Rated 5.0 out of 5.0 by Great A/C coil cleaner I cleaned my a/c coils just by spraying them and the product does the rest. My central home a/c is working fantastic in this hot Florida climate! July 1, 2014
Rated 5.0 out of 5.0 by Works great If you're trying to clean your a/c yourself, you'll probably come across youtube videos telling you to spray your coils with dish detergent. This might be a good idea for a first rinse, but it won't really clean your unit out. I immediately saw 5+ years of dirt and grime oozing out with the foam using this can of stuff. The scrub brush is useful to complete the job without messing up the fins. This also turned my brown filter white and clear. Left my space with a nice orange scent for a few days after starting up my a/c again too. Well worth the five bucks. March 11, 2015
Rated 5.0 out of 5.0 by Great product! Saved me $88 + cost to clean the coils My condenser fins and coils were dripping straight to the AC filter then the floor instead of the water sliding to the sides to get collected and sent down the drain line. From what I read, this could be either due to dirty fins or due to the unit being low on freon. I called the AC company and they quoted me $88 just to come and inspect it. To fix it it would have been extra! My fins looked fairly clean so I was leaning more towards the second possibility of the freon being low. I figured, for $5, I won't be losing much and I will have clean coils even if that wasn't the cause. I bought one of the cans and it had a nice brush that I used first to loosen the dirt. I then used a shop vac to suck the lose dirt, then I sprayed the foam. It did not cause a huge mess as I expected and I wore eye protection. It irritated my breathing a little. I left it for 10 minutes then I wiped it down and ran the AC! Not a single drop of water. All the water is now going down the drain line as it is supposed to. Now, when I shine a light, I can see the coils through the fins which were not visible before. Overall great product. It saved me at least $88 plus the price of labor to to clean the coils. Highly recommend. June 11, 2014
Rated 5.0 out of 5.0 by Great product with many other uses! Very easy to order this product online with the free shipping option. I have used this foam cleaner to clean out engine bays in my ATV and snowmobile. Product is not harmful to plastic, rubber and other sensitive materials. I always buy a box full at a time!

Rated 5.0 out of 5.0 by THIS STUFF WORKS The Central Air unit in my attic was blowing foul-smelling air ; somewhere between vomit and old vinyl. The a/c company suggested to look inside the air handler in the attic. Possibly a dead mouse was responsible for the smell. I found no bodies. I researched online and saw reviews of this and other coil cleaning products. I decided a $5 investment wouldn't be so bad if it didn't work. Even though the drip pan was dry and had some dusty residue and the coiI itself looked clean I decided to clean the coil. I used an entire can and let the foam evaporate as the instructions said it was self-rinsing. I reassembled the unit and turned the thermostat to make the unit come on. A lemony scent came through at first and then dissipated as the unit operated. Voila! it worked. No more foul odor! June 22, 2014
Rated 5.0 out of 5.0 by Worked on the compressor coils well! I sprayed this onto the compressor coils, waited until the foam subsided and then rinsed them well with the hose. A surprising amount of dirt was released. Prior to this product, I always cleaned the coils at least three times during AC season with just the hose, but this product increased the cleaning power tremendously and left them silvery-shiny! I bought two bottles of this and am glad that I did! July 23, 2013
Rated 5.0 out of 5.0 by Excellent Product I was told I needed a new hvac unit during a service call due to frozen coils. Did YouTube search and found out it could be caused by dirty coils. They were filthy. We vacuumed/peeled off what we could then used this product. We did two applications. The results were immediate and the hvac system works better than it ever has. Super easy to use, clean scent, fumes weren't an issue that I can recall. Saved me over $3k. August 12, 2014
Rated 5.0 out of 5.0 by Foam Coil Cleaner - EXCELLENT Product! I thought I'd try this stuff on a wall unit in my den. The coils/fins had never been previously cleaned so, upon inspection, the build-up of crud led me to think, "No way is this going to get clean." But, I had to try. Spraying horizontally, starting at the bottom, the Foam Coil Cleaner forcefully shot a thick foaming mass into/on to the fins. It continues to expand as you spray! In no time, the entire coil area was covered. This product delivers EXACTLY what it promises! In about 20 minutes the foam was gone, having done it's job, and the product had completely rinsed itself away. Due to my neglect, a 2nd application was required. (I'm not sure as to the toxicity of the fumes produced, but the scent is powerful so it is a good idea to keep the area well ventilated during use of the product.) Finally, as usual, Home Depot provided great order processing and shipping service. Well, don't just sit there... BUY THIS STUFF! June 9, 2009
