Gas Furnace Replacement in Palos Heights, IL, 60463

“We've had Doornbos service our 2 furnaces for many years so when it came time for new furnaces Doornbos was our choice. From the initial call for the estimate to the installation of both furnaces and air conditioners the staff were professional and answered my questions. Phone Representative was courteous and helpful, salesperson was very knowledgeable and communicated what was needed and how much it would cost, as well as providing information about rebates. The Installation team were professional, cleaned up and went over the new products. As a prior customer with the two year service program, I am very satisfied with the company. My furnaces were 19 & 20 years old and I'm sure that's because of the regular service that Doornbos provides. Reasons for using Doornbos include, the Doornbos Reputation, Quality products, and the informative salesperson.”

Gas Furnace Installation in Orland Park, IL, 60462

“Nick and Andy installed our new Carrier furnace yesterday. They also hauled away our 44 year old original behemoth. As you may expect, the installation required a fair amount of modification of the ductwork. The new furnace looks and works great. Nick and Andy were professional, efficient, and friendly. They took great care in maintaining the condition of our home, and when finished, swept the entire work area clean. Our salesperson, Bob, was knowledgeable and genuine. He was essential in helping us make several important choices. My wife and I believe they all did a terrific job.”

Gas Furnace Maintenance in Other, IL 60561

“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.”
