Get matched with top air conditioning pros 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."

"Very impressed with their heating and air conditioning maintenance. They explained everything clearly, worked efficiently, and left no mess behind. Our home feels fresher after the air duct cleaning. Definitely a trustworthy team you can rely on."

"We had a great experience with Four Seasons Heating & Air Conditioning during our recent replacement of our furnace and AC unit. They were very professional and completed the job on time and answered all of my questions. Would recommend them for our Heating, Air Conditioning, Plumbing and Electrical needs."

"They were prompt, friendly and knowledgeable. The problem with my A/C was explained to me clearly and I was back in cool, air conditioned comfort in no time!"

"I went online Mon nite, they called me within 10 mins, came out the next day & fixed the air at a very reasonable price"

"Austin, Orin and James were great to work with. Due to raccoon damage to the attic insulation and ceiling drywall all old insulation needed to be removed and contaminated areas treated. They installed new soffit baffles between each pair of rafters, sealed all potential air leakage points (e.g. around can light fixtures), ran all new insulated bath fan ducts (4) to soffit mounted valved vents and blew in all new insulation. Cost was very reasonable. Overall excellent value. Austin provided my insurance company with all necessary information so the claim was quickly settled to my satisfaction. Highly recommend Greenlink Energy Solutions."
