Coil Cleaning Schedule Calculator

Determine optimal coil cleaning intervals based on environment and coil condition

The operating environment significantly affects fouling rate. Restaurants and industrial settings require more frequent cleaning.
Deeper coils (more rows) trap more debris and are harder to clean. Standard: 2-4 rows, deep coils: 6-10 rows.

Higher fin density means tighter spacing and faster fouling. Typical range: 8-14 FPI. Higher FPI coils clog faster.

References: ASHRAE research indicates dirty coils can reduce efficiency 20-40%. Energy cost increase is roughly 1.5x the efficiency loss percentage. EPA recommends annual coil inspection minimum.
