Vanguard HVAC Solutions
Founded in 1987, Dwight Calloway began Vanguard HVAC Solutions after noticing how many of Chicago's iconic 1920s skyscrapers had outdated or poorly maintained steam and early-air systems. With deep knowledge of vintage climate equipment, Dwight Calloway built a reputation for transparent, precise work that preserves the historic character of these buildings while ensuring modern comfort.
Every job includes a detailed, illustrated breakdown showing exactly which vintage components are being repaired or replaced.
All work on historic steam systems comes with a complete system schematic and operating guide tailored to that building’s era.
Emergency service is available for no-heat/no-cool calls, but all emergency work is billed at standard hourly rates — no surprise fees or overtime charges.
