I needed service when my air conditioner stopped working. I had heard a lot of good things about Doornbos on WGN, and I decided to go with a company that specializes in HVAC. Wise choice! Doornbos diagnosed the problem immediately - a connection mistake made by someone from a different agency. Being able to speak to a live human when I called to make the appointment, getting an appointment more quickly than I had expected, and having a tech who was so knowledgeable and efficient have convinced me I made the best choice for my home HVAC needs.

Reviews
Doornbos has taken excellent care of our HVAC system for the last 30 years and continuing with this week’s A/C service.
Doornbos installed our high efficiency furnace and A/C in 2012 which has been trouble free ever since.
Always very satisfied with the maintenance service I receive from Doornbos. Ashley is very thorough and explains her findings clearly. Relatively new unit, so don’t really expect any issues, but it gives me peace of mind having a maintenance contract. With all of the recent storms and power outages, glad I bought surge suppression for the unit and compressor.
