HVAC Services Mosinee WI | Call Central Wisconsin Heating Systems

We perform a thorough visual inspection and use specialized tools like combustion analyzers to check for carbon monoxide leaks and cracks that aren't visible to the naked eye. Catching this issue early is crucial for safety, as a cracked heat exchanger can leak harmful gases into your home's air. We provide honest assessments and clear explanations of any needed repairs.

Frozen heat pump components are common here due to our cold, humid climate, often caused by refrigerant issues, dirty coils, or a malfunctioning defrost cycle. Our technicians first safely thaw the unit, then diagnose the root cause—whether it's a low charge, a faulty sensor, or airflow problems. We fix the specific issue to prevent it from happening again and ensure efficient operation.

We recommend annual professional tune-ups before each heating and cooling season. Our maintenance includes cleaning critical components, checking refrigerant levels, testing safety controls, and inspecting the heat exchanger for early signs of stress. This proactive care helps prevent unexpected breakdowns, improves efficiency to lower your bills, and extends the life of your system.
