Your air filter may be one of the most critical components of your central air conditioning system. Air filters keep your air quality high, your HVAC system clean and your air conditioner operating at peak performance.

How Air Filters Work

Central air conditioners work by sucking warm air from inside the house through the air filter into the ducts, where the air flows into the air handler assembly. There, the air is cooled and passed back through the system where it is released into the house through the air conditioning vents. The air inside the home is loaded with dust, allergens, dirt and other particles. Air filters are made from materials that allow for free air flow but block these small particles, preventing them from cycling through the system and reentering the home. This helps keep the HVAC system performing efficiently and helps prevent indoor air pollution. A professional HVAC company can provide indoor air quality evaluations to ensure that the air inside your home is as clean as possible.

AC Efficiency

When the filter is loaded with dust and other particles, the air conditioning unit has to work much harder to suck in air. This puts undue strain on the system, uses additional energy, increases the amount of your power bills and can cause premature failure of your HVAC system. Replacing the filter regularly can help the air continue to flow freely and prevent the system from working too hard. In addition to leading to energy savings, it can also lower your electric bill and put money back in your wallet.

Preventative Maintenance

Filters should be replaced every month to every three months. Different filters have different recommendations for replacement frequency. Professional HVAC companies, such as Comfort24-7 providers, can help you determine the best filter to use and how often to change it. They also offer air conditioning maintenance packages that help you avoid more expensive air conditioning repairs in the future.
