Arm & Hammer Biodegradable HVAC and Air Conditioner Coil Cleaner Foam Aerosol Spray, 19 fl. oz, AHCC-19 by Diversitech

Works well, nice smell !

Excellent coil cleaner. Worked very well. Easy to apply and rinses off cleanly.

Really works I use in my AC and all the smells disappear. High recommend

It definitely did what was expected used almost a whole can for a very dirty mini split. Used it on the inside part made a huge difference.. Would certainly buy again.

Worked great - got soooo much out. It's easy and it's strangely satisfying to spray on and watch it pull stuff out. The window A/C unit runs better and no longer occasionally shoots out little bits of dust and things that got past the filters. I did multiple rounds (plus spray bottle with very warm water between rounds) and there is still some left for a future cleaning. The smell is also nice - a fresh orange scent that isn't overwhelming and isn't 'chemical-y'

works as described

Also great for cleaning and deodorizing a vehicles AC evaporator. I use this every time before I replace the air filters on my Tesla Model 3. It effectively removes any odors the AC system may be producing and cleans any dirt off the evaporator. This product also foams up a lot which ensures my entire evaporator is coated in the cleaning solution. After about 10-15 minutes the foam dissipates and drains out of the AC drain underneath the car. Although rinsing is not needed, I usually spray water onto the evaporator afterwards to rinse it off. Then I wait overnight and then drop in the new filters. With 19oz vs a 6oz Kool-It bottle, at the same price, this is the evaporator cleaner to buy!

It worked well for us while we cleaned our hvac
