Founded in 1990 by HVAC veteran Michael Grayson, the company has grown from a small family-operated business to a leading provider of heating and cooling solutions across the Chicagoland region.
Humble Beginnings
What started as a one-man operation in a garage in Northbrook, IL, quickly expanded as word spread about Guardian’s exceptional service and technical expertise. Michael’s commitment to customer satisfaction and attention to detail became the cornerstone of the company’s philosophy, a tradition that continues to this day.
Expanding Horizons
As Guardian’s reputation grew, so did its service area. From its origins in Northbrook, the company expanded to serve neighboring communities such as:
- Lincoln Park
- Skokie
- Glenview

This growth allowed Guardian to bring its top-notch AC service, air conditioner repair, and HVAC installation to a wider range of customers, from residential homeowners to commercial properties.
Adapting to Change
The HVAC industry has seen significant technological advancements over the years, and Guardian has consistently stayed ahead of the curve. By investing in ongoing training for their technicians and adopting the latest energy-efficient systems, the company has positioned itself as a leader in modern climate control solutions.
Community Involvement
Guardian Heating & Cooling has always believed in giving back to the communities it serves. The company regularly participates in local events, sponsors youth sports teams, and offers discounted services to senior citizens and veterans.
