A dirty or clogged air filter restricts airflow both into the furnace and throughout your home. That’s why checking and changing your furnace’s air filter regularly, along with performing annual maintenance, is the key to keeping your system’s heart healthy.
Annual check-ups are essential, especially as your furnace ages. Remember, your furnace is working 24 hours a day in the coldest Chicago winters. Parts will begin to wear out and need to be replaced. The qualified technicians at Air-Rite test the electrical components, check the heat exchanger for carbon monoxide leaks, and will recommend any necessary repairs to help prevent inefficient operation and future equipment breakdown.
If a breakdown occurs, sometimes you can fix it yourself by changing the furnace’s air filter or resetting the breaker. If that doesn’t work, you may need to turn the system off and back on again. The on/off switch is often found at the furnace. While you can try these things to get your furnace running again, a dirty flame sensor, plugged burner, or faulty electrical components should be left to a trained HVAC technician to diagnose and repair.
