It only does a good job making a mess
I bought this hoping it would clean up my outdoor center air condenser unit. I didn't expect it to be showroom new afterwards, but I did expect it to be *somewhat* clean, but alas, it did not. All this stuff managed to do was create a mess. MAKE SURE you wear gloves when using this stuff because it drips foam like crazy. Probably wasted half the bottle. Save your money on this product.

    I was able to use this product to clean both the evaporator coil and condenser coil on my window AC unit. I removed this from the window ( and power) and took off the outer metal shroud, then really soaked the coils with cleaner and used a hose to rinse the grime away. I was really surprised by the amount of grime that came out of the coils. After re-assembly, the AC unit seems to cycle on the compressor less often. I performed the flush out on my lawn with no problems for the grass and plants. I used one can for 2 deep cleanings of window units and have some product remaining. This requires a hose and water to really rinse away the debris and grime dislodged by the cleaner.

    Can't recommend this.
    This is a non-aggressive, water-based cleaner that is supposed to work without scrubbing. That is pretty much an impossibility. It is foamy, but so is a bubble bath. Just out of curiosity, I sprayed it on one of the blades of the fan in my condenser unit. It did NOTHING! I ended up cleaning it with Dawn dishwashing detergent and a sponge. The attached photo shows the "after" photo of using this AC cleaner.

      Great Stuff
      Had my doubts after reviews but tried it. Worked perfect, coils came out super clean. Dehumidifier was set to new after use. Cap was useful with exposed coil. Also did ac air handler inside with excellent results. HOWEVER, an unexposed coil is much harder to do as it’s much harder to get to. The foam stuck well and cleaned well after shooting it up into the coil. The cleaning cap was useless for this job, did use a soft rat tailed vent brush to GENTLY scrub the coils. Came out perfect, ac cooler and runs less after the cleaning. A must for ac air handlers.

        Great product!
        I just happened upon this product at Home Depot yesterday and since the instructions were so easy I thought I'd give it a try. I came home and sprayed it on and couldn't believe the amount of dirt that immediately appeared in the foam. The instructions say you don't have to rinse, but I did and feel like some extra dirt washed out with the rinsing. I'm going to post a picture and it's not sepia tone that's the actual amount of dirt that came up when I sprayed the coils. I can definitely recommend this product

          Cleaning Cap
          Cleaner does ok on inside A-frame conderser coils. Difficult to get spray to all areas because of confinded space. It would be nice if a spray tube extension was included to allow spray to all areas with can upright. Cleaning brush cap a plus but can only access upper half of coils due to lid height. I cut edges of lid for low profile as this helps clean to botton of coils where dirt and debris is worse. Overall good product. Also i used gallon sprayer ( like used for bug concentate) filled only with water to rinse coils after all cleaning and scrubbing. Not required but seems to help take everything dow the drain. Its wintertime so heat pump has no condensate inside to help so light water rinse seemed to be good

            Extremely effective!!!
            I just rented an apartment which had a strange smell. I treated the floors, got a dehumidifer- nothing changed it! Lo and behold, when I went to replace my ac filter, I discovered just how disgusting the coils behind it were, and the smell hit me with full force. I bought this product and it took 20 minutes to completely change the air in my apartment, it’s an amazing, effective, easy to use product, that I would recommend everyone buy!!! The cap was also extremely handy and easy to use. Very satisfied customer!

              Effective and versatile
              This stuff works well and is a solid value for the can. One can was enough to clean an SUV's AC condenser once and the evaporator core twice; another can was enough to clean the house HVAC condenser. I made sure to rinse the house condenser from the inside out, and there's a notable increase in airflow! A couple notes: If possible, always rinse directly rather than waiting for the condensation to rinse it away. A higher volume of water will be better at flushing out debris, especially from drains. Use a wet shop vac for best results. The nozzle can take an extension tube! While the can doesn't come with one, I dug up a long one (used for throttle body cleaning) and it was perfect to snake into the car's AC evaporator through the blower duct. The nozzle is also special to the can and is important for the foaming action. Don't lose it! I bought two cans and, after I got home, I noticed that one nozzle was missing - luckily, I had the second can. The brush cap is OK. I used a softer brush, as I felt it was a little stiff for delicate aluminum fins. Be gentle if you do use it.

                Cleaned coils AND the blower out chamber on an ac That was sitting uncovered in a shed for 5 years. The ac was filthy, mouse droppings, acorns and dust on and in the entire unit. I first shook out the unit. I then blew out the unit with a vacuum, then vacuumed out all the other crap. I then sprayed the condensation coils and the cooling coils. I completely covered the outside and what ever internal I could get to. Waited about 15 minutes and very carefully wash down the coils and parts of the ac I safely could. I then resprayed the outside of the coils again. Waited about 10 minutes and with a fine brush, brushed the coils. Washed the coils and allowed the unit to dry. I turned on the unit and ran it for 30 minutes. I checked the unit with a fine tooth comb. No smells, no sign of any dirt or whatever was on the coils. The coils looked as good as they could. Not shining as new, but close enough for what this ac looked like a few hours earlier. The product is a miracle.
