How Often to Change a Furnace Filter

Posted: January 22, 2024

Keep the Air Filter Clean to Improve Efficiency

With proper maintenance, the average furnace can last 15 years or longer. One simple way to make sure your system reaches its life span and operates efficiently is to perform an easy, do-it-yourself maintenance task–changing or cleaning your furnace’s air filter as often as the manufacturer recommends. To be on the safe side, you should generally check the filter’s condition about once a month during the heating season and change/clean it if it looks dirty.

4 Fast Facts about Furnace Filters

  1. Filters are located either inside the furnace or inside the return air vent.
  2. Some filter models are designed to be discarded and replaced with a new one.
  3. If your filter has a plastic frame, it can be cleaned and reused.
  4. Always follow the manufacturer’s instructions and be sure to shut the furnace off before handling the filter.

Other Home Efficiency Tips to Save Money

There are many ways to conserve energy and lower your costs. Some are easy and bring you small savings, but these can add up! Others take more work and require an investment, but this can result in big returns, such as upgrading to a high-efficiency heating oil system. Here are just a few ideas to think about.

Repair Leaky Ducts

Another way to improve home energy efficiency is to get your ductwork sealed to prevent air leaks. If parts of your ductwork are leaking air, this could increase your annual energy costs by as much as 30%. Your home will also not feel as comfortable as it should be. The quality of your indoor air will also deteriorate.

We have a proven method to repair leaky ductwork. The Aeroseal process we use is designed to seal the leaks in your duct system—even the ones hidden behind walls and under your home’s insulation. These hidden areas account for about 90% of your total ductwork.

Aeroseal has been used in thousands of homes, schools, hospitals, and government installations throughout the country and the world. The process usually takes less than one day to complete and we will provide you with a “Certificate of Completion” that illustrates the before and after results. Read more about duct sealing.
