Air Conditioner Foaming Coil Cleaner

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

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!

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.

Worked as described.

Used this today on my Amana 5 ton 2 stage unit today and it looks new. It is 12 years old. I have cleaned it most every year since I installed it 12 years ago with water Only. I'm not a professional HVAC guy or anything, I bought this monster along with a 2 stage furnace on eBay and installed them both (I did have a couple guys come out and connect the line set but outside of that I did it all including the plumbing pipes as well as enlarging the return air system at the furnace). The guys that did the line set said I did a better job than a guy that has installed for them for 25 years! Anyway, I sprayed the cleaner on the outside of the coil and let it sit for about 10 to 15 minutes. I had already removed the fan from the top of the unit and vacuumed out the inside. I hosed the coil out from the inside out. The fan sucks the air through the coil from the outside to the inside so this is the way I was taught to do it many years ago (to me it only makes total sense). To spray it from the outside-in is only packing the dirt back into the coil. I Did spray the outside off After spraying from the inside out in order to remove the detergent from the spray foam. This product gave me much better results than I have gotten in years past with water alone (using this exact same technique). I must state, I did Not read the instructions. I can only say this method worked great for me!

My RV evaportor coild was completly clogged by buildup. Sprayed it on, left it for about 10 minutes and then used the brush built intp tje lid. I jad to repeat it a couple of times becauae the buildip was so extreme (see pic), but in leas rhan 30 minutes it was as good as new. Another plus is that it has a pleasant scent (lemon).

Easy to use and really good cleaner ,

WORKS GREAT! Central AC inside unit evaporator coil assembly was leaking. Sprayed coil cleaner on the air intake fins, let sit for one hour and spray rinsed with pressure spray hose. This cleared out the years of accumulated crude. LEAK STOPPED AND AIR FLOW INCREASED! Note: Before spraying with hose, placed on floor 2'x3' rectangular black plastic tub used for mixing concrete, sold at Home Depot... to catch water and debris.

I don't know if this is the best coil cleaner, but it is effective, and a good value! I cleaned all 4 faces of the attic coils of my 30 year old central A/C twice, (brushed, foamed, waited 10 min., rinsed with hot water), and the inside coils of a 5 year old window A/C unit twice, and the outside coils of the window unit twice - all on 1 can of A/C Safe Coil Cleaner! And all of these cleanings were complete foam-outs, with every surface covered with thick foam, no gaps. I was impressed with the coverage (be sure to shake can often)! I was also impressed with the results - the air was blowing much stronger and cooler (6 degrees cooler) on the central air system, and a little cooler (3 degrees cooler) on the window unit afterward. I bought three cans, but only needed one (I cleaned the outdoor coils twice with remnants of an old can of WEB brand cleaner - which also worked well). I'll gladly use the remaining two cans as needed, and I won't wait so long between cleanings. Highly recommended product!
