Chicago has more boiler-heated homes than most cities, from vintage two-flats and greystones to bungalows and older suburban homes. Our technicians work on these systems every day, whether you have a century-old steam system or a new high-efficiency combi boiler. You'll get an upfront, by-the-job price before any work begins.

Steam and Hot Water Boiler Repair

Steam boilers are common in older Chicago buildings. We repair low-water cutoffs, pressure controls (pressuretrols), sight glasses, main vents, radiator valves, and the water-hammer and uneven-heat problems steam systems are known for.

Hot water (hydronic) boilers heat through radiators, baseboard or radiant floors. We repair circulator pumps, expansion tanks, zone valves, pressure relief valves, air in the lines and leaks.

High-efficiency and combi boilers need specialized diagnosis. We repair condensing boilers, combi units that also supply hot water, and their electronic controls and venting.

Signs You Need Boiler Repair

Radiators are cold or only partly warm. Often air in the system, a failed circulator or a steam venting problem.
Banging, knocking or gurgling pipes. Water hammer in steam systems or air in hot water systems.
Leaks or puddles around the boiler, pipes or radiators.
Pressure is too high or too low on the gauge.
The pilot or burner won't stay lit.
The boiler short-cycles or runs constantly.
Rising gas bills with no change in use.

If you smell gas, leave the home and call your gas utility. If your CO alarm sounds, leave and call 911.

24/7 Emergency Boiler Repair

Boilers don't wait for business hours to fail, and neither do we. ABC answers 24/7 with a real person and dispatches technicians nights, weekends and holidays across Chicagoland.

Repair or Replace Your Boiler?

Well-maintained boilers often last 20 to 30 years or more, so repair is usually the first option. Replacement is worth discussing when:

The boiler is near the end of its life and needs a major repair
The heat exchanger is cracked or leaking
Repairs are becoming frequent
You want lower bills from a high-efficiency boiler

We'll give you an honest recommendation and show you boiler installation options and financing if replacement makes more sense.

Boiler Repair FAQs

Why are some of my radiators cold? In hot water systems, trapped air is the most common cause, and bleeding the radiators often helps. In steam systems, a stuck or failed radiator vent is a frequent culprit. If the problem continues, call for service.

Why is my boiler pressure gauge high? High pressure can point to a failing expansion tank, fill valve or relief valve. It's a safety issue, so call for service.

Do you work on steam heat in older Chicago buildings? Yes. Steam systems in two-flats, greystones and older homes are a large part of our boiler work.

How much does boiler repair cost? It depends on the part and system. You'll get a flat, upfront price after diagnosis and before any work starts.
