Derek Cole explains why a clean HVAC air filter matters: when it gets clogged, your system works harder, uses more energy, and wears out faster. Changing or cleaning it regularly keeps everything running efficiently.
Believe it or not, it's one of the most important things you can do for your system to be energy efficient is actually change that air filter. The air filter is taking the particles or anything in the air and blocking it from coming into the unit. Because when the unit gets dirt and dust, it has to work harder. You're spending more energy to have that unit run at the same capacity. All this leads to it working harder, failing sooner. So make sure that air filter is clean.
