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.
Pros: Easy to Clean, Easy to Use, High Quality, Nice Design
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!
This product works great. I was able to dissolve build up on the condenser metal fins and blower wheel inside my three min-splits. This product got everything super clean. I highly recommend it. I will be using it every year now.
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.
This is a good foaming coil cleaner, likely as good as any, a good price, and easily availability at the home depot. Use it for a yearly maintenance cleaning of your evaporator coil. One can is enough to spray the coil. I have seen it reduce the pressure drop (static pressure) across a coil by .2 inch water column. To see if your coil is clean and working properly, look up the manufacturers data sheet on the evaporator coil and see what the static pressure drop is supposed to be for your application (airflow), and measure it with a manometer. It is likely between .15 and .25 inch water column. If it is higher than that after using the coil cleaner, then it needs professional cleaning.
But its not magic, this spray on foaming coil cleaner will clean a dusty coil, but if you have cat/dog hair and lint packed into the fins of the coil because someone didn't have a furnace filter installed or never changed it, then you will need a professional to clean it, and that will cost several hundred to even $800 or more if they have to evacuate the refrigerant and remove the coil from the system to clean it. Its much cheaper to have a good filter system with a 2" thick or better low pressure drop filter and occasional maintenance with a coil cleaner like this one. Be careful of the small 1" pleated high efficiency filters, meaning merv-8 and above, because they can add a pressure drop across the filter that will reduce the airflow and reduce the efficiency of your AC system.
Most, and I mean like 80%, of AC systems suffer from low air flow over the coil which reduces the efficiency of the system. The causes of the low air flow is from too small return duct sizes, not enough return air ducts, too small or too few supply ducts, dirty filter, dirty coil, incorrect setting for the blower motor fan speed, or wrong airflow because of incorrect altitude compensation. At sea level and a normal to dry humidity the equipment manufacturer likely specified 400CFM per ton of cooling, at 5000 ft elevation, it needs to be 500CFM per ton because the air is thinner. In the east with high humidity at sea level it may be 350 CFM per ton so that the coil is cooler, below the dew point, so it can condense more water off of the coil and dehumidify the air.
The one thing that you can easily control is to keep the filter and the coil clean.
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!
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!
Pros: Easy to Use, High Quality

Review 9 for Air Conditioner Coil Foaming Cleaner
Works good in combination with steam pressure or gentle spray.
I am Currently doing a coil cleaning project for my mom and her A/C coils were extremely dirty and had a sort of soot on the air handler. i took to using this spray and a gentle stream of spray bottle water, but it hasn't removed all of it. After using two bottles and vacuuming it, it has since worked better and cools better. For those of you with the same problem as me i recommend using foaming coil cleaner along with steam pressure cleaner to clean the coils for those really stubborn coils. I will soon be receiving my steam cleaner by mail to clean my coils and i can guarantee my coils will be dirt free...

Review 10 for Air Conditioner Coil Foaming Cleaner
Make sure all power is off. Circuit breaker or fuse pulled out. I sprayed the coils and it foams up well with a slight scent. Wait about 10-15 minutes and wash it off with gentle spray with the garden hose. It's that easy. Note I think you need at least two cans to use for a small-medium unit. That is how many I used for my unit. The foam is gentle and has never damaged my coil fins at all. Been doing this for two seasons already.
Pros: Easy to Use

Review 11 for Air Conditioner Coil Foaming Cleaner
I just had my AC serviced last week even though I try to maintain it clean. Freon and all other aspects of it were good. They recommended that I do a coil cleaning since the fins were pretty dirty. The service guy said they normally charge between $185 and $250 depending on time to clean. They use a foam like cleaner that gets sprayed on and then either washed off or the coil condensation would rinse away, and there was no need to remove the coil for cleaning. I decided to search for products and do it myself. I purchased this product and was astonished at the ease of using it. I used a wet vac with a soft brush end after it soaked in and allowed to clean the coils, took about half hour total time. Ran my AC afterwards and system was noticeably colder due to the clean coil. I highly recommend this product if you want to save on the AC service charging you up to $250.00 for the same thing.

