Gas Furnace: 10 Tips for Maintenance

Share This Post


Regular maintenance will help increase the life of the furnace. Additionally, substandard maintenance can be dangerous. Furnaces that are not properly maintained are more subject to gas leaks. Here are ten tips for keeping your gas furnace in optimum condition.


Make sure your thermostat is functioning properly.

Does your thermostat setting seem to match the temperature of the house? If your thermostat is not functioning properly, it will cause your furnace to work inefficiently. Dirt and inaccurate calibration can negatively affect the performance of a thermostat. To ensure proper calibration of your thermostat, you might consider hiring a professional.


Check the air filter.

Air filters need to be changed regularly. Neglecting to change a filter could cause the furnace to produce less heat. Most hardware stores sell furnace air filters.


Monitor the control valve.

A furnace with a control valve in the off position will not produce heat. If you find your furnace is not producing heat, check the position of the control valve.


Clean your furnace regularly.

Furnace cleaning should be part of regular maintenance activities. A dirty furnace can decrease efficiency. The filter system, blower and motor need to be kept clean.


Check the tension belt.

A misaligned tension belt can cause your furnace to run loudly. If the belt appears frayed or worn, replace it with a new one.


Oil the motor.

A couple of drops of oil should be added to the furnace every season and as needed. Do not over-lubricate.


Clean the vents.

Vents should be checked regularly for debris and blockages. Blocked ventilation could cause carbon monoxide poisoning, which could be fatal.


Spring shut down.

At the end of the winter season, gas furnaces need to shut down. This is also a great time to clean the furnace and replace the air filter.


Following these tips at the beginning of each season will keep your furnace in good working condition. If you need any assistance contact us at Hearth & Home.
