Nu-Calgon417175 Evap Foam

Works great, used on evaporator and condenser. Thorough wash on condenser, just spray on evaporator. Doesn't smell like a harsh chemical, left the house smelling clean and fresh.

Fast delivery, works exactly as stated. A must spray cleaner for your RV/home AC. Easy to use, and not as messy as you would think. Would buy from this dealer again.

Does what is says quickly and efficiently. Smells great and neutralizes abject odors. Price knocks it off a star as there are better products out of Europe that work a bit better yet slow boat shipping makes them less desirable. Primary Ingredients are not as expensive as the manufacturer specs to the consumer. Easy to use yet value for money is lacking.

Why did you pick this product vs others?:It worked! My ac would freeze the instant we turned it on. The coils had never been cleaned inside so I said a prayer and clicked order. It foamed fine, showed signs of instantly working. You could literally see grime in the foam. It also helped clean my drain line that was super slow! Added bonus :) First night it was still freezing but not as bad. Left if off overnight and then next morning it did same thing. Figured low coolant. I turned on for little bit so house wasn’t above 90. That second time it quit freezing. There must have been a piece of debris stuck that finally let loose after cleaning them! This saved me the $150 for topping off coolant! Thank you!!!There’s still a bit that’s visible from how dirty this was but I didn’t have the comb or anything and ac is working again so im beyond happy

I'm really impressed with this item! From the moment I unboxed it, I could tell it was well-made and designed with the user in mind. Setup was straightforward and quick, which is always a huge plus.In terms of performance, it has consistently exceeded my expectations. It does exactly what it's supposed to do, and it does it reliably and efficiently. I've been using it regularly for a while now, and it still feels as good as new.What I particularly appreciate is its ease of use. The features are intuitive, and I didn't need to consult a manual to figure things out. It truly makes my life easier.Overall, this has been an excellent purchase, and I genuinely feel it offers great value for the price. If you're looking for a dependable and high-quality item that delivers on its promises, you won't be disappointed with this one.

Easy to use and does the job. No harsh chemical smell and I could see it working as soon as I sprayed the coils. I will be buying this again and adding it to my normal household maintenance routine.

It works well, but if you use about four cans a month to remove all the stuff stuck in the evaporator...

Used this no-rinse foaming cleaner to clean the coils on my wall-mounted Split AC unit (Mitsubishi). Wow. Worked really well... bubbled dust and grit to the surface and slowly dripped the accumulated gunk down to the drain pan so I could towel it up and toss the mess. After about 30 minutes, the coils were actually shiny silver again. I will be ordering another can when I clean the units again in a year or so.
