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

Have used this device several times now. Have used everything from Simple Green to actual coil cleaner. Foams each up with no problem, easy on and off to rinse. Easy to adjust mix concentrations and really handy for cleaning solar panels with mild cleaners!

Works amazingly ! I was a little worried to try a new brand but I love this !

perfect pressure and foaming action

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.

Great value

I have used the foam cans to clean my evaporator coils but this is waaay easier to use. Yes, one has to maneuver the attached hose around but it isn't inconvenient. In all, I think this did a superior job to the cans of foam. Couple of tips: -the unit came with a quick adapter inserted into the cannon and another adapter in the box. The adapter installed in the cannon was the wrong one. I had to switch the two. Very odd that it would come mis-installed from the factory -the cannon comes with two tips. The bigger one gives the broader spray and more foam. The smaller one was good for getting into tight spots. To get the smaller one on you must completely remove the larger tip first -the siphon comes in the canister and not installed. Not entirely clear how it inserts into the cannon since force didn't seem to get it to sit tight into the orifice. Turns out the orifice is spring loaded so I used a knife to pull it out then inserted the siphon. That locked in place well

The bomb for getting lots of foam. I like the detachable nozzle, no need to switch hose ends to rinse the coils.

I recommend
