The Journey of Heat Engineering: Keeping Chicagoland Cool Since 1975

A Legacy of Comfort and Quality

Heat Engineering has been a trusted name in heating and cooling services for nearly five decades. Founded in 1975 by John and Mary Smith, this family-owned business has grown from a small operation in Westmont, IL, to a leading HVAC company serving multiple communities in the western suburbs of Chicago.

Humble Beginnings

The Smiths started Heat Engineering with a simple goal: to provide reliable AC repair and heating services to their neighbors. Working out of their garage, they quickly gained a reputation for their attention to detail and commitment to customer satisfaction.

Expanding Services and Coverage

As demand grew, Heat Engineering expanded its offerings to include:

  • AC Service
  • HVAC Installation
  • Air Conditioner Repair
  • Heating System Maintenance

By the mid-1980s, the company had outgrown its original location and moved to a larger facility in Westmont. This allowed them to serve a wider area, including:

  • Brookfield, IL
  • Hinsdale, IL
  • Westchester, IL
  • Western Springs, IL
  • Countryside, IL

Embracing Technology

Throughout the 1990s and 2000s, Heat Engineering stayed at the forefront of HVAC technology. They invested in ongoing training for their technicians and adopted energy-efficient systems to meet the evolving needs of their customers.

A Commitment to Community

As the company grew, so did its involvement in local communities. Heat Engineering has sponsored youth sports teams, participated in charity events, and offered discounted services to seniors and veterans.

Looking to the Future

Today, Heat Engineering continues to be a family-owned business, with the second generation of Smiths at the helm. They remain committed to providing top-notch HVAC services while adapting to new technologies and environmental concerns.

From its humble beginnings to its current status as a regional leader in heating and cooling solutions, Heat Engineering has never lost sight of its core values: quality, integrity, and customer satisfaction. As they look to the future, the company is poised to continue keeping Chicagoland comfortable for generations to come.
