A jet wash service, often referred to as pressure washing, involves using a high-pressure water spray to clean surfaces such as buildings, vehicles, industrial equipment, and more. It is commonly used to remove grime, dirt, mold, and other contaminants. In the context of your business, you could offer jet wash services to clean air conditioning units, AHU coils, and chillers, which helps improve performance, longevity, and energy efficiency. Keeping these units clean is essential to maintain proper airflow and prevent breakdowns.
