About Us

55 Years and Still the Best!

In 2024, Allied Air Conditioning & Heating Corporation became the only Illinois Carrier dealer to win the Carrier Presidents Award for the 16th consecutive year. This is accomplished through hard work, and ethical treatment of customers and employees who are all working for the common goal of being the best HVAC contractor in the area. We have the highest quality and talented individuals who work hard to earn the trust of our customers each day.

Allied Air Conditioning & Heating Corporation was founded by Brent Bauer, a University of Illinois graduated mechanical engineer, and Greg Budinger, a CPA who he met while working for a Chicago controls manufacturer Parker Hannifin. The two quickly became friends and decided to go into business together. In 1969, they incorporated Allied Air Conditioning & Heating Corporation and grew steadily. Throughout the 1970s and ’80s, they installed and serviced Carrier furnaces and air conditioners for homes and businesses in Chicago’s northwest suburbs.

During the 1980s, Chicago’s northern suburbs were growing rapidly so the partners took a risk and acquired a small dealer in Libertyville to expand the reach of Allied’s service area. With the two locations, a commitment to providing the best service and installations, and the finest Carrier equipment Allied Air Conditioning & Heating Corporation has become the go-to HVAC dealer for thousands of homes and commercial properties in Chicago’s north and northwest suburbs.

“Treating your home as part of our family since 1969” is our commitment and promise to our customers. Treating customers with honesty and providing the best products, engineering, service, and installation practices at honest pricing has made us successful. At Allied, we strive to be the company our customers want to tell friends and neighbors about. Our goal is to grow through our reputation as a trustworthy company and remain loyal to our promise.

What Our Customers
Say About Us

We moved into a new house recently and Allied was recommended to us by my best friend.

We had them install a new humidifier and zone the system. On moving day (Friday) at 3 pm when we showed up we found the AC wouldn't shut off. I texted my tech with hopes of getting on the schedule for the following week since it was late Friday. He said someone would be there in 30 min. They stayed for 2 hours and fixed a faulty wire and it was all covered under warranty. Can't argue with customer service like that. Highly recommend if you want dependable folks that are very responsive.

We were extremely pleased by the service that Allied provided us.

Our A/C went out over the 4th of July we knew we needed a new system installed asap (we knew it was on its last leg). We contacted them and two other companies for comparison quotes. Allied was out here first thing July 5th to assess and provide a quote. In the end we decided to go with them. They were professional, thorough and very detailed in options and quotes.

Moved into the neighborhood and Allied HVAC had been recommended from my brother to replace both our furnace and ac unit.

Very professional from the start with a quote from Chris B. in sales which lead to an install date of my choice. On the day of the installation Jeff and Jackson arrived right on time as requested. The installation was prompt and done in a timely matter, and it they explained exactly what needed to be done from start to finish.
