Get matched with top swamp cooler installers and replacers in Belvidere, IL

"I’ve used Carlson Heating & Cooling twice and have been very satisfied both times. In 2024, I had them inspect my furnace and AC. They arrived on time, were professional, and gave my system a clean bill of health—without recommending any unnecessary repairs. In 2005, when my AC stopped working, they quickly diagnosed a dead compressor and recommended a replacement. Impressively, they waived the $225 charge for the initial visit and parts. The replacement was completed on schedule, exactly within the estimated cost. The technicians were friendly, informative, and professional throughout the process. They also cleaned up thoroughly, leaving no mess behind. I trust Carlson Heating & Cooling completely and will continue to use them for future service. I highly recommend them to anyone needing a system check-up, repair, or replacement."

"INTEGRITY scheduled the panel replacement, called to verify the time of arrival and estimated the amount of time that the project would take.  Derek arrived on schedule, assessed what needed to be purchased from the local Home Depot to complete the project and completed the project on time.  He was friendly, courteous and very competent.  Derek is a very neat person and the area where he installed the new panel was meticulous when he left.  I wouldn't hesitate in using this company again.  A+

"Called them as A/C was not working. They came out and refreshed freon. that was $215 fee. Our A/C was old and we were advised that it may or may not last. We decided to get a new A/C as ours was 20 years old. They advised me of the different models that they work with and gave me a written estimate and let me choose. The.y also subtracted the cost of the freon from the installation cost of a new A/C. One thing that was very impressive was that they were very punctual and gave us estimated time to have work completed. We ran into many other vendors who could not seem to provide accurate information. My wife and I felt an immediate concern for our worries from Oscar. We felt our needs were met and was very happy with service provided. I appreciated the way we were treated. This is a small business that seems to go the extra mile for you."

"The cleanest my truck has ever been!! Highly recommend!"
