95 Years of Quality Service with Doornbos Heating and Air Conditioning

We couldn’t be more proud to be celebrating Doornbos Heating and Air Conditioning’s 95th Year of Quality Service. Our founder, Fred Doornbos, believed one successful job led to another. His philosophy was to always do unsurpassed quality work—and referrals would keep him busy.

Today, our reputation for quality work continues—as does our philosophy. These old fashion values are rooted in you—our customer. Our reputation and commitment to quality service exist because of great clients like yourself.

Thank you for supporting our business. Doornbos is here to stay, proud to build on our past to create a brighter future.

We take your comfort seriously

Your heating, ventilation, and air conditioning (HVAC) system is a significant portion of your home budget. Running a furnace, heat pump, or boiler in the winter, for example, costs the average American roughly 29 percent of their energy bill every year, according to the U.S. Department of Energy (DOE).

That’s why our team takes home comfort seriously. We want to save you money while keeping you safe and comfortable. Our NATE- and EPA-certified professionals bring a blend of expertise, fine technology, and friendly service. Whether you need an HVAC installation, repair, or maintenance, we’re here in Alsip, ready to assist. 

Doornbos Family History

Our family name stretches back to the 1800s in the business world. Initially, our family made a living by shipping ice and coal. Visit our History page, and you’ll find an old black and white photograph that shows a horse and buggy, with “Doornbos Fireproof Storage and Van Co” printed on the side. This is a testament to the longevity of the Doornbos name and dedication Doornbos has had to comfort for over 95 years. 

• Humble Beginnings 

In 1927, Fred Doornbos opened our first location in the Southtown neighborhood of Chicago. The shop was established on 93rd and Green, called “Fred Doornbos Sheet Metal Co.” 

Fred was an exceptionally driven man, working solo for the first five years of business. But by 1932, his shop had developed a sizable customer base. As a result, he began hiring technicians, including his eldest son, Bob. He told Bob, “If you’re old enough to go to school, you’re old enough to work!” 

Next, in 1944, Fred opened a second location at 8678 S. Vincennes. It was on Chicago’s South Side in the Gresham community. Known as a “one-stop-shop,” the site offered every facet of home AC and heating services––estimates, installations, repairs, and maintenance. 

• Flagship Location

In 1968, we moved to our iconic Alsip location on Cicero Road. In the same decade, Fred retired, and his son Bob moved into the owner-operator position. During the ’70s, our business expanded to about eight times its size. 

As his father did for him, Bob Sr. trained his son Bob Jr. in the art of HVAC service. Now in 2022, Bob Jr. runs the business, carrying forth the integrity and work ethic his family taught him.
