Careful, idk about this one but some of these cleaners are corrosive and can do more damage than good.

This one is quite reputable. I missed the other sale so this is perfect for spring prepping for the summer heat.

Highly recommended. I use this twice a year on my RV ACs with excellent results. If I hadn't stocked up last deal I'd jump on this.

So not doubting this to be true, but I had inherited a 2/3 year old Hisense unit from my home's previous owners. Was in great shape. I'm obsessed with moldy ACs and always clean them really well. I did my usual trick of degreaser to clean and bleach water to sanitize. Not only did the bleach start to corrode some of the fins but I think I got degreaser in the motor bearings and the fan ran like s***. Had to throw it away. On my new units I used this spray. Not only is it easy to use, it's lemony fresh and did a much better job at cleaning. It also kills organisms without using bleach which is very harmful to the cheap thin metal that all AC units use for the fins.

Why on earth would you use bleach on an AC unit?!

It wasn't straight bleach, it was diluted, and it was to kill mold. But its also corrosive to metal. i never had an issue before but I also was cleaning older, likely better built units that didn't seem to mind.

It isn't so much being "reputable" but use case. Most of the corrosive coil cleaners are contractor grade, meant to be used exclusively on condensing units / coils / cooling towers (never on evaporator coils), require dilution, and heavy rising. They can be very hazardous in the hands of those who claim to 'know enough to be dangerous' (and generally are...but not in a good way).

This on the other hand is more of a foaming detergent / deodorizer vs a rather caustic 'cleaner' you likely find at an HVAC wholesaler.
