Frost King ACF19 Foam Coil Cleaner, 1.18 Pound (Pack of 1), 19 Ounce

My window A/C and Heater unit would only cool down to 60 F. After foaming cleaner was applied the unit is now cooling down to 48 F. Great product!!! Easy to use as well.

I heard about this foam coil cleaner on social media and realized I had never cleaned our air conditioner. Turns out, it was disgustingly dirty, but this product worked like a charm! The foam expanded, lifted all the grime, and left the coils looking (and working) so much better. I noticed an improvement in airflow almost immediately. I’ll definitely be making this part of our yearly maintenance from now on. Great product that actually delivers!

Had an old window A/C unit that was taken care of very well. Instead of a new A/C one I figured I give it a try to clean the old one. I left the unit in place in the window ( I'm 70 ) and did not want to try to remove the heavy old one. It took only a few minutes to spray on and I did it twice to insure the coils were clean. Now the unit runs almost as good when it was new. Worth it to try before you spend a ton of money on a new one when your old one was just dirty.

Have a room a/c that needed to be cleaned. This product worked great. Loved having the scrubber on top. Did not end up using it all the first time so put it up for use again when needed. Was pleased with the outcome. Would recommend.

Worked very well for outside air condenser coils. I sprayed directly through the grates onto the coils and let it soak then rinsed with hose. They look brand new.

It cleans so well, this stuff is great. Foams huge, lots of foam. Huge surface area coverage. Restored my refrigerator and air conditioner. I love this stuff. It's so much better than Simple Green. It's so easy to use, just spray and scrub.

Works great, but keep in mind one can will be lucky to do both sides of a condenser that is 3 tons or less. My 5 ton outdoor unit needed a full can for the inside of the coil, and a full can for the outside for 100% coverage.

Was disappointed in how small the stream was out of the sprayer. I paid extra for the brand because it sounded like the spray would be easier to cover the complete coils. Next time I will go with a less expensive brand.
