HVAC Repair Rogers MN | Call Heating and Cooling Techs

Common signs include a strange, metallic smell when the furnace runs, soot buildup around the burner assembly, visible cracks or rust on the furnace itself, and moisture or corrosion on interior vents. Most critically, a carbon monoxide detector alert is a major red flag. If you notice any of these, shut off your furnace immediately and call us for a safety inspection.

We recommend an annual professional furnace tune-up and safety inspection, ideally in the fall before heating season. Minnesota's cold winters mean your system works hard, increasing wear. Our thorough inspection checks the heat exchanger, burners, flue, and other components for cracks or faults that could lead to dangerous CO leaks, giving you peace of mind all winter.

A cracked heat exchanger is a serious safety hazard and cannot be reliably repaired—replacement is required. For safety and efficiency, we typically recommend replacing the entire furnace. A modern, high-efficiency unit will not only eliminate the CO risk but also provide significant energy savings, better comfort, and reliability for your Rogers home.
