Furnace Maintenance Checklist: 6 Things to Do

In the winter, your furnace is one of the most essential components of your home. It takes the chill out of the cold air and improves your indoor air quality, all while being a safe option for heating your home.

To keep you and your family safe during the cold winter months, maintaining your furnace is essential. Just by servicing your furnace, you are reducing the risks of a fuel leak, increasing the efficiency of the unit, avoiding a breakdown in the middle of winter, and even keeping your warranty valid.

Fortunately, by using an easy DIY furnace maintenance checklist, you can keep your furnace in tip-top shape. If you want to maintain your furnace but aren’t sure where to start, this short and simple guide is for you.

  • Visual Inspection

The first step for an effective furnace repair is to complete a visual inspection. Look for common signs of damage as well as loose pipes or tubes. If you smell rotten eggs near your furnace, you likely have a gas leak.

  • Clean or Replace the Air Filter 

Part of regular HVAC maintenance is changing the air filter. This is essential to help your HVAC work properly and to reduce air pollution in your home. Ideally, you should change your filter every 90 days.

  • Test the Carbon Monoxide Detector 

An important task on your checklist is to test the carbon monoxide detector. This is essential because carbon monoxide poisoning can cause a range of medical issues, including death. Don’t forget to replace the batteries if necessary.

  • Clean the Flame Sensor 

The flame sensor is an essential component of your furnace that helps heat your home safely. You can clean your flame sensor by turning off the furnace, removing the sensor, cleaning off any debris with steel wool, and replacing the sensor. If the burners and sensor are not working, you might need a furnace replacement.

  • Check the Pilot Light

Without a working pilot light, your furnace will not heat your home. Check your pilot light to make sure the flame is blue. If the flame is any other color, turn the furnace off and schedule an HVAC repair.

  • Clean Around the Furnace

While most of your checklist covers the components inside of your furnace, you do need to attend to the outside as well. Make sure to clean the outside of your furnace thoroughly. Use a microfiber cloth to dust the exterior and use a vacuum to remove any remaining debris.
