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.

Best coil cleaning product that I've found

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.

I ordered this product after watching a YouTube review how to clean AC coils. I used this and was pleasantly surprised by the result. It help dissolve the dirt from the very thin fins around the coils. This eliminate the need to scrub those fragile fins. Just use regular garden hose to wash the coils. I also bought a AC compressor cover which keeps bigger debris from getting in between the fins without blocking airflow.
