Made with special surfactants and alkaline cleaner, Evap Foam is ideal for use on most coils, but particularly suited for use on cooling or evaporator coils. Simply spray Evap Foam on the coil and the condensate produced during cooling will wash the emulsified matter off the coil.

Used in on my ductless mini-split A/C units
If you have one of the ductless mini-split air conditioners, SOMEONE is going to have to do maintenance on it, or it will become useless. Maybe someday they'll be re-designed to be lower maintenance, but till then, if you don't keep the coils clean, the 'drain pan' (which is quite small & narrow) clean, and the drain line open, you're going to have water intrusion & big trouble. My two Klimaire units didn't have any issue until the second year of svs. I live in the middle of Tx, maybe not the hottest place on earth, but our summer months are plenty hot. I had several A/C techs out when one of the units began leaking water down the inside wall, & they were clueless as to what the problem was. Long story short, coils & drain pan needed cleaning, which is where this Evap Foam spray on cleaner, comes in. Someone is going to have to partially disassemble your mini-split to clean the drain pan, & clean the coils. After a lot of money spent on ignorant a/c techs, I began doing this task. This Nu-Cal is the only brand I've tried so far, & I don't think there are a lot of equivalents at this point, & I've got a couple of cans ready to go for the next time I need them. Ductless systems 'can' be great, but either you, or someone is going to have to properly maintain them, and if it's not you, you best know a professional that is familiar with how to keep them properly serviced.

If your evaporator coils are dirty, this WON'T clean them - guaranteed.
I tried this on my evaporator coils, at my residence. I have a Carrier furnace/AC unit located inside my house. It's about 20 years old. My AC wasn't cooling as well, so I decided to check out the evaporator coils, because I never even looked at them in 20 years. After figuring out how to take the cover off the A frame, I found the evaporator caked with "crud". I guess my air filter hasn't been doing a very good job, because the evaporator coils aren't supposed to get dirty. I would say they were very dirty and caked with dust and hair, mainly. After scraping off the surface layers of "Crud", I then tried the Nu-Calgon foam. It's supposed to be squirted between the fins as a liquid and expand, which is supposed to push the "Crud" in the fins to the outer surface, so it can be removed. I applied the Nu-Calgon as directed and waited the appropriate amount of time, for the cleaner to do its thing. I did notice a little black filth mixed in with the foam as it liquified. I then used a Diversified T101 fin comb between the fins and pulled out all kinds of deeply impacted "crud". The fin comb did a much better job of getting the "crud" out, than the Nu-Calgon. I would say the Nu-Calgon removed almost nothing and isn't worth the $14 price tag. It may work if your coils aren't very dirty, but if they are dirty, don't waste your money on this stuff. I don't have the ability to remove the evaporator coils and take them to a car wash (the best way) so I used the the fin comb - My AC started cooling a lot better, after the fin comb. Compressed air did little to clean the impacted coils. In summary, I felt like this product was a waste of money, because it didn't work well. I could have used 10 cans of this ($140), and it still wouldn't have removed as much "crud" as the fin comb ($8). Read full review

Great product and super easy to use.
This is a great product. It could not be any easier to use. Just spray it on your coil and walk away ! It cleaned my coil very well and I did not have to rinse the product off. It also gave my coil a clean fresh smell ! I would highly recommend this product to anybody ! I will use it again !

Great stuff!
Did an awesome job on my AC coils in my garage unit that haven't been cleaned in 12 years! I consider myself some what handy but the Calgon coil cleaner honestly couldn't be any easier to use! Amazing stuff and good to know my kids and I aren't breathing in all that moldy build up anymore! :)
