Providing Comfort and Expert Service Since 1927
Over 90 years ago, Fred Doornbos started his heating business. Fred’s philosophy was to do only quality work and the referrals would eventually keep him busy. Fred was right. One job led to another, and today our reputation for quality work continues, as does our philosophy. At Doornbos, it is all about quality workmanship.
We uphold the old-fashioned values which 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.
Our professional standards ensure quality results on every project Doornbos performs. Doornbos guarantees satisfaction.

“Our Carrier Air Conditioner was 25 Years old. We needed a replacement. The guys installed a new Carrier today. We are so happy with it. Both of the workers were just fantastic. They installed everything and cleaned up afterwards. Thank you Tony and his partner repairman for your hard work. They couldn't have been nicer. Also, thank you to Julie and Anthony P. Great job by all. Highly recommended.”
– Ellie J.
“Anthony was our serviceman today. He took time to explain to my son the entire operation. Explained what he was doing and how things worked and what may be ready to change out in the fall.
He checked to make sure the baseboards were functioning accurately and explained how to check them during the season.
I can’t say enough about his customer service.
You are so fortunate to have Anthony on your team.
Thanks Again.

I carefully researched companies and am completely satisfied with Doornbos performance and will use them again!”
