Why Commercial Boiler Repair Requires Specialists

Commercial boilers are high-pressure, high-temperature systems that demand specialized knowledge and training. They operate under conditions far more demanding than residential equipment — running extended hours, often 24/7, while providing heat and hot water to large commercial and industrial facilities. Proper repair requires technicians who understand these unique commercial demands and the safety considerations involved.

Common commercial boiler failures include no heat conditions, water leaks, pressure fluctuations, ignition or pilot failures, circulator pump problems, expansion tank issues, and control system malfunctions. Our technicians use professional diagnostic equipment to identify the root cause quickly, not just the symptoms, ensuring repairs last and prevent recurring issues.

We stock common commercial boiler parts on our service vehicles and have priority access to replacement components through our established supplier relationships. When parts aren't immediately available, we provide temporary solutions when possible to keep your building heated while we source what's needed.

Common Boiler Problems We Fix

No heat is the most urgent commercial boiler problem, especially during cold weather. Our technicians diagnose and resolve ignition and heating failures quickly to restore warmth to your building.

  • Ignition failure — faulty igniters, flame sensors, or gas valve problems
  • Pilot light issues — intermittent or complete pilot failure on standing pilot systems
  • Thermostat malfunctions — incorrect readings or communication failures preventing heat calls
  • Control board lockouts — safety shutdowns requiring professional reset and diagnosis
  • Gas supply problems — gas valve failures or supply pressure issues

  • Water leaks — from valves, fittings, heat exchangers, or corroded piping
  • Low water pressure — causing shutdowns via low-water cutoff safety controls
  • High pressure conditions — relief valve discharge or dangerous over-pressurization
  • Expansion tank failures — waterlogged or failed tanks causing pressure swings
  • Pressure relief valve problems — leaking, weeping, or failing to reset properly

  • Circulator pump failure — pumps not moving water through the heating loop
  • Zone valve malfunctions — zones not receiving heat or stuck open/closed
  • Heat exchanger problems — cracked, corroded, or scaled-up heat exchangers
  • Air lock in system — trapped air preventing proper water circulation
  • Kettling and noise — limescale buildup causing banging, rumbling, or whistling sounds

Our Boiler Diagnostic Process

  • Gather information about symptoms, timing, and recent changes
  • Visual inspection of the boiler, piping, and connections for leaks or damage
  • Check error codes on the control board and review fault history
  • Verify water pressure and temperature readings on gauges
  • Check thermostat settings and zone control communication

  • Combustion analysis testing flue gas temperatures, CO levels, and efficiency
  • Pressure and temperature testing across the system at multiple points
  • Electrical testing of ignition system, controls, pumps, and safety devices
  • Safety control verification testing low-water cutoffs, relief valves, and limit controls
  • Circulator and flow testing verifying proper water circulation through all zones

Boiler Repair vs Replace Decision Guide

Repair is typically the best option for newer equipment or when the repair cost is reasonable relative to the boiler's remaining useful life. Commercial boilers often have longer lifespans than other HVAC equipment, making repair frequently the smart choice.

  • Boiler is less than 15-20 years old with significant life remaining
  • Repair cost is under 50% of replacement cost
  • First major failure with no pattern of recurring problems
  • Heat exchanger is intact with no cracks or significant corrosion
  • Boiler still operates efficiently with reasonable fuel consumption

  • Boiler is over 25-30 years old approaching end of useful life
  • Cracked heat exchanger which is unsafe and costly to replace
  • Frequent repairs with increasing frequency and cost
  • Severe corrosion on sections, headers, or internal components
  • High fuel bills that a new high-efficiency boiler would significantly reduce

  • We never push unnecessary replacements — if repair makes sense, we'll tell you
  • Transparent cost comparison of repair vs replacement options
  • Energy savings analysis showing potential savings with a new high-efficiency boiler
  • Financing options available if replacement is the best path forward
  • Written repair estimates before any work begins

Frequently Asked Questions

Get answers to your commercial boiler repair questions

We provide priority emergency service for commercial boiler failures and respond as quickly as possible. A no-heat situation in a commercial building is always treated as urgent, especially during cold weather when frozen pipes and building damage are risks. Call (708) 231-4800 for immediate emergency boiler repair service.

Yes, we provide emergency service for commercial boiler failures outside normal business hours. We understand that a boiler failure can't wait — your building needs heat, your pipes need protection, and your business or tenants need comfort. Call us any time for emergency commercial boiler repair service.

Commercial boiler repair costs vary widely depending on the problem, parts needed, and boiler type. Minor repairs like replacing an igniter or flame sensor are relatively affordable, while major repairs like heat exchanger or circulator pump replacement are more significant investments. We provide a written estimate before starting any repair work so you can make an informed decision.

The most common commercial boiler failures include ignition problems, circulator pump failures, water leaks, pressure fluctuations, expansion tank issues, zone valve malfunctions, low-water cutoff shutdowns, and control board failures. Many of these can be prevented with regular professional maintenance.

First, check the thermostat settings and verify power to the boiler. Check if the system pressure gauge reads within normal range. If the boiler has a reset button, you can try resetting it once — but if it locks out again, do not keep resetting it as this could indicate a serious problem. Call (708) 231-4800 for emergency service and we'll dispatch a technician as quickly as possible.

Repeated pressure loss in a commercial boiler system usually indicates a water leak somewhere in the system — at the boiler itself, in the piping, at fittings or valves, or through the pressure relief valve. A failed expansion tank can also cause pressure problems. Our technicians will inspect the entire system to locate the source of pressure loss and provide a permanent repair.

In many cases, yes. The repairability depends on where the leak is located. Leaks at fittings, valves, and piping connections are typically straightforward repairs. Leaks from the heat exchanger itself may indicate more serious corrosion damage that could require section replacement or, in severe cases, boiler replacement. We'll diagnose the source and provide honest guidance on the best course of action.

Yes, we service multi-boiler configurations, lead-lag systems, and industrial boiler applications. Multi-boiler systems require technicians who understand sequencing controls, common header piping, and how individual boiler failures affect overall system performance. Our experienced commercial technicians handle these complex systems regularly.

Regular professional preventive maintenance is the single most effective way to prevent boiler breakdowns. Maintenance includes combustion analysis, safety control testing, water quality checks, and inspection of all components. We recommend annual maintenance at minimum, with pre-season tune-ups before winter to catch problems before they leave you without heat.

Yes. After diagnosing the problem, we provide a clear, written estimate detailing the necessary repairs and costs before beginning any work. You'll know exactly what's needed and what it will cost. If we discover additional issues during repair, we'll communicate those before proceeding with any extra work.
