Ducts are used for heating, ventilation, and air conditioning purposes, to deliver and remove air. As part of the supply air, ducts also deliver ventilation air. Air ducts help ensure indoor air quality and thermal comfort in homes, businesses, commercial spaces, franchise companies, houses and industrial plants. Air ducts need regular cleaning or they can become contaminated with dust particles, pollen and other allergens. Safety regulation standard compressed air* is blown through the air vents and pushes the dust and contaminants through the main duct line leaving behind clean, disinfected ducts throughout. The application of before/after photography visually captures the undeniable benefits of air duct purification.
