Core Values

Core Values

The core values of Doornbos Heating and Air Conditioning and Amber Heating and Air Conditioning are rooted in you—our customers. Customer service, customer care, customer satisfaction, and customer relationships.


From the moment you call to our follow-up after your service, your complete satisfaction is our priority.


We do this through quality service, craftsmanship, and professionalism in our work and team. Always wanting to bring you the best of the best, we utilize the latest technology in both our techniques and products. Customer health, comfort, and safety are foundational in our services and why so many customers entrust us to care for their homes.


From years of being built on referrals to friends, neighbors, and family, both businesses have grown to be leaders in the HVACR industry as well as a local household name. Doornbos and Amber have longtime loyal customers who have trusted their home services to us for decades. In many instances, service relationships span across families and generations.


Combining Doornbos and Amber was a natural choice—we both have esteemed the same core values throughout the longevity of our years in business. We look forward to building and growing together to serve you best.


The Doornbos Philosophy

Fred’s philosophy was to do only quality work and the referrals would eventually keep him busy. He was right. One job led to another, and today our reputation for quality work continues, as does our philosophy. At Doornbos Heating and Air Conditioning, it is all about quality workmanship.


We uphold the old-fashioned values that have built lifelong and multigenerational relationships with our customers. At Doornbos, we recognize that honesty, integrity, and personalized attention are as important as expert workmanship and unmatched products.


Each and every member of our team continually strives to bring you the best. As one of the oldest local businesses in the Chicago area, you can be sure we will be here to stand behind the quality and integrity of the job performance in the years to come.
