A furnace is one of the essential pieces of equipment that is responsible for heating your home during the winter season. However, like any other mechanical system, furnaces require regular maintenance to function at their best. Neglecting your furnace can result in costly repairs or even replacement.

How to maintain the furnace?

Replace air filters regularly

The air filter is an important component of your furnace, and it is responsible for removing impurities from the air before it is heated and circulated throughout your home. A dirty or clogged air filter can cause the furnace to work harder, which can lead to higher energy bills and reduced efficiency. It is recommended to replace the air filter every 1-3 months, depending on the level of usage and the type of filter.

Clean the furnace

Dirt and dust can accumulate in and around the furnace, which can affect its performance. You can use a soft brush or a vacuum cleaner to remove any debris from the furnace, including the blower, burners, and motor. It is important to turn off the furnace before cleaning it and to ensure that all electrical connections are secure.

Check the thermostat

The thermostat is responsible for regulating the temperature in your home, and it is important to ensure that it is functioning properly. You can test the thermostat by turning up the heat and monitoring whether the furnace turns on and off accordingly. If you notice any issues, you may need to replace the thermostat or have it repaired by a professional.

Inspect the ductwork

The ductwork is responsible for distributing heated air throughout your home, and it is important to ensure that it is free from any leaks or damage. You can inspect the ductwork for any visible signs of damage or wear and tear, and you can also check for any air leaks by using a smoke pencil or a thermal imaging camera.

Schedule annual maintenance

Regular furnace maintenance is essential to ensure that your heating system is functioning efficiently and effectively. It is recommended to schedule an annual maintenance check-up with a qualified HVAC technician, who can inspect and clean the furnace, check the electrical connections, and ensure that all components are functioning properly.
