Our Story

Keeping Chicago Comfortable Since 1974

Engler Heating & Air Conditioning was founded in 1974 by John Engler, a dedicated craftsman who believed in doing things the right way—honest work, fair prices, and treating every customer like family. Starting from humble beginnings in the Chicagoland area, John built a reputation for reliable heating and cooling service that Chicago homeowners and businesses could count on, no matter the season. His commitment to quality and integrity laid the foundation for everything we do today.

Over the decades, the business has stayed true to its roots as a family-owned operation. After John, the company passed to his son Bradley Engler, who now leads as owner and president. Brad has carried forward the same values of transparency, hard work, and long-term relationships that defined the early years. Today, the third generation is actively involved: Brad’s son, Aaron, works as a skilled technician in the field, bringing hands-on expertise to every job, while his daughter Abra manages the operations, ensuring smooth communication and exceptional customer care from start to finish.

What sets Engler apart isn’t just our 50+ years of experience; it’s our unwavering focus on people.  We build trust through transparent pricing, same-day service when possible, and a team of dedicated technicians who know our customers by name. Chicago families and local businesses keep coming back because they know they’ll get honest advice, professional installations, and lasting repairs.

We’re proud to serve the Chicagoland Area with the same neighborly spirit that started it all back in 1974. When you choose Engler, you’re choosing a family legacy dedicated to keeping your home comfortable and your trust intact. Why Chicago families trust Engler — because we’re not just in the HVAC business; we’re in the relationship business.
