Boiler problems can quickly disrupt comfort in Chicago homes, especially during freezing winter months. At D's Air & Heating, we provide fast, professional boiler repair for hot-water and steam systems, including Lennox, Weil-McLain, Burnham, Crown, Dunkirk, and more. Chicago buildings rely heavily on hydronic heating, and when a boiler stops producing heat, leaks, makes loud noises, or struggles to maintain pressure, our technicians deliver accurate diagnostics and manufacturer-approved repairs to restore safe, reliable operation.
Our boiler repair service covers circulator pump failures, zone valve issues, ignition problems, pressure irregularities, air in the system, thermostat malfunctions, leaking components, and sediment buildup. We inspect the heat exchanger, test safety controls, evaluate venting, check expansion tanks, and verify proper water circulation. Whether your radiators aren't heating, your boiler is short-cycling, or you're experiencing low pressure, we provide clear pricing and fast service to get your system running efficiently again. If your system is beyond repair, our team also handles boiler installation with free estimates and financing available.
We also specialize in boiler performance restoration, including system flushing, pump replacement, air elimination, radiator balancing, and hydronic system optimization. For Lennox boiler equipment, our technicians follow Lennox-approved service procedures. With proper repair and maintenance from D's Air & Heating, your boiler will deliver steady, quiet, and efficient heat throughout Chicago's coldest months. Contact us to schedule service today.

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.
