Fire & Ice Heating and Air Conditioning: Certified HVAC Services Serving Chetek, WI 54728.0

Yes, uneven heating can be a sign of a cracked heat exchanger, which is a serious safety concern. A crack can allow carbon monoxide, an odorless and dangerous gas, to leak into your home's air. If you suspect this issue, turn off your furnace immediately and call us. Our Chetek technicians will perform a thorough inspection to diagnose the problem. We prioritize your family's safety and will explain all repair or replacement options clearly.

While resetting the thermostat or changing batteries is a good first step, persistent issues often indicate a deeper electrical or wiring problem within your HVAC system. DIY fixes can be risky and may void warranties. Our expert repair service will accurately diagnose if the issue is with the thermostat itself, the wiring, or your furnace/AC unit. We get it right the first time, saving you time, money, and frustration while restoring your home's comfort.

Our preventative maintenance plans are designed specifically for Wisconsin's harsh climate. During a tune-up, our technicians perform over 20 key checks, including a detailed visual inspection of the heat exchanger for early signs of stress or cracking. We also clean critical components, check electrical connections, and ensure proper airflow. This proactive care improves efficiency, extends your system's lifespan, and most importantly, identifies small issues before they become dangerous, costly emergencies during our coldest months.
