HVAC Guys Coil Cannon | AC Coil Cleaner Automatic Foaming Mixing Sprayer | Compatible with All Cleaners & Chemicals | 5 Dilution Ratios

Works great --- sprays a nice smooth and consistent coil cleaning foam across a wide pattern (used simple green foaming coil cleaner). Make sure to tighten up the fasteners before using and push the quick lock all the way in until you visibly see it lock in.

I used the VAC Guys Coil Cannon AC Coil Cleaner Automatic Foaming Mixing Sprayer together with Simple Green Foaming Coil Cleaner, and the results were excellent.This is not a quick maintenance job. It took some time to remove the fan and motor assembly, take off the four side panels, vacuum out leaves and debris, and then thoroughly spray both the internal and external coils. However, the process was straightforward and the equipment worked as expected.Pros:Very effective cleaningFoam application makes it easy to cover coils evenlyNoticeable improvement after cleaningCons:Time-consuming processRequires partial disassembly of the unitOverall, the effort was well worth it. Having clean coils before the summer heat kicks in gives peace of mind and should help with system efficiency.

Very good craftsmanship. Cleaned many units with this unit. Foaming is a plus. Size is not to big and not to small.

Works well and easy to use.

This is a great alternative to NuCalgon’s overpriced kit. Works just as well and the only downside is the hose attachment comes off pretty easily but it reattaches easily as well. Works great, doesn’t leak.

Easy set up and easy to use. Made cleaning outside hvac unit a breeze

Used to clean AC coils. Works awesome and has adjustability of how much cleaner vs water it uses.

Easy to use and foamed pretty well. Nice that it has the dilution dial on top. I would recommend.
