Zep 20201 Foaming Coil Cleaner 20 Oz Aerosol Can

Product Description

The ZEP 20201 is a foaming coil cleaner packaged in a 20 oz aerosol can, formulated for cleaning air conditioner evaporator coils. The foaming action penetrates and lifts dirt, grease, and debris from coil fins and surfaces, helping restore airflow and heat-transfer efficiency. HVAC technicians reach for aerosol coil cleaners as a standard part of preventive maintenance and service calls. The ready-to-use aerosol format requires no mixing and delivers the foam directly to the coil surface, making it practical for both residential and light-commercial service work.

This product is designed for use on air conditioner evaporator coils during routine maintenance, system tune-ups, or service calls where coil fouling is contributing to reduced system performance. It is well suited to residential split systems and packaged units where evaporator coils accumulate dust, biological growth, and airborne debris over time. HVAC service professionals typically apply it during annual or seasonal maintenance visits.

Installation Notes

Coil cleaning should be performed by a qualified HVAC technician. Always shut off power to the air handler or furnace at the disconnect and breaker before accessing the evaporator coil compartment. Follow the product label directions for application, dwell time, and rinse or no-rinse instructions. Allow the coil and drain pan to clear fully before restoring power to the system.
