Best Heating & Air Conditioning / HVAC In Hoffman Estates

“I’m a huge fan!! Mark, Kelsey, Chris, Omar and the entire On the Mark team are AMAZING! I’m a new homeowner and quickly discovered the HVAC system was in terrible shape. Faulty fuses caused my air conditioning to fail in the summer and my heat to go out in the winter! It was a nightmare! When I contacted On the Mark Heating and Air, everything changed. From the moment I met Mark, the owner, and his team, I knew I was in great hands. After several emergency repairs, we decided it was time to replace the entire system. Mark sat down with my wife and I to have an honest, straightforward conversation about my options and recommended the perfect high-efficiency system for my family’s needs. “The best and most efficient system on the face of the Earth” as Mark put it. And right he was!! 3 years later and is still running strong. He even provided a temporary A/C unit to keep us comfortable while the new system was being installed, that kind of service is rare these days. His technician Chris and the whole crew were professional, respectful, and detail-oriented every step of the way. I also joined their member program, which includes great discounts on parts and service plus a 29-point inspection with every tune-up. The peace of mind alone is worth it. If you’re looking for reliable HVAC installation or repair in the area, On the Mark Heating and Air is the company to call. They’ve earned my full trust and my highest recommendation.“

“New boiler installation. Extremely knowledgeable and professional installation. I highly recommend Suburban Boiler.“

“When our AC went out the day before July 4th, Matt and Integrity Heating and Air Conditioning went above and beyond to get us back up and running again. He diagnosed the problem quickly when others couldn’t seem to figure it out. Then he made a special trip to Joliet to pick up our materials before the distribution center closed on the 3rd and gave up his holiday to install a new unit…all so we wouldn’t have to wait a week to have air conditioning! They got here early and kept working till it was done. We would highly recommend Integrity Heating and Air Conditioning.“

“I have used Luke and team multiple times for my house and my one rental house. They have been upfront and honest in their communication and work. Communicating options and recommendations based on the situation.“

“Albert, is the best HVAC around. Been with him since 2020. Without question consummate professional and overall nice guy. I highly recommend 10 out of 10.“
