Residential Customer Testimonials

Find out what our customers are saying by reviewing the testimonials below.

“Just want to commend you a very professional job. Honesty and good service are hard to find. Bob you and your staff hit it out of the park. Jamie and Nick are great workers, neat and explained everything. No wonder you have been in business so long. Thanks again.”

— Jim Colbert

“Jim and I would like to express our thanks to you for the fine work you all did to melt the polar ice cap that used to exist in my master bedroom, and for replacing the penguin habitat in my master bath with a warm and livable place for me to get ready for work on cold mornings. I cannot believe what a difference there is in our house after the duct sealing and the new furnace installation. My only regret is that I didn’t call Dornbos earlier and have this work done many, many Chicago winters ago. We greatly appreciate all of Chuck’s good counsel during our decision-making process, especially since we were complete newbies to the HVAC-world. We have complete confidence that we made the right choices for our home knowing he was at our side.”

— Paula and Jim Fitzgerald

“My husband and I recently installed a Space Pak system. I want to let you know how pleased we were with the exceptional service we received from Chuck and his team- Louis and Jim. Although your system was much more expensive than a competitor’s, we chose Doornbos because of Chuck’s thoroughness when inspecting our house and his honest manner in describing some of the challenges of the installation and additional expenses in electrical work. As an example, the competitor suggested we could save money by installing it ourselves.

You have an excellent team, Mr. Doornbos. As I told Chuck, when we need a new furnace we will be calling him.”

— Jeanne Sencion, Chicago, IL

“Before we decided to have your company install a furnace we checked with Carrier and the Better Business Bureau. Doornbos seemed like a respectable and professional company, so that was one of the reasons we chose Doornbos. When we had a little problem, you didn’t give us a run around or a hard time. So we did make the right decision. You and all the people we dealt with were really nice. Nick fixed everything perfectly. If we can ever recommend your company to anyone, we certainly will.”

— Ray Szarzynski

“I want to let you know how happy I am that I chose Doornbos to install my Space Pak system. Nick and Vince were extremely professional and hardworking and, as you know, they finished the job ahead of schedule - a great convenience to me as I was on the verge of leaving town. The system looks great; all of the insulated tubing is neatly tucked away so I can proceed with my remodeling without any obstructions.

Thank you for having them replace that old cloth wire running from my boiler to the thermostat. I’m looking forward to trying out my new system this summer. I’m sure it’s going to be great.”

— Dawn Patitucci

“This is a “thank you“ for your thank you! I had called for you but you were not available & the young lady suggested I write.

I called Doornbos because my cousin said your company is honest and competent. He was right!! I also appreciated the gentleman who came to service my heating system. His name is Mark. I was so lucky. I told him the problem was my thermostat. In fact, I insisted that was my problem and said there was no reason to look at the furnace first as he suggested. Very nicely, but firmly, he said he needed to do his assessment properly. Well, he was right!! If he had listened to me (customer is always right . . .), I would not be sitting here all warm and toasty right now. I just wanted you to know what a great employee you have in Mark. He was friendly, courteous and above all-competent!! I was telling everyone at work about my positive experience with Doornbos. I am so glad I listened to my cousin and so glad I had the opportunity to meet Mark.”

— Karen Darr

“This letter is to let you know how pleased we were with the installation of our new furnace and air conditioner put in by Kevin and Nick. They really did a great job, not only being neat but very professional. You are fortunate to have two great men working for your company.”

— Mr. & Mrs. Mathew F. Zarich

“I have been dealing with Doornbos for over fifty years and was impressed with the service I received today. Thank you”

— Robert L. Ulatoski

"I had your company install a new high efficiency furnace, and also a new air conditioning unit on 10-21-08 at my home. The gentlemen who removed and installed these units were excellent. They worked non-stop from the time they arrived to the finished project. My wife and I are very satisfied with the new furnace and air conditioner unit. Please thank the gentlemen, who worked so hard for us. We appreciate the excellent work of these men. You are very fortunate to have such quality people working for you.”

— Terry and Carol Budds

“It was really nice of you to send your thank you note. I certainly appreciate your thoughtfulness. My opinion is that you should be the ones thanked given your rapid, professional and courteous response to successful resolution of our heating maintenance issue. It is good to have a nice warm home again especially during these cold days of a seemingly eternal winter. Be assured that in the event of any future problem here we will certainly call upon your super assistance as well as recommend it to others in such need when asked who should be contacted. It’s awfully nice to know there are still people like you out there when you need someone’s help. From our warm home, take care and God bless you all.”

— Dave Gaichas and family

“I want to let you know about David C. who came out to our house today to service our furnace. He was very pleasant and friendly and did a very thorough job. If you give out gold stars for service, David deserves a huge one.”

— Sophie Galik, Palos Hills, IL.

“Words alone cannot express our appreciation for dispatching the service technician out immediately. The water from the 2nd floor broken air conditioner was coming out my kitchen ceiling on the 1st floor and our daughter was getting married that Saturday. The situation called for quick action and attention. Thank you for saving the wedding! I told all of my co-workers to call Doornbos! They are the best!”

— Mr. & Mrs. Yodka

“My furnace went out early this morning. I contacted your service and within a short order of time was contacted by one of your technicians. I explained to him my problem and he was able to assist me with getting the furnace to operate. Your technician’s name was Jaime and I would like to thank him once again for his assistance. Doornbos always comes through and will always be my first choice in my heating and air conditioning needs.”

— Joe Kriss

“My wife and I are grateful for the superb service we received today and last night from Glenn, Nick and Kevin. They expertly installed our furnace. Thank you for keeping the great service your company has been providing its grateful customers for nearly a century.”

— Bernice and Jim
P.S. your father sold us our furnace and air conditioner in 1987. He has good reason to be proud of you.

"In the fall of last year we had central air and a furnace installed by your employees Jamien and John and we ordered it from your salesman Glenn. I am writing this letter to let you know how their service was. Your salesman Glenn was so polite and not pushy . He explained everything I asked, which helped me to make my decision. He is great. Your employees Jamien and John were also the most polite, well informed men that ever worked in our home. Also they were so neat. They cleaned up everything spotlessly and the installation of both central air and the furnace was expertly done. And they explained everything to us. You can be proud to have all three of these men working for your company. I was so impressed by them. I will always call your company for service. Thank you so much for an excellent job.”

— Mrs. W. Gragido
