boiler water level, low-water cutoff and venting problems
• Thermostat and control issues

Boiler Replacement and Installation

It may be time to replace your boiler if:

• It’s more than 15 to 20 years old
• Repairs are becoming frequent
• Energy bills keep rising despite maintenance
• You see leaks or visible corrosion
• Some rooms never get warm enough

We size every new boiler to your home or building using a heat loss calculation, not just the old unit’s rating. Options include high-efficiency condensing boilers, combination boilers that also provide hot water, and steam boiler replacements.

Annual Boiler Maintenance

An annual tune-up keeps your boiler safe and efficient and catches problems before the first cold snap. Our boiler service includes burner cleaning and adjustment, combustion analysis, safety control and relief valve testing, checks for leaks and corrosion, pump and expansion tank checks, and, for steam systems, low-water cutoff testing and gauge glass inspection. Schedule it in early fall, before heating season. See our maintenance plans.

Boiler Brands We Service

We work on all major brands, including Weil-McLain, Burnham, Navien, Lochinvar, Buderus, Viessmann, Peerless and Triangle Tube.

Rebates and Financing

As a PSE&G Trade Ally, we apply PSE&G instant rebates to high-efficiency boilers, and eligible PSE&G customers can spread the cost over time with 0% on-bill repayment. We also offer financing through NEIF and JB Financing.
