Frost King ACF19 Air Conditioner Coil Foaming Cleaner, 19 oz

I would highly recommend this product but buy two cans because one wasn't enough to do a mid sized unit. I would also recommend you look to see that whatever product you buy from Walmart.com for pick up is at the store nearest you prior to clicking the 'pay now' button! I didn't like that I had to drive so far to pick it up at a Walmart not at all close to me, but that isn't the products fault.

I pick up this coil cleaner whenever it goes on sale, as I tend to use it on my systems at least once per year. The scent is pleasant, and it does a great job of cleaning (even though the foaming cleaner itself can be a little messy). I like to use an "approved" product like this because it makes me feel better to know that I am not damaging my coils with any other type of serious cleaner that might do a good job initially, but damage things in the long run. At full price I would not say it's the best value, but if you keep an eye out like I do, you can pick it up very affordably. Shipping or delivery makes that process a breeze.

Search this product anywhere online as well as You Tube and it is %231 rated to use by actual certified HVAC technicians. The other factor that affected our decision to purchase was Walmart's AMAZING DEAL on it!!!

I used this in my condo a/c unit. We have hotel/motel type units. The previous owners never cleaned the unit nor anything else in the condo but I digress. It took using two cans to break through all the gunk but it did clean the condenser coils nicely and no bad smell.

With finances being tough right now, I decided to try to clean my coils on the outside ac unit. This stuff was amazing and very easy to use. I only used one can because I was unsure how it was going to work. Will probably clean it again at the end of summer.

I ordered this product because I watched the YouTube video on how to clean a window AC unit. the man in the video recommended this cleaner and I recommend it also. it does a really good job for quick cleaning and even better job if you can take the AC unit apart and do a deep clean. works very well either way.

Ok this stuff is a process , but worked amazing ! Our AC wall unit was not blowing cool aor , gave this stuff a try and it REALLY helped ! We were shocked at the amount of "gunk" in the unit , Highly recommend and Walmart has the best pricing on the Frost King Cleaner

So it's been hot out here in SoCal and our old place doesn't have any AC so my wife and I have been melting until a buddy of mine gave us an old window AC unit. The unit itself works good however it had a musty smell even after hosing it off. I sprayed the cleaner as directed and let it break down on its own and presto the AC unit has no musty smell and smells fresh.

Pro: It works. It foams and pushes out debris, dust and grime to a significant degree.. Con: The foam forms immediately upon exiting the can, so sometimes you cannot get it i between the fins before it starts blooming. Sometimes the foam spritzed in all directions, so you have to wear protective eye gear. The scent isn't necessarily bad itself but a chemical scent has remained after the cleaning and even after several days of using the machine, it continues.

I did not get Frost King product, instead was send a generic coil cleaner, very disappointed. And it came from Home Depot not Walmart. Will not be doing this again. I would give 0 stars if I could
