Due to his diligence I feel confident that our furnace will be ready and operate as expected this coming winter. Thank you Doornbos for having such outstanding technicians as Mike”

“Doornbos is the best. I’ve used several HVAC companies to service my two homes before switching to Doornbos. I’ve been a customer for about 9 years. Unlike the others, Doornbos always arrives on time, delivers great workmanship, cleans up, provides thorough diagnosis and always with a great attitude. I’ve used them for new installation and recommend their maintenance program, too. I completely trust Mike D., my technician. He’s very thorough, very technically competent, always correct on his diagnosis, has any necessary parts on his truck and glad to offer helpful homeowner type tips. Very friendly, yet professional. I hope he will continue to serve the Darien and Downers Grove area.”

“Mike Donahoo was and has been our service technician for all semi-annual checks except one. In fact, he is the person that came by to show us the types of HVAC systems available when we bought ours from Doornbos. He is always very friendly, knowledgeable and efficient. This time, he checked our furnace, cleaned it and made sure everything was working properly before he left. He advised us when to change our air filter, since we just changed it on 7/1. We were told that we were his second stop and that he'd be at our home between 9 and 10 a.m. and he was here at 9:30. We appreciate that we got a call from the office when he he was on his way. Thanks for employing great technicians!”
