Weil-McLain Steam Boiler Installation in Chicago
Chicago's older residential and commercial building stock relies heavily on steam heat. Two-pipe and one-pipe steam systems are common in the city's greystones, two-flats, and vintage apartment buildings. D's Air & Heating, Inc. specializes in Weil-McLain steam boiler installation and replacement throughout Chicago.
The Weil-McLain EG Series and CGa Series handle residential steam applications. The 88 Series and LGB Series serve large commercial steam loads — apartment buildings, schools, churches, and industrial facilities. All are available in gas-fired configurations.
Steam system installation requires specialized knowledge of steam pressure, venting, piping pitch, and near-boiler piping configuration. D's Air & Heating, Inc. technicians are trained in steam system installation and understand the specific requirements of Chicago's older building stock.
D's Air & Heating, Inc. handles every aspect of the steam boiler installation — permit, removal, installation, near-boiler piping, venting, controls, startup, and city inspection. We do not subcontract. Call (773) 940-0965 for a free in-home estimate.

Frequently Asked Questions — Weil-McLain Steam Boiler Installation
What Weil-McLain steam boiler models does D's Air & Heating install?
D's Air & Heating, Inc. installs the Weil-McLain EG Series and CGa Series for residential steam applications, and the 88 Series and LGB Series for large commercial steam applications including apartment buildings, schools, and industrial facilities.
How is a steam boiler sized differently from a hot water boiler?
Steam boilers are sized based on connected radiation load (EDR — equivalent direct radiation), not square footage. D's Air & Heating, Inc. performs a proper EDR survey of your existing radiators to ensure the new boiler is correctly sized. An oversized steam boiler causes water hammer, wet steam, and wasted fuel.

Yes. The City of Chicago requires a mechanical permit for boiler installation. D's Air & Heating, Inc. pulls all required permits and coordinates the city inspection. IL License #2183457.
