CarbonCurb Action 12 - Clean Air Filter


Approximately half of your total energy consumption at home is for heating and cooling air so that you can enjoy a comfortable, and relatively steady temperature year-round.  Since your heating, ventilation, and air conditioning (HVAC) system account for such a large share of your energy use and annual GHG emissions, it is very important to become mindful of how your comfort preferences impact not only your bank account, but the world around you, and how to better maintain your HVAC system. Your HVAC system has an air filter that is responsible for maintaining healthy indoor air quality. This air filter collects dust and other particulate matter, providing you with clean, refreshing air. If you don't change your air filter frequently enough and your air filter becomes clogged with debris, you will start to notice dust collecting in your home and even an increase in your utility bills, due to your HVAC system having to work harder to force air through the filter. At a minimum, you should check to see if your air filter needs replacing once every three months (and perhaps more frequently during the peak heating and cooling seasons). This will improve the energy efficiency of your HVAC system. Set a calendar reminder, enjoy clean air, and benefit from the savings. The impact of committing to Action 12 is:

Annual Savings:
30 kg CO2e
0.2% of your GHGs
