As a first-time AC cleaner, I was nervous tackling my filthy unit surrounded by trees. The Coil Cannon made it shockingly easy – just pour, dial, and spray. In 30 minutes, my AC looked brand new!

The automatic mixing is genius. No more guessing ratios or messy manual mixing. I used setting B with Nu-Brite cleaner (pro tip from another reviewer) and the foam action was perfect for breaking down years of grime.

That 2-quart capacity is a game-changer. Cleaned both my 3-ton condensers without constant refills. The large mouth prevented spills when pouring concentrated cleaner – a small but crucial design detail.

Bonus: The interchangeable spray tips are brilliant. Used the wide one for general cleaning and swapped to the narrow tip for tight spaces. Though fair warning – the siphon tube installation isn't intuitive (had to YouTube it).

Saved myself $900 versus professional cleaning. The satisfaction of watching years of dirt wash away? Priceless. This Texas summer doesn't stand a chance now.
