How often to change furnace filter

As the winter chill settles in and the days grow shorter, many homeowners start to rely more heavily on their furnaces to keep their homes warm and comfortable. Amidst the hustle of holiday preparations, it’s easy to overlook the maintenance that keeps these systems running efficiently. One common question that arises is about how often to change the furnace filter, as neglecting this task can lead to reduced air quality and increased energy costs. If you’ve ever found yourself wondering about this important piece of home maintenance, you’re not alone.

It’s recommended to change your furnace filter every 1 to 3 months, depending on the type of filter and your home’s specific conditions.

Changing your furnace filter regularly is crucial for the efficient operation of your heating system. Typically, filters should be checked every month and changed every 1 to 3 months. For standard fiberglass filters, every 30 days is a good rule of thumb, especially during the peak heating season. If you have a more advanced pleated filter, you might be able to extend that interval to every 2 to 3 months.

If you own pets, smoke indoors, or have a larger household, it’s advisable to change your filter more frequently, as these factors can contribute to higher dust and debris levels in the air. Remember, a clogged filter not only compromises the air quality but can also make your furnace work harder, leading to higher energy bills and potentially costly repairs. Keeping a schedule for changing your furnace filter can help maintain a comfortable and healthy environment in your home, ensuring your furnace runs smoothly throughout the cold months.
