Frequently Asked Questions

Boiler Maintenance — Chicago FAQ

How much does a boiler tune-up cost in Chicago?

D's Air & Heating charges $129 for a standard hot water or steam boiler tune-up. A Technical Visit — $95.35 applies to all appointments. Steam boiler maintenance is priced by BTU output: Tier 1 (up to 150,000 BTU) $129, Tier 2 (up to 300,000 BTU) $199, Tier 3 (300,000+ BTU) $299.

How often should a boiler be serviced in Chicago?

Once a year — ideally in early fall before the heating season begins. Annual maintenance catches small problems before they become expensive repairs, keeps your system running at peak efficiency, and satisfies most manufacturer warranty requirements.

What does a boiler tune-up include?

Our boiler tune-up covers burner cleaning, flame sensor cleaning, ignitor inspection, circulator pump check, zone valve check, pressure check, expansion tank inspection, pressure relief valve test, venting inspection, safety control testing, thermostat calibration, and a light system flush. Steam boiler service also includes pressuretrol testing, radiator vent inspection, water level check, low-water cutoff test, and sight glass inspection.

Do you service all boiler brands?

Yes. We service all major boiler brands including Weil-McLain, Burnham, Dunkirk, Crown, Peerless, Lennox, Navien, Noritz, Thermoflo, and more. No service contract required.

Do you service steam boilers in Chicago?

Yes — steam boiler maintenance is one of our specialties. Chicago's older housing stock (bungalows, greystones, two-flats, and three-flats) relies heavily on one-pipe and two-pipe steam systems. We service all steam boiler brands and sizes, with BTU-tiered pricing to match your system's output.

What is a boiler system flush and when do I need one?

A boiler system flush ($199) removes sediment, rust, and mineral buildup from the water in your hydronic system. You may need one if your boiler is noisy, circulation is uneven, or the water in the system appears dark or rusty. We recommend flushing every 3–5 years or whenever sediment is found during a tune-up.

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.
