impressed

I was skeptical about this working lol but let me tell you! the nasty smell coming from my Window AC is gone! Now I did spray the foam and use the little scrub lid 3x just because of how dirty my window AC was! but the results are impressive!

Easy to use, a great results.

Our 4year old portable air conditioner had a horrible smell when on, I drained it but still had that bad smell. I actually started looking around for a dead mouse. When I determined there was no mouse, I did some research. I watched videos and read HVAC blogs, when I was satisfied the coils need cleaned, I found this product at Walmart. Came home from work poured myself a glass of wine, got my thesaurus so I had a variety of swear words at hand then took the unit to the front porch. I instantly found out I could not remove the vented casing to get to the coils as the video showed, (Glad I had that thesaurus) so I shook the can and sprayed into the vent that covered the coils and hoped for the best. I let it sit for about a half hour, then plugged it in and I'm thrilled to report the smell is gone. It has been replaced with a nice citrus fragrance. I thought I was going to have to replace the whole unit, but this can of coil cleaner saved me hundreds of dollars. I do recommend it.

Good Value. Works As Expected.

No chemical smell, fast and effective. What more could you ask for? It's also priced right. Most importantly, however, is the pressure was enough to force the foam into the fins for deep cleaning, but not so forceful as to cause too much overspray everywhere. Three-quarters of a can did a small 8000-btu unit, so a single can should do a room-size 1000-btu unit just fine.
