Product identity

Nu-Calgon 4371-75 is a 19 oz aerosol coil cleaner formulated for heating, ventilation and air conditioning maintenance. The orange can delivers a foaming spray that penetrates fins to remove dirt and debris from evaporator and condenser coils. It suits technicians and RV owners who need a ready-to-use chemical cleaner for routine system upkeep.

Standards and handling

The product meets ANSI Z 88.2, CAN/CSA-Z 94.4 and OSHA 29 CFR 1910.134 respiratory protection references, indicating compliance with recognised safety benchmarks. The aerosol propellant dispenses the formula without external power, so no electricity or specialised equipment is required during application. The white foam colour helps the user see coverage on dark coil surfaces.

Sustained use profile

Under continuous cleaning sessions the foam maintains consistent expansion and cling, allowing extended contact time on heavily soiled coils without rapid collapse. The 19 oz volume supports multiple residential or light-commercial units before a replacement can is needed. The formulation is not intended for flushing refrigerant lines or for use on energised electrical components.

Questions about this item

How do I apply the Nu-Calgon 4371-75 coil cleaner to an evaporator coil without damaging the fins?

Shake the 19 oz aerosol can well, spray the foam evenly across the coil surface from 6–8 inches away, let it penetrate for 5–10 minutes, then rinse thoroughly with low-pressure water; the step most people skip is the final rinse, which leaves residue that can restrict airflow.

Will I need to replace any parts after using this cleaner on my RV's AC system?

The cleaner itself is a single-use 19 oz aerosol; no replacement parts are required for the product, but inspect coil fins and drain pans afterward — bent fins or cracked pans should be repaired before recharging the system.

What is the first limitation I will hit if I use this aerosol continuously on multiple units?

The 19 oz can empties after one or two large coils, so the practical limit is product volume; also, the propellant pressure drops as the can cools during extended spraying, reducing foam reach until the can warms up again.
