Cleaning the coils on rooftop units may seem mundane, but it’s an important job that pays off for your customers in more efficient operation and longer living equipment. And, any job that’s worth doing is worth doing right.
The first step is to determine what type of condenser coil you’re working with. You may have a sectional coil, where two or three coils are attached at one end on a common tube sheet with the coils on the other end wire-tied together. The sections are typically one-pass thick. You’ll need to split these to clean them properly.
