Great stuff and it works good. No doubt it will pay for itself in increased efficiency

Worked okay. Was very hard to spray in the coil at the angle I had access to, and halfway through the bottle it was out of propellant. Didn't do a fantastic job of cleaning the coils but did get some scum out. Probably fine for your window unit though.Bought two of them to compare and wasn't super impressed with either of them, honestly. I've had a few A/C guys recommend a vinegar/water solution, followed by rinsing with a spray bottle of water, and some gentle toothbrushing. I'll probably do that next time, as one can of this could get me enough vinegar to last a few years.

This is the PERFECT cleaner spray that you can buy. It works as it should. Foams better than others. I have a little tip here; if possible rinse off cool with a spray bottle with water. Brush off heavy amounts with a brush.( don't bend the fins) I applied and turned on my mini split so it would get sucked in and clean the fan also. I used a pump spray bottle to really clean it. Again USE AS DIRECTED this is how I used it on my mini split which is not recommended. As u can see in my photos as this was my first time I recommend covering entire using with painters tape. Then Duct tape only over the painters tape to repel the water. I slit one side of a large garbage bag and used it as a funnel, I then taped that to the unit under neath. I then slit a hole in bottom of the bag and placed a 5 gallon bucket to collect the run off. I used a insect pump sprayer and filled with tap water. I cleaned the coil.the fan, the drain system(very important & the lower vents. Total cost to clean one of my HUGE split units was under $20. again. Do this with your own regard. The painted wall was primed so I made a mess the first time. I know what to do now.

I tried this spray-on foaming cleanser on my outside A/C unit (condenser). The unit hadn't been cleaned in 4-5 years, but isn't exposed to leaf-blowers, splashing dirt, or high winds. It's in heavy use only 3 months a year (and light use 2 additional months).The cleaner seems to work as advertised, loosening dirt build-up, which I then rinsed off with a hose (rinsing until there's no foaming on the unit). The water coming off wasn't visibly dirty, but when I was done, the outer fins of the condenser definitely looked cleaner. One thorough application seemed like enough, there was no need to to repeat the process.Note that one can isn't nearly enough for a mid-sized residential unit, doing the 3.75 sides of my unit that allow air-intake took 3-4 cans, so be sure to order enough. One can covered just a little more than one side of my unit. But even the cost of 4 cans is a lot less than hiring an HVAC company to do a cleaning. Recommended.

Worked like gangbusters. I had a couple window units that I grabbed from my moms garage when my central air unit took a crap. They weren't very productive so I went online to see how I could fix that. I found an article that recommended this coil cleaner. I bought a few bottles from amazon and used them to clean both window units and my outdoor central air unit. The grime that came out of those coils was disgusting. But better out than in. The window units were much better after the cleaning. Just make sure you have something to catch the excess drippings if you're cleaning these while they are still in the window. I had a bit of a mess on my hands because I didn't account for the extra moisture that the coil cleaner adds.

I bought this to use on the inside coil for my homes A/C unit. I unscrewed the cover to the coil compartment and was surprised to find a dead bird inside. Seriously, how the heck did it get in there? It was dry and weighed next to nothing. After removing the bird carcass I sprayed a liberal layer of the foaming cleaner to both sides of the coil and waited for it to percolate through. I then sprayed another layer and replaced the cover. I turned on the A/C unit and lowered the temperature on the thermostat so it would condense some water. My furnace has a clear trap so you can see the color of the water that drips through it. After a while the water was cloudy brown. I used the brush to clean out the tube and left it. A few days later I checked it again and the water is clear so it appears that this stuff released a bunch of dirt and gunk that rinsed off.

After being through a few cans of this and reading other reviews, I wanted to post my own thoughts.First off, I used this on my indoor evaporator coil. I bought this house about 3 months and the AC is about 7 years old. The product is basically like a really foamy windex and it shoots about 5 inches from the can so you really have to get it up there for "A" units.The setup that worked for me was to put a couple towels under my coils ("A" shape configuration) so that the dripping could come down onto it and not all over my floor. I coated the coil thoroughly and noticed a ton of grime coming off into the solution. I ended up coating it again and then using a toothbrush to really scrape the coil and get a lot of the gunk off. After a second coating I was ready to rinse with water in a water spray bottle.The coil looks a lot cleaner now and I think that the air will flow through much better. Great product, but for me you definitely need to rinse and use some elbow grease on a dirty unit.

Product works great. Foams up like crazy and smells like super concentrated window cleaner. I used it on my roof top camper A/C with the unit off the trailer on the evaporator and condenser coils. Folks say you do not have to rinse it off, but I couldn't imagine it not getting rinsed, especially on the evaporator coil (interior cooling coil). Still, it's a great coil cleaner - would definitely buy and use again...
