History

Established in 1938.

It was the waning years of the Great Depression. New York defeated the Chicago Cubs in the World Series. Franklin Roosevelt was our president. And a young man, Walter Mehrholz, scraped together all his money and opened a business servicing and repairing boilers and heating units, becoming one of the area’s first Bryant dealerships, where he had previously worked since 1927. Walter built his business with his hands, a handshake and a promise, and his small company grew and grew. The rest is history. And thanks to my grandfather, Walter, All Temp Heating & Air Conditioning has become the first choice for tens of thousands of families throughout the Chicago and suburban areas. All Temp remains a family owned and operated company, selling quality furnaces, air conditioning, boilers, air purifiers, humidifiers, ventilation, water heaters… and provides expert equipment installation, tune-​up and repair services.
