    Frequently Asked Questions

    Why is my furnace blowing cold air?

    If your furnace is blowing cold air, it is usually due to one of four common issues: a tripped limit switch (often caused by a dirty air filter), a faulty ignitor that fails to light the burner, a clogged condensate line (in high-efficiency units), or a malfunctioning thermostat. If cycling the power and changing the filter doesn’t fix the issue, you likely need a professional furnace repair to test the thermocouple or flame sensor.

    How can I improve the efficiency of my heating system?

    Improving the efficiency of your heating system can be as simple as scheduling regular maintenance. Ensure that filters are changed regularly, vents are unobstructed, and your thermostat is working properly. Insulating your home and sealing any drafts can also significantly enhance the performance of your heating system. Hoff Heating & AC offers expert advice and services to help boost your heating efficiency in O’Fallon, MO.

    How often should I schedule heating maintenance for my home?

    It’s recommended to schedule heating maintenance once a year, ideally before the winter season. Routine maintenance ensures that your system runs efficiently, helps identify potential issues early, and prolongs the lifespan of your heating system. For homeowners in O’Fallon, Hoff Heating & AC provides comprehensive heating system inspections and tune-ups.

    What is included in a professional furnace tune-up?
