Gas Furnace Maintenance in Homer Glen, IL 60491
“I called after 5pm on a Friday for service on my gas furnace. The dispatcher on the phone was very helpful and seemed delighted to help me with getting someone out to take a look at my issue. I received a phone call from the Tech (George). He was very attentive to listening while I told him what the furnace was doing. I had a very pleasant conversation and George who was willing to come out and take a look at the furnace on a Friday evening. He arrived almost exactly the time he told me he would over the phone (Amazing) . George had great customer skills and was a one of the most positive techs I've met. He was super knowledgeable on everything from the furnace, humidifier, Nest thermostat, and controls. George deserves great recognition for not only a great Tech and knowledge within his job, but also as a person with a great attitude and personality.
Thanks George and Doornbos”

“Excellent turnaround. Doornbos provided heaters to help us in the interim to keep the main rooms in the house warm. The installers were very polite and explained to my husband what he needed to know about the furnace, etc. Doornbos is coming back in the Spring to complete the air conditioner installation. We would recommend Doornbos.”
