How to Change your Air Filter

Home Maintenance Guides

As your heater and air conditioner run, air is cycled through your house via a system of ducts. Before passing through the ducts, air must pass through the air filters which trap airborne dust particles. Over time the air filters get clogged with dust and make it more difficult for air to pass through. Changing your filters regularly helps improve the efficiency of your HVAC unit, keep your air clean and save energy, which saves you money down the line!
