Your indoor air quality is a major component of maintaining a healthy and comfortable living environment. Your home’s air conditioning (AC) unit plays a significant role in determining IAQ. At A/C King Inc., we recognize the intrinsic link between indoor air quality and AC units. 

Filtration Efficiency

AC units are equipped with air filters that help trap dust, pollen, pet dander, and other airborne particles. These filters play a crucial role in improving IAQ by capturing pollutants before they circulate throughout your home. With usage over time,  filters can become clogged, reducing their effectiveness. Regular filter replacement or cleaning is essential to maintain optimal filtration efficiency and ensure clean indoor air.

Humidity Control

Proper humidity levels are essential for indoor comfort and IAQ. AC units help regulate humidity by removing excess moisture from the air during the cooling process. High humidity can promote mold growth and worsen respiratory issues, while low humidity can cause dryness and discomfort. 

Modern systems often include humidity control features to maintain ideal indoor humidity levels, enhancing IAQ and overall comfort.


AC units play a role in ventilation by circulating and exchanging indoor and outdoor air. Proper ventilation is crucial for diluting indoor air pollutants and replenishing oxygen levels. However, poorly maintained AC systems or inadequate ventilation can lead to indoor air stagnation and the buildup of pollutants, compromising IAQ. Regular AC maintenance and proper ventilation system design are essential for promoting healthy indoor air circulation.

Airborne Contaminant Removal

In addition to filtering out particulate matter, some AC units are equipped with advanced filtration systems that can capture smaller particles, helping to trap bacteria, viruses, and volatile organic compounds. These systems provide an extra layer of protection against airborne contaminants, further enhancing IAQ and safeguarding the health of occupants.
