HVAC Repair Morristown MN | Call Velzke Heating & Air Conditioning

If your furnace fails to ignite in extreme cold, first check that your thermostat is set to 'heat' and the temperature is above the current room reading. Ensure your circuit breaker hasn't tripped. If these are fine, it's likely an issue with the ignition system, gas supply, or a safety sensor—common problems in our climate. Contact Velzke Heating & Air Conditioning immediately for emergency service. Our technicians are equipped to diagnose and repair ignition failures quickly to restore heat and prevent further damage from freezing temperatures.

In Morristown, where dust and seasonal allergens can accumulate, we recommend checking your air filter monthly and replacing it every 1-3 months, depending on usage and filter type. A clogged filter restricts airflow, forcing your system to work harder, which can lead to overheating, reduced efficiency, and even breakdowns—especially during peak heating or cooling seasons. Regular filter changes improve indoor air quality and prevent costly repairs. If you're unsure, our team at Velzke Heating & Air Conditioning can advise on the best filter for your home and provide maintenance reminders.

Absolutely. Preventive maintenance is key to avoiding common winter issues like furnace failures in Morristown's cold climate. Our maintenance services include inspecting and cleaning ignition components, checking gas connections, testing safety controls, and ensuring proper airflow. We recommend scheduling a tune-up in the fall before heating season begins. This proactive approach can identify potential problems early, improve efficiency, and extend the life of your system. At Velzke Heating & Air Conditioning, we offer tailored maintenance plans to keep your HVAC running smoothly and reliably throughout the year.
