According to ACR, the NADCA Standard, coil cleaning should be performed on which sides?

On the upstream side only
On both the upstream and downstream sides
On the downstream side only
When the system is running

The correct answer is: On both the upstream and downstream sides

Coil cleaning is crucial for maintaining the efficiency and longevity of HVAC systems. According to the ACR (Assessment for Cleaning and Restoration) and NADCA (National Air Duct Cleaners Association) standards, it's essential to clean both the upstream and downstream sides of coils. Cleaning only the upstream side would leave contaminants on the downstream side, which can affect airflow and system performance, leading to potential problems such as reduced efficiency and increased energy costs. By addressing both sides, you ensure that the coils are free from debris and contaminants that could hinder airflow and heat exchange processes. This comprehensive cleaning approach is vital for maintaining optimal system performance and air quality.
