Why Steam Matters in Chicago
Chicago's two-flats, greystones, and bungalows were built for steam heat. The radiator infrastructure is already in place — replacing it with forced air means tearing out walls, running ductwork, and losing the even, radiant comfort that steam delivers.
D's Air & Heating, Inc. specializes in steam systems that most HVAC contractors won't touch. We understand single-pipe vs. two-pipe configurations, pressuretrol settings, main vent sizing, and radiator balancing — the details that make the difference between a quiet, even system and one that bangs all night.

What Chicago Homeowners Should Know About Boiler Installation
How a Hot Water Boiler Works
A hot water (hydronic) boiler heats water and circulates it through pipes to radiators, baseboard convectors, or radiant floor tubing. The water returns to the boiler, is reheated, and recirculates. Modern condensing boilers achieve 90%+ efficiency by recovering heat from exhaust gases that older boilers waste.
Steam vs. Hot Water Boilers
Steam boilers — common in Chicago's older two-flats and greystones — heat water until it becomes steam, which rises naturally through pipes to cast-iron radiators. They require no circulator pump but need precise water level control. Hot water systems are quieter, more efficient, and easier to zone. D's Air installs and services both.
Boiler Sizing and Near-Boiler Piping
Correct boiler sizing requires calculating the heat loss of every room in the building. Oversized boilers short-cycle and cause water hammer in steam systems. Proper near-boiler piping — header design, equalizer pipe, Hartford Loop for steam — is as important as the boiler itself. D's Air follows manufacturer piping diagrams and ASHRAE guidelines on every installation.
Combustion Safety and Venting
Every boiler installation requires proper combustion air supply and flue venting. Inadequate combustion air causes incomplete combustion and carbon monoxide production. Improper venting allows flue gases to back-draft into the living space. D's Air verifies combustion air, draft, and CO levels on every installation.
