Boiler Repair & Installation — Chicago
How much does boiler repair cost in Chicago?+
Boiler repairs in Chicago typically range from $200 depending on the issue. Common repairs include circulator pump replacement ($350), pressure relief valve replacement ($180), and heat exchanger repair ($600). D's Air charges a Technical Visit — $95.35 that covers travel, fuel, diagnostics, and technician evaluation. This fee is separate from repair costs.
How much does a new boiler cost installed in Chicago?+
A new residential boiler installation in Chicago ranges from $3,500 to $8,500 depending on the brand, BTU output, and system type (hot water vs. steam). High-efficiency condensing boilers (Weil-McLain, Navien, Viessmann) run higher but deliver significant long-term energy savings.
What is the difference between a hot water boiler and a steam boiler?+
A hot water (hydronic) boiler heats water and circulates it through radiators or radiant floor tubing. A steam boiler heats water until it becomes steam, which rises through pipes to radiators. Steam systems are common in older Chicago two-flats and greystones. Both require specialized service — D's Air services both types.
How long does a boiler last?+
A well-maintained boiler typically lasts 20–30 years. Cast iron boilers (Weil-McLain, Peerless, Crown) are known for exceptional longevity. Annual maintenance — including flushing, pressure checks, and burner inspection — is the single best way to extend boiler life.
Why is my boiler making a banging or knocking noise?+
Banging or knocking from a boiler is often caused by kettling (mineral scale buildup on the heat exchanger), trapped air in the system, or a failing circulator pump. Steam boilers may bang due to water hammer — steam and condensate colliding in the pipes. These issues should be diagnosed promptly to prevent damage.
Do you service combi boilers?+
Yes. D's Air services combination (combi) boilers from Navien, Noritz, Viessmann, Rinnai, and Bosch/Buderus. Combi boilers provide both space heating and domestic hot water from a single unit and are increasingly popular in Chicago condos and smaller homes.
What brands of boilers do you service?+
D's Air services all major boiler brands including Weil-McLain, Bosch, Buderus, Navien, Noritz, Viessmann, Rinnai, Crown, Peerless, Burnham, Dunkirk, Slant/Fin, and more. We carry common parts on the truck for most brands.
My boiler pressure keeps dropping — what does that mean?+
A boiler that repeatedly loses pressure usually has a water leak somewhere in the system, a failing expansion tank, or a faulty pressure relief valve. Low pressure prevents the boiler from heating properly and can cause the system to shut down on a safety lockout. Call D's Air at (773) 940-0965 for a same-day diagnostic.

What Chicago Homeowners Should Know About Boiler Repair
Most Common Boiler Problems
Frequent boiler failures in Chicago include: low water pressure or water level (hot water and steam systems respectively), failed circulator pump (no heat distribution), faulty pressure relief valve, pilot light or ignition failure, zone valve failure, and kettling (rumbling noise caused by limescale buildup on the heat exchanger).
Steam Boiler Specific Issues
Steam systems require proper water level maintenance. Too little water triggers the low-water cutoff and shuts the boiler down. Too much water causes water hammer — the banging and clanking you hear in the pipes. Proper water treatment and annual maintenance prevent most steam boiler problems.
When to Repair vs. Replace
Boilers last 25–35 years with proper maintenance. If your boiler is under 20 years old and the repair is under $1,500, repair usually makes sense. If it's over 20 years old, requires a major component (heat exchanger, gas valve, control board), or has visible corrosion, replacement is often the better investment.
Emergency Boiler Service
A boiler failure in a Chicago winter is an emergency. D's Air provides priority service for no-heat calls. If you smell gas near your boiler, leave the building immediately, do not operate any switches, and call the gas company and 911 before calling us.
