Replacing dirty HVAC air filters will ensure that you are breathing cleaner air in your home and will also make your air conditioner more efficient, making this simple step a “win-win”. The US Department of Energy describes this as the “most important maintenance task” to ensure your air conditioner’s efficiency. The DOE estimates that replacing dirty filters will reduce your energy consumption by up to 15%. Adjust your thermostat, or use a programmable thermostat, to reduce your energy consumption and change your filter as needed–more frequently if you have pets–to maximize your comfort and minimize your environmental impact.
