dirty ac filter = wasted energy
Air conditioners require maintenance and if your not cleaning your AC’s air filter every month then you’re not only exposing yourself to poor air quality but you’re wasting a lot of energy too. When your AC’s air filter is dirty it results in the AC working harder which is the reason why many units run inefficiently and end up costing you lots of money. Attila, brought up a very good point based off his tenure in the heating and cooling business, that majority AC air filters are never cleaned thus resulting in higher electric bills a larger environmental impact.
When is the last time you cleaned or replaced your AC air filter? Do you think keeping the filter clean will help you save money on your electric bill?
