Gibeau Heating & Cooling | Reliable HVAC Services in Grand Rapids, MN

Ice buildup on your outdoor unit is a common issue in our cold, humid climate and usually indicates a problem like low refrigerant, a dirty air filter, or a failing defrost cycle. While the ice itself can damage the coils and internal components, the bigger concern is that your system is working inefficiently, driving up energy costs. It's best to turn the system off and call for service to prevent further damage. Our technicians can diagnose the root cause and perform the necessary repair to restore proper operation.

The most important step is to schedule an annual furnace tune-up and safety inspection before each heating season. Our technicians check for cracks in the heat exchanger, ensure proper venting, and test for CO leaks—common issues with older systems. We also strongly recommend installing CO detectors on every level of your home, especially near sleeping areas. If your detector alarms or you notice symptoms like sooty stains around the furnace or a yellow burner flame instead of blue, shut off the appliance immediately and call us for an emergency inspection.

A pre-winter maintenance visit from our team is the best preparation. We perform a comprehensive check including cleaning the burners and heat exchanger, testing safety controls, checking airflow, and lubricating moving parts. For homeowners, we recommend replacing your furnace filter monthly during heavy use, keeping all vents clear of snow and debris, and ensuring nothing flammable is stored near the furnace. This proactive care improves efficiency, prevents mid-winter breakdowns, and is crucial for identifying potential carbon monoxide hazards before they become dangerous.
