Tip #3: Changing your air filter regularly can save money.
If you think you’re saving by not changing the air filter on your furnace regularly, then think again.
When an air filter becomes dirty, it restricts the amount of air that can pass through it. This makes your furnace work harder, which can reduce energy efficiency and shorten the life of your heating system.
Check the air filter on your heating system regularly, and replace it every 1-3 months. Use a quality air filter to reduce indoor air pollution and keep your home cleaner.
