Established in 2008, Comfort Cavalry Heating & Air began as Antioch Heating & Cooling from the back of Kevin and Emily McGrath’s 1997 Ford Windstar. A decade later, the McGraths’ “little HVAC company” has become a mainstay in Northern Illinois and Southern Wisconsin, staffed by a stellar team of Home Comfort Heroes. We are veteran-owned and family-operated, and we are proud to serve thousands of new and returning residential and commercial customers.
Benefits of Working With the Comfort Cavalry Heating & Air Team Include:
- A legacy of family values
- Extensive training backed by NATE, EPA, and heat-exchanger certifications
- Chivalrous, high-caliber service
- Affordable Comfort Corps maintenance plans to keep your system running strong
