Common Boiler Problems We Repair
Not every boiler failure looks the same. Steam systems and hot water systems fail in different ways, and knowing the difference matters before a technician touches anything. Our EPA certified technicians diagnose the specific failure before recommending a repair — so you're paying to fix the actual problem, not to guess at it.
Steam boiler problems we repair:
- Failed or waterlogged steam traps causing cold radiators
- Stuck or malfunctioning low-water cutoffs
- Uneven heat from one radiator to the next
- Pressure relief valve failures
- Pilot or ignition failures
- Boiler short-cycling before reaching operating pressure
Hot water and hydronic boiler problems we repair:
- Circulator pump failure or loss of flow
- Air trapped in the lines causing cold zones
- System pressure loss or expansion tank failure
- Zone valve failures in multi-zone systems
- Heat exchanger scaling or corrosion
- Thermostat and aquastat control failures
When the heat goes out in a Chicago winter, every hour matters. Whether your radiators have gone cold, your boiler is cycling off before reaching temperature, or you're getting calls from tenants about uneven heat, we're ready to diagnose and repair the problem the same day you call. Online booking is available around the clock, and our team picks up the phone — 773-940-0965 is always the fastest route to a real person.

When Your Boiler Stops Heating, We Move Fast
An Honest Diagnosis Before Any Recommendation
One of the most common concerns we hear from homeowners and property managers is not knowing whether a repair is worth it or whether the boiler has simply reached the end of its life. Our technicians give you a straight answer. If the repair makes sense, we'll tell you what it costs and get it done. If the system is old enough and failing enough that replacement is the smarter call, we'll tell you that too — with the numbers to back it up.
We're an authorized Lennox dealer and an authorized Carrier dealer, which means when a replacement does make sense, we can put the right equipment in front of you. But the diagnosis always comes first, and it's always honest.

Boiler Repair Questions We Hear Most
What are the signs that my boiler needs repair rather than just a reset?
If your boiler is tripping the reset button repeatedly, producing uneven heat across rooms or floors, making banging or gurgling sounds, or showing pressure readings outside the normal range, those are signs of an underlying problem that won't resolve on its own. A reset may restore heat temporarily, but the fault that triggered the shutdown needs to be diagnosed and repaired.If your boiler is tripping the reset button repeatedly, producing uneven heat across rooms or floors, making banging or gurgling sounds, or showing pressure readings outside the normal range, those are signs of an underlying problem that won't resolve on its own. A reset may restore heat temporarily, but the fault that triggered the shutdown needs to be diagnosed and repaired.Can you repair both steam boilers and hot water boilers?
Yes. We service steam boilers, hot water boilers, and hydronic systems, including high-efficiency condensing boilers.

Maintenance agreement members receive priority scheduling ahead of the general queue.My radiators are heating unevenly — some rooms are hot and others are cold. Is that a boiler problem?
It can be. In steam systems, uneven heat is often caused by failed steam traps or venting issues at individual radiators. In hydronic systems, air in the lines, a failing circulator pump, or a stuck zone valve are common causes. We'll identify where the imbalance is coming from and fix it at the source.It can be.

The honest answer depends on the age of the system, the cost of the repair, and the efficiency of the current equipment. A boiler that's 15 to 20 years old and facing a major repair is often a stronger candidate for replacement. Our technicians will walk you through both options with real numbers — repair cost versus replacement cost and projected savings — so you can make the decision that makes sense for your home or building.The honest answer depends on the age of the system, the cost of the repair, and the efficiency of the current equipment.
