                                                OUR STORY
The year was 1938. It was the waning years of the Great Depression. Franklin Roosevelt was our president.  And a young man, Walter Mehrholz, scraped together all his money and opened a business servicing and repairing boilers, heating units and air conditioners, becoming one of the area's first Bryant dealerships.  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 furnaces, air conditioning, boilers, air purifiers, humidifiers, ventilation, water heaters... and provides expert equipment installation, tune-up and repair services.  We look forward to being of service to you.  Thank you, Robbie Mehrholz, President
