Tjerlund: Certified HVAC Repair Serving White Bear Lake 55110

Key signs include a strange, chemical-like smell (similar to formaldehyde), soot around the furnace, visible cracks on the burner flames, or water leaking from the base of the chimney. This is an urgent safety issue because cracks can leak carbon monoxide—an odorless, deadly gas—into your home's air supply. If you notice any of these signs, shut off your furnace immediately and call us for a professional inspection. Our technicians use specialized tools to safely assess the heat exchanger and recommend the necessary repair or replacement to protect your family.

Heat pumps can freeze due to low refrigerant levels, dirty coils, failing defrost controls, or blocked airflow from snow or debris. When components ice over, the system can't efficiently heat your home and may shut down entirely. Our White Bear Lake technicians first safely thaw the unit, then perform a comprehensive diagnosis to find the root cause. We'll repair refrigerant leaks, clean coils, replace faulty sensors, and ensure proper airflow to prevent recurrence, restoring your system's efficiency and comfort for the cold season.

Prevention starts with professional, bi-annual maintenance. Before winter, we perform a detailed tune-up that includes inspecting the heat exchanger for early stress signs, checking refrigerant levels and electrical components in your heat pump, cleaning critical parts, and testing system safety controls. This proactive service, tailored to our local weather patterns, catches small issues before they become major repairs or safety hazards. We also provide practical tips for keeping outdoor units clear of snow and maintaining good indoor airflow to support your system's health year-round.
