This is a great product.

Producto de maravilla

Had a musty smelling evap coil that i needed to clean…..this stuff worked and did the job. If i was going to do this task more than just once, i’d go ahead and buy the liquid and a hand sprayer as its was more bang for the buck—this stuff is really expensive.

Product was received broken in box with no wrapping other then a single piece of unsecured bubble wrap. Cap was not taped to can either. I attempted to apply what foam I could get out with a mushroom brush to avoid damaging coils. Not sure if it is worth ordering The company contacted me and made this right. They refunded me and I ordered a new can. All I can say is this is absolutely worth it. I work in a resort and asked an engineer for a recommended brand of hvac cleaner. They said viper. It’s what’s used in the resort. I sprayed this on my unit and the crap that dropped out was GROSS. I did use a mushroom brush to gently dislodge the gunk. Mushroom brush is in the trash and the intake unit looks so much better then when I moved in a few weeks ago. The sprayer is very important since it gets between the fins.

I was a bit sceptical using this stuff. There is a lot of snake oil HVAC things on the market. But, this stuff actually works. I am not sure if I used too much but I ran out before getting all the way around the coil. If you have a medium size or larger condenser I would recommend getting 2 cans to be safe. Also, I recommend removing the fan from the top so you can flush from inside the coil. Obviously remove power before doing this. I am happy with the results and will purchase again.

Lots of product in the can. I rinsed the unit before using because of excess pollen and other material. I was able to spray the condenser very thoroughly and let it sit until the foam dissipated. Afterward, I thoroughly rinsed the coils. I was very happy with the end product.
