When Walter Mehrholz, founder of All Temp Heating & Air Conditioning Company, first opened his HVAC business back in 1938, most Chicagoans could not imagine a future of year ’round ideal indoor comfort. But here we are, 73 years later, enjoying the most advanced air conditioning to keep us cool during hot Chicago summers, and high-efficient furnaces to keep us warm and toasty when the icy Chicago winter winds blow.

Today, All Temp is Chicagoland’s most trusted company for residential indoor comfort equipment and service, and the largest, leading Bryant dealership in the country. From Evanston to Naperville, Chicago’s south suburbs to the North Shore, All Temp’s reputation for excellence and customer satisfaction continues to grow… by the hour. With more than 659,000,000 hours on the job, few Chicago companies can claim more experience. All Temp’s highly trained technicians have solved thousands of equipment problems—repaired thousands of furnaces and air conditioners–sold and installed a multitude of comfort equipment to keep Chicagoans in their comfort zone. The service, technology and savings behind the Bryant products they sell makes All Temp the #1 choice for home comfort quality.

Yet, some things have not changed in 73 years. The company is still a family-run business, today spearheaded by Walter’s grandson, Robbie Mehrholz. And the company still offers free in-home estimates and stands behind every single sale and service they provide to Chicagoans.
