How Often Should Furnace Cleaning Be Done?

Regular furnace cleaning is crucial, especially for first-time owners. Annual cleanings are recommended, with some times of year being optimal. Here are some tips.

A furnace installation is an effective way to ensure a home is heated properly for decades. Once installed, the maintenance is straightforward without the need for logs, coal, or other fuel, and there's no concern about returning to a cold house. However, periodic furnace cleaning is necessary. Many families have observed a gradual decrease in furnace energy efficiency. This decline is preventable; a well-maintained furnace should retain its efficiency throughout its lifetime.

When and How Often Should a Furnace Be Cleaned?

Those who have previously installed a furnace understand the importance of regular cleaning. For first-time owners, it may not be as apparent. Most manufacturers and installers recommend that the furnace be cleaned at least annually. Furthermore, certain times of the year are more suitable for cleaning, which might be counterintuitive. Here are some tips for furnace cleaning:

Clean the Furnace at the End of Winter 

The furnace is used heavily during the cold winter months. Starting winter with cleaning is unnecessary unless it is extremely dirty or has been neglected for years. Throughout winter, the furnace circulates numerous dust particles and dirt, which accumulate in the air ducts and components. The ideal time for cleaning is right after winter to prevent this debris from settling during the warmer months.

More Often is Better than Less 

In warmer areas, an annual cleaning is typically sufficient. However, in colder regions where furnaces are used more extensively, more frequent cleaning might be necessary. This doesn't mean skipping cleaning after a mild winter is acceptable!

Neglecting Furnace Cleaning Can Be Costly 

A furnace clogged with dirt and dust over the years can break down, with nearly a quarter of furnace repair calls being for severely malfunctioning units. A dirty furnace also becomes less efficient, increasing fuel usage and energy bills each year. Neglecting cleaning in an attempt to save money often results in higher costs in the long run.

Scheduling annual furnace cleaning is crucial, regardless of how long the furnace has been installed. Marking the calendar to remind oneself of the cleaning date each year can prevent future expenses and inconvenience. For those who have recently purchased a furnace, it's advisable to inquire with the contractor about their cleaning services or request recommendations from reputable cleaners.
