When your heating or cooling system quits on you, you need help fast. In southern Illinois, a broken air conditioner in the middle of July or a furnace that stops on a freezing January night is more than an inconvenience, it can disrupt your whole household. At Collards, we provide prompt, reliable HVAC repair services for homes and light commercial spaces across Williamson, Franklin, and Jackson counties. Whether you are in Carterville, Herrin, Marion, or one of our many surrounding communities, we get your comfort restored quickly and correctly.
Why Timely Repairs Matter in Our Area
Our weather changes fast. One day you are running the air conditioner, the next you are kicking on the heat. That kind of back-and-forth puts strain on your HVAC system. Small issues can turn into big problems if they are ignored, especially during the extreme temperatures we see in places like Benton and Carbondale. Addressing problems right away saves you money and prevents further damage to your equipment.
Common HVAC Problems We Fix
Lack of Heating or Cooling If your system is running but not delivering warm or cool air, it could be a refrigerant leak, a failing compressor, or a problem with your thermostat. Uneven Temperatures Hot and cold spots in your home might be due to ductwork issues, blocked vents, or a malfunctioning blower motor. Strange Noises Banging, grinding, or squealing sounds often signal loose parts, worn belts, or motor problems that need immediate attention. Frequent Cycling If your system keeps turning on and off, it could be a sign of electrical issues, a clogged filter, or incorrect system sizing. Unusual Odors Burning smells, musty odors, or a hint of gas should never be ignored. They may indicate electrical issues, mold growth, or a dangerous leak.
Our Repair Process
Thorough Diagnosis – We pinpoint the exact cause of the problem using advanced testing tools and years of hands-on experience. Clear Recommendations – We explain your options and the cost before any work begins. Expert Repair Work – Our trained technicians handle repairs efficiently so your comfort is restored quickly. Post-Repair Testing – We run the system through a full cycle to confirm everything is operating properly.
Emergency Service for Urgent Situations
When extreme weather hits and your system stops working, waiting until the next business day is not an option. That is why we offer prompt emergency repair service to get your heating or cooling running again as quickly as possible.

Wonderful team! The office team got us scheduled the very next day. Our tech Tyler came out, figured out the issues with our unit and very patiently explained everything that needed to be done before handling the issue. 10/10 highly recommend.

Tyler came out on time and fixed my AC the same day at a good price. I had a different company look at it and they said it needed a new system. Glad I got a second opinion. Thanks for being good and honest!

Doug came out today for our annual furnace inspection. He did exceptional work getting everything cleaned and tuned up, and he gave us valuable insights on equipment failures that are likely to be upcoming due to the advanced age of our unit.

Our newer furnace had stopped working in the middle of the night. I called early and they were able to come out same day and get it going again. Paid for parts and service and they will be back with the new part in just a few days. Happy with service.
