Chicago Heating & Cooling Done Right.
You've Tried Da Rest. Experience the Difference with D's Air & Heating.
Serving homeowners and businesses throughout Chicago and surrounding communities.
Boiler replacement is one of the most important upgrades for Chicago homes that rely on hydronic heating. At D's Air & Heating, we provide professional boiler replacement for hot-water and steam systems, including Lennox, Weil-McLain, Burnham, Crown, Dunkirk, and other leading brands. Chicago winters demand strong, consistent heat, and an aging boiler can lead to high gas bills, uneven heating, leaks, loud noises, and frequent breakdowns. A properly installed new boiler restores comfort, improves efficiency, and ensures reliable performance throughout the coldest months.
Our boiler replacement process includes full system evaluation, proper sizing, circulator pump setup, zone valve configuration, venting upgrades, expansion tank installation, and complete hydronic balancing. We remove the old boiler, install the new system according to manufacturer specifications, and perform full startup testing — including combustion checks, water pressure verification, air purging, safety control testing, and radiator or baseboard confirmation. Whether you're upgrading to a high-efficiency condensing boiler or replacing a standard unit, we deliver clear pricing, fast service, and professional workmanship. If your system only needs service, our boiler repair team is available same-day.
We also specialize in multi-unit boiler replacements, ensuring apartment buildings and multi-family homes receive balanced heat, proper zoning, and long-term reliability. For new construction or add-on systems, see our boiler installation page. With expert installation and routine maintenance from D's Air & Heating, your new boiler will deliver quiet, efficient, and dependable heat for years to come.

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.
