“I bought this for my AC unit and was amazed at the immediate difference. Black debris came off that I didn't even know was there! I bought another can to keep it handy for regular cleanings. It's really easy to use and offers a great value.”

“After using this foam, my entire AC unit was cleaned thoroughly! I'm so glad I decided to purchase it. It works wonders on both evaporators and condensers.”

“This product worked well for my kegerator coils. So far, everything is functioning perfectly. I’m very satisfied with how it performed!”

“I used this product to clean my air conditioner that hadn't been maintained in years. The directions were clear and easy to follow, making the process simple and the results excellent. I will definitely purchase this again.”

“This cleaner worked wonders on my small window unit! I had a musty smell for a long time, and after using this product, it’s completely gone! I'm so grateful I found it! I highly recommend it!”

“I found this foam cleaner to be impressive. It penetrates deep into the fins, providing a much more thorough cleaning of the coils compared to other products. It left my evaporator shiny by self-rinsing with normal condensation. A solid 10/10 recommendation!”

"I found this product to be essential for cleaning my air conditioner. The nice, stiff bristles provided a perfect fit for getting into tight spots, making it incredibly effective. I appreciate the great value for the money."

"As a first-time user, I was pleasantly surprised by how well these tools worked. They performed as expected and seemed to be a reasonable price for the quality offered."

"For years, I watched technicians clean coils in my business, and now I finally used the right brushes myself. This set is amazing! The fins on my cooler are straight, and my ice machine works so much more efficiently, saving me on electricity bills. A fantastic and easy-to-use product!"

"This works great for my 5-inch long cat hair."

"I find it simple to use and well-made. After using it a few times, I’m really pleased. However, I wish the handle were a bit longer because it’s tricky to reach deep into the HVAC coils with my big hands. Overall, it’s a fantastic product that can prevent early HVAC issues!"

"This package is very useful for cleaning my A/C."

"I was surprised by the size; it’s only about 3 inches wide and 4 inches long, which makes it almost worthless for my needs!"

"I couldn’t reach the top of the fins, but I still managed to clean 98% of it relatively easily."

“I found the AC Safe Air Conditioner & Coil Cleaner to be the unsung hero against summer heat. Using it felt like giving my AC a luxurious bubble bath, and the results were amazing! The improved airflow made a noticeable difference, and I could finally enjoy those hot nights without tossing and turning. What’s more, it was surprisingly fun to use!”

“I really appreciated how easy it was to use. I shook the can, and while the spray wasn’t perfect, it still got the job done on my 2.5 ton unit. The pleasant smell during application was a nice touch, and I liked that it cleaned well without needing to scrub.”

“After trying other products, I was thrilled to find this one. The moldy smell in my AC was completely gone, replaced by a refreshing lemon scent. I used a nozzle from another cleaner for my air vents, and I’m glad I did! It’s a great, affordable alternative, especially since the ingredients seem non-toxic.”

"I love the excellent build quality of this product!"

"The customer support is truly outstanding; they helped me with all my queries."

"Using this product is so easy, even for beginners!"

"I found these tools to be invaluable for keeping my wall unit air conditioner and heat pumps clean. The stiff brush effectively removes dust from nooks and crannies, and the wire comb is perfect for straightening any bent fins. They're incredibly functional and easy to use!"

"Using these tools was a breeze! They provided great value and made cleaning my air conditioner much simpler. The quality of the construction really shows, and the wire thickness is just right for getting into tight spaces."

"I really appreciated how useful the nylon brush was for cleaning my baseboard radiators. I could easily reach the back of the aluminum fins, and it worked perfectly alongside my vacuum. However, I had some trouble with the metal comb; a few tines came loose, but I managed to fix it with super glue. Overall, they did the job I needed!"

"This brush does exactly what I need; it's easy to use and gets the job done!"

"I needed a tool to clean between the fins of my baseboard heating, and this brush has long, sturdy bristles that easily remove dust."

"I was initially skeptical due to its low price, but using the brush made me a believer. It's a great product! Just be cautious with the metal brush, as it might be too strong for my machine."

"I spent so much time cleaning my AC before receiving this set, and I was amazed at how much more dirt and debris I could remove with just a few of these tools! While I didn't find the plastic fin straighteners helpful, the flip-out tool on the blue brush and the metal tined tool really helped me get my AC looking almost new again. These tools are very helpful little instruments!"

"Each fin tool serves its purpose, but some can be challenging to use. This set offers all the standard fin tools in one package. I might not use every single one, but it's an affordable single purchase that includes them all."

"I was skeptical at first, but after purchasing my old house, I realized how much I needed these tools. The 34-year-old air conditioner had many issues, especially the dirty and bent fins. Once I figured out how to use them, they made a significant difference! While I still need to replace the condenser, at least it no longer runs constantly, and I can actually feel cool air. Yea!"

"When I tried to use this for the first time, it literally fell apart! The opposite side with the metal combs is unusable. We managed with the black brush side and a separate metal fin comb. The design is poor, and the tiny plastic nubs that hold the brush together are inadequate. I suggest saving your money and just getting a dog brush or a cheap metal fin comb instead of this set!"

"I used the Evaporator Coil Cleaning brush and Fin Comb on the same day I received it! It made cleaning the coils much easier, and I feel like I did a better job compared to using a sponge or rag. I consider it a great value at just over $10!"
