Boiler out on a Chicago winter night, a steam system hammering through your radiators, or pressure dropping with no warning? Our Chicago boiler repair technicians diagnose and fix all boiler types: steam, hot water, gas, and oil, getting to you fast across every neighborhood from the Loop to the far North Side.
We are Chicago's dedicated boiler repair contractor, serving two-flats, greystones, multi-family buildings, and commercial properties across the city. From a decades-old one-pipe steam system in a Pilsen two-flat to a high-efficiency condensing boiler in a new Lincoln Park development, our licensed technicians understand the full range of Chicago heating systems and the city codes that govern every repair job.
Whether your boiler stopped firing on a January night, is leaking water, making banging or clanking noises, or keeps dropping pressure, here is how our Chicago boiler repair technicians diagnose and fix every common heating problem.
When a Chicago boiler goes cold in February, every hour without heat matters, and Illinois law requires landlords to restore heating without unnecessary delay. Our emergency team is dispatched around the clock to diagnose ignition failures, gas valve faults, pilot outages, and control board issues that leave tenants without warmth.

Chicago's greystone and brick two-flat stock is full of one-pipe and two-pipe steam systems that have been heating homes for over a century. We repair pressuretrols, low-water cutoffs, steam vents, trap failures, banging pipes (water hammer), boiler feed pumps, and burner assemblies, bringing even the oldest cast-iron boilers back to reliable, even heat.

Circulator pump failures, waterlogged expansion tanks, zone valve faults, air locks, and pressure drops are the most common hot water boiler problems we encounter across Chicago. We also service mixing valves, aquastat controls, and condensate drain systems that freeze on high-efficiency condensing boilers during the city's brutal winters.

We repair all major oil boiler brands found in Chicago homes and commercial buildings, and our technicians stock the most common oil-system components on every service truck.

A broken boiler in a Chicago winter is not just uncomfortable; it is a legal liability for landlords and a genuine health risk for anyone in the building. Here is what Chicago property owners and building managers get when they call us.
Round-the-clock emergency boiler repair across Chicago: no-heat calls, steam leaks, and pressure failures from Lincoln Park to South Shore.
Call Us Now — 24/7No two boiler problems are the same. A faulty igniter or failed pilot is a straightforward one-visit repair, while a cracked heat exchanger or a full steam system overhaul is a more involved job. We always inspect your system first, walk you through exactly what we found, and give you a firm upfront quote before any work starts. Here is a full list of the boiler repairs we handle across Chicago.
For boilers under 10 years old with a single failing component, repair is almost always the smarter financial decision. Once a boiler is past 15 to 20 years, needing multiple fixes per heating season, or facing a heat exchanger replacement, a new unit often makes better long-term sense. Chicago winters are unforgiving, and an aging boiler that keeps breaking down is a risk you do not want heading into February. We give you an honest assessment either way, with no pressure to go in either direction.
We are a Chicago-based team, not a national chain dispatching from out of state. From the Loop and Lincoln Park to Bridgeport, Bronzeville, and Lakeview, our boiler technicians get to you fast for diagnostics, emergency no-heat calls, repairs, and annual tune-ups.
Common questions Chicago property owners and landlords ask about boiler repair costs, timelines, system types, and what to do when heat goes out mid-winter.
See why Chicago landlords and property managers call us first when a boiler fails in the middle of a polar vortex.
"Our Bronzeville two-flat lost heat on the coldest night of the year. I called after 10 PM and a technician was at the door within a couple of hours. He found a failed low-water cutoff, had the part on his truck, and had the boiler running again before midnight. Every tenant had heat. Genuinely impressive service."
"A contractor told us our Lakeview greystone needed a full boiler replacement for over $8,000. We called for a second opinion and they found a bad gas valve and a waterlogged expansion tank. Both fixed for a fraction of that price, and the boiler has been running without a problem since. Always get a second opinion."
