Denny's Heating Cooling & Refrigeration Service - Troy's Local HVAC Services

A frozen HVAC component, often caused by restricted airflow or refrigerant issues, is a common problem in our climate. First, turn your system off at the thermostat to prevent damage and allow it to thaw completely. Check and replace dirty air filters, as this is a frequent cause. For persistent freezing or if you notice ice on the refrigerant lines, it's best to call for service. Our technicians can diagnose the root cause—whether it's a refrigerant leak, a faulty blower, or a dirty coil—and provide a reliable repair to restore your comfort and system efficiency.
