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

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 cleaning Foam application makes it easy to cover coils evenly Noticeable improvement after cleaning Cons: Time-consuming process Requires partial disassembly of the unit Overall, 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.

This is a great product. My 5-ton unit started kicking the breaker in the late afternoon. I did a number of amperage tests, but it never really spiked high. The run would be well in normal amps until, late afternoon. Then it would slowly climb. The dirt and 100*+ temps threw it over the edge. I never trusted the spray cans; I do not feel they penetrate the spine coils. The demo videos looked very positive, and using it today proved this cleaning method is excellent. Buy this and use it with confidence. I coupled this purchase with "Leak Saver HD Power AC Coil Cleaner for All Condensers & Evaporators | No Rinse Evaporator Coil Cleaner | 4:1 to 10:1 Dilution Ratio", at a 6:1 ratio. I didn't pull amps today, but I did use my fluke laser thermometer. Yesterday, the breaker popped at 140F. Tonight, during peak period and 102F outside, it was 118F.

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.

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.

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

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

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