November is a busy month for furnace repair calls. As the temperature continues to drop, heating systems have to run continuously to keep homes warm and comfortable. While there are a number of reasons you could run into furnace problems, too often we’re called in for service when the issue could have easily been prevented by regularly checking and changing the furnace filter.
Operating a furnace with a clogged filter restricts airflow, which can make the furnace extremely inefficient to run, causing breakdowns and decrease indoor air quality. We recommend that homeowners check filters every month and replace them as needed.
How to Know When a Furnace Filter needs to be replaced
Filters have different life spans based on their size. For example, a 1” filter will last about one to two months, while a 6” filter can last up to a year. However, factors such as pets in the home, running the fan continuously or smoking inside can require changing the filter more frequently.
The best way to check if the filter needs to be replaced is to remove it from the furnace and see if it’s grey in color and filled with dust and debris. If the filter is full and you cannot see through it, it’s time for a filter replacement. Always make sure the filter you’re using is compatible with your heating system. Refer to the furnace’s operating manual for more information.
We know that homeowners have a lot to worry about and changing filters likely isn’t high on the to-do list, but getting in the habit of checking filters monthly can significantly reduce the chance of running into furnace problems.