Review 13 for Air Conditioner Coil Foaming Cleaner
I've used this coil cleaner last summer and again this summer. My HVAC Service Tech told me when he performed the summer service check that the condenser coils inside the unit needed cleaning. He said it would cost me $182.00. I told him that I had this AC Safe Coil Cleaner and he said he couldn't use it, that he had to use his own cleaner. I asked him if "I" could use my cleaner right then and there while he had the cover off. He said "sure". While I sprayed the cleaner he looked at the second can and read the information, shook his head up and down and told me he would close the cover after it foams a bit. He buttoned everything back up and returned to my dining room to make out the paperwork. He commented on the lemon fresh smell and didn't try to convince me that his product was better. I've also saved my daughter and sister a coil cleaning service bill by recommending this product.

Review 15 for Air Conditioner Coil Foaming Cleaner
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!

Review 16 for Air Conditioner Coil Foaming Cleaner
Holy cow.... what is this stuff... a magic potion? I live in a town house style dwelling built in 1991 in the Northeast Philadelphia suburbs. At 23 years old I still haven't had any problems or concerns with my central air-conditioning. But my neighbor with the same unit did. Turns out, it was not her unit, but the huge amount of dirt incasing the fan motor. So it got me to thinking, maybe I'd better take a look. To back up a little bit I have a vent thermometer I purchased after having AC work done on my car. So I inserted the thermometer into an air vent to obtain a reading of 60°. I googled Central air temperature a dozen different ways, but could not get a committed answer on what vent temperature from central air should be. Just that there should be 13 to 18 degree difference between vent and return. My thermometer showed exactly 18 degrees. But after my third cup of coffee I was feeling a bit ambitious. So I removed a piece duct to expose the A-coil. Surprisingly it did not look bad at all. It was not covered with a thick layer of hairy foam. But rather patchy chunks of dirt with a fair amount at the very top of the A. So after watching a few videos on A coil cleaning, I went forward. I purchased one 19 ounce can of the AC safe T 920 foaming cleaner and after first using a vacuum cleaner, went ahead and sprayed in a whole can. Note: My A coil is rather small and copper tubing runs directly in front of the opening making it difficult to get both hands inside for a good vacuum or spray. So I was clearly working with a handicap and don't believe I did a good job. I followed the label instructions exactly with the exception of, I did opt to rinse with water. To my shock my appealingly clean coil immediately began dripping long black streaks of... I don't know what. After rinsing and allowing to air dry for about an hour I was already dirty and tired. So I went to the back yard, removed the cover off my central unit and washed out the fins with a hose from the inside out.
In short, I spent an afternoon, $5.48 on this product at Home Depot to obtain a new thermometer reading of 53° at the vent! I can not believe a 7° drop in air temperature on an otherwise well working relatively clean unit. I wonder what I would have obtained had I actually done a GOOD job. In a world of inferior products and false claims it is great to know there are still those that take what they manufacture very seriously!
Thank you so much for this product! The results are astonishing!
Pros: High Quality, works very well
Cons: should have tubing nozzle for hard to reach spots.

Review 17 for Air Conditioner Coil Foaming Cleaner
I was experiencing a low freon level in my home a/c unit. I called a tech. to come and recharge/add to the system. He recommended that I clean both inside and outside coils berfore he came as it makes a difference in the heat exchange. I did as recommended on the can and had my system recharged. It works much more efficiently now and has a nice fragrance.
The product was easy to use, and even though it's a no rinse formula, I had the luxury of being able to rinse both units.
I would recommend cleaning your system annually to keep operating efficiency at its peak.
Pros: Easy to Use

Review 18 for Air Conditioner Coil Foaming Cleaner
Works great...!!! My condenser coil was extremely dirty after years of inattention, and this foam cleaner worked great. I would recommend that you spray he foam on both the outside, and then the inside of the coil, let it set for a few minutes, and then rinse the coil with a hose. I saved the expense of a HVAC service call with this product.

Review 19 for Air Conditioner Coil Foaming Cleaner
This cleaner works great. I've used it on a car A/C coil without removing it from the vehicle, a wall a/c, and on a central A/C unit. On the wall A/C, access to the coils is easy, so it's kind of overkill, but it did get the coils clean as the day the unit was pulled out of the box. On the central unit and car a/c, this cleaner's convenient application really shines. I was able to shoot it in and coat the coils through a small one inch gap in the housing, and after a few cycles of blasting the coils and running the unit, the formerly restricted airflow now blasted! The foam kind of grows after it's been shot into a coil, so it'll get into all sorts of odd spaces. The only improvement I can think of possibly making to this product is to include an extension tube on the can, like that which comes with WD-40.
