Scope of Work
The Peerless Series SC commercial steam boiler has been a cornerstone of Chicago building heating for decades. When a large apartment building or commercial property needs a reliable, cost-effective steam boiler replacement, the SC Series is one of the most trusted options available. D's Air & Heating, Inc. has installed and replaced numerous SC Series boilers throughout Chicago's North Side, West Side, and South Side neighborhoods.
One of the key advantages of the Peerless SC Series is its cast-iron sectional design. Unlike welded steel boilers, cast-iron sectional boilers can be disassembled and reassembled in tight boiler rooms — a critical feature in Chicago's older building stock where access is often limited.
Steam heating systems remain common throughout Chicago's older residential and commercial building stock. The Peerless SC Series is specifically designed to integrate with existing steam distribution systems, making it the preferred replacement choice for buildings with established steam infrastructure.

Why D's Air & Heating, Inc. for Commercial Boilers
About Peerless Boilers
Peerless Mfg. Co. has been manufacturing cast-iron boilers in the United States for over a century. Founded in the early 1900s, Peerless built its reputation on the durability and reliability of its cast-iron sectional boilers — products that have heated Chicago apartment buildings, schools, churches, and commercial properties for generations. The Peerless name is synonymous with heavy-duty commercial steam heating in the Chicago market, and for good reason: properly maintained Peerless boilers routinely provide 40 to 60 years of reliable service.
Steam Boilers vs. Condensing Boilers — Which Is Right for Your Building?
The choice between a traditional cast-iron steam boiler and a modern condensing hot water boiler depends on several factors, including the existing heating distribution system, the building's energy efficiency goals, and the available budget. For buildings with existing steam radiator systems, replacing the boiler with a compatible steam unit — such as the Peerless SC, 64, or 211A Series — is typically the most cost-effective approach. For buildings looking to convert from steam to hot water heating, or for new construction projects, the Peerless PUREFIRE condensing boiler offers significantly higher efficiency and lower operating costs.
Chicago Steam Heating Systems — A Legacy of Reliable Heat
Chicago's older building stock — particularly the two-flats, three-flats, and six-flats that define the city's residential neighborhoods — was built with steam heating as the standard. Steam heat was the dominant residential and commercial heating technology from the late 1800s through the mid-20th century, and Chicago's building stock reflects this history. Today, tens of thousands of Chicago buildings continue to rely on steam heating systems, and the demand for experienced commercial steam boiler contractors remains strong.
Peerless vs. Weil-McLain, Burnham & Crown — How Do They Compare?
When evaluating commercial steam boiler options, building owners and property managers frequently compare Peerless against other leading manufacturers including Weil-McLain, Burnham, and Crown. All four manufacturers produce quality cast-iron sectional steam boilers with similar efficiency ratings and comparable service lives. D's Air & Heating, Inc. installs and services all major commercial steam boiler brands, and we can provide objective guidance on the best option for your specific building and application.
Emergency Commercial Boiler Replacement in Chicago
A failed commercial boiler in the middle of a Chicago winter is a genuine emergency. Tenants and building occupants depend on reliable heat, and a boiler failure can create legal liability for building owners and property managers who fail to restore heat promptly. D's Air & Heating, Inc. provides emergency commercial boiler replacement services throughout Chicago, with same-day site visits available for urgent situations.
Commercial Boiler Preventative Maintenance — Protecting Your Investment
The best way to avoid an emergency boiler failure is a proactive preventative maintenance program. D's Air & Heating, Inc. offers commercial boiler service agreements that include annual inspections, cleaning, and tune-ups designed to identify and address potential issues before they become failures. A well-maintained commercial boiler operates more efficiently, consumes less fuel, and lasts significantly longer than a neglected unit.

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.
