For one thing it is one of the only things you as a consumer can do to prevent issues related to your Air Conditioning system that’s not related to a technical issue. The concept of Air Conditioning uses air that passes over metal coils that are made cold using the freon gas. Because of humidity and temperature differences, moisture will begin to accumulate on these coils. Any dust particles that gets past your air filter will in effect, stick to the coils and over time restrict proper air flow.
When this happens it results in your air conditioning system working more harder and longer to achieve its thermostat setting. Therefore, more energy costs to run the system.
Over time problems start to accumulate. With most coils, cleaning them requires extraction. Costs are anywhere between $700 up to even $1500. Whereas a filter at your local hardware store will run you $5-$20 per filter.
A dirty coil begins to shorten the life of your Air Conditioner greatly. And so as the single most expensive equipment in your home, changing your filters could make all the difference in the life of your unit.
