Boiler Repair, Installation and Maintenance in Chicago
We service gas boilers, hot water boilers, tank-style systems and the older units found throughout Chicago homes. Whatever your boiler needs, one local team handles it from diagnosis to final pressure test. Looking for other heating help? See all HVAC services in Chicago.
Boiler Repair
Leaks, lost pressure, banging pipes, ignition failures and radiators that will not heat. Our boiler repair technicians diagnose the real cause, and most repairs are completed on the first visit with our fully stocked trucks.
Boiler Removal & Replacement
When an old boiler is inefficient, unsafe or failing, we drain, disconnect and remove it, then install a properly sized new system. Boiler installation includes venting, pressure testing, safety checks and thermostat calibration.
Boiler Maintenance & Cleaning
Annual boiler maintenance cleans internal components, checks pressure, inspects burners, tests safety controls and confirms even heat to every radiator, lowering bills and preventing breakdowns.
Pumps, Valves & Expansion Tanks
Hydronic systems depend on circulation pumps, pressure relief valves and expansion tanks working together. We repair and replace these components to restore steady pressure and heat.
Radiator & Hydronic Heating
Cast iron radiators, baseboard heat and zone valves need balanced flow and air-free lines. We bleed, balance and troubleshoot hydronic systems so every room heats evenly.
Commercial Boiler Service
Offices, small buildings, retail spaces and multi-unit properties rely on us for commercial boiler repair, installation and maintenance with minimal downtime through winter.
Boiler Heating in Chicago’s Older Homes and Buildings
Boiler heat is a big part of Chicago’s housing stock. Bungalows, greystones, two-flats and courtyard buildings from Lakeview and Lincoln Park to Hyde Park and Beverly still rely on hot water boilers and cast iron radiators, many of them decades old.
Why boiler heat is worth keeping
Radiant hot water heat is quiet, even and comfortable, with none of the dry, dusty air forced air systems can create. With good maintenance, a boiler system can serve a home for decades, and its radiators often outlast the boilers that feed them.
What we see most in older systems
Air trapped in the lines, radiators that are cold at the top, waterlogged expansion tanks, dripping pressure relief valves and worn circulation pumps. Most of these are fixable without replacing the boiler, and catching them early with annual maintenance prevents mid-winter failures.
Older pipe insulation
Some older Chicago boiler systems still have original pipe and boiler insulation that may contain asbestos. If it is damaged or needs to be removed during a replacement, it should be handled by a licensed abatement contractor before work begins.
Signs Your Boiler Needs Service
Boiler problems escalate fast in freezing weather. A small leak or a pressure drop can turn into a no-heat call overnight, so it pays to book boiler repair as soon as you notice any of these.

Chicago Boiler Service FAQs
Answers to the boiler questions Chicago homeowners and building owners ask us most.
Who provides boiler service in Chicago?
Tabor’s Complete Comfort Mechanical (TCC Mechanical) provides boiler repair, removal, replacement and maintenance across Chicago for gas and hot water boilers, radiator and baseboard systems, and light commercial buildings. The owner-led company has served Chicago since 2005. Call (773) 715-3860.
Do you remove old boilers in Chicago?
Yes. As part of a boiler replacement we drain the system, disconnect the old boiler and remove it, then install and test the new one. If old pipe insulation may contain asbestos, it should be handled by a licensed abatement contractor first.
How long does a boiler last?
Many residential boilers last 15 to 30 years, and well-maintained cast iron boilers can last even longer. Age alone is not a reason to replace one if it is still safe and efficient.
Why does my boiler keep losing pressure?
Common causes include small leaks in pipes or radiators, a failing pressure relief valve, a waterlogged expansion tank or a faulty fill valve. A technician can pinpoint the source and restore steady pressure.
Why are my radiators cold at the top?
That usually means air is trapped in the radiator. Bleeding the radiator releases the air, but if it keeps coming back there may be a leak, a pressure problem or an issue with the expansion tank.
Why is my boiler banging or making noise?
Banging and kettling are often caused by trapped air, mineral buildup in the heat exchanger, a failing pump or pressure problems. Left alone, they can lead to bigger failures.
How often should a boiler be serviced?
Once a year, ideally in late summer or early fall before the heating season. Annual service cleans internal components, checks pressure and safety controls, and helps prevent breakdowns.
Should I repair or replace my boiler?
Repair usually makes sense for isolated issues like a pump, valve or expansion tank. Replacement is worth considering when the boiler is old, inefficient, leaking from the heat exchanger or needs frequent repairs.
Do you service commercial boilers?
Yes. We provide commercial boiler repair, installation and maintenance for offices, small buildings, retail spaces, multi-unit properties and other light commercial buildings.
Which Chicago neighborhoods do you serve for boiler work?
We work across Chicago, including Lakeview, Lincoln Park, Hyde Park, Bronzeville, Wicker Park, Pilsen, the South Loop, South Shore, Beverly and Morgan Park, plus suburbs such as Oak Lawn, Orland Park and Tinley Park.
