Replace Air Filter
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!

Locate all your air filters. Typically the return air filters are found below your thermostat.
Unhinge the snaps keeping the filter grate shut and lower the filter grate.
Remove the old filter and discard it.
Grab your new filter and check the air flow alignments. There should be a set of arrows on the top or sides of the filter. Make sure these arrows are pointing towards the duct as you insert the new filter. Make sure the new filter fits snuggly agains the back of the internal grate.
Close the grate and fasten the snaps keeping it in place.
Repeat this process once every three months or until the filter gets fully coated in dust and stops working efficiently.
