Leak Saver Foam Blaster AC Coil Cleaner Foam Spray | HVAC Coil Cleaner for AC Unit | Professional Deep-Penetrating Formula for Evaporator (No Rinse) & Condenser (Light Rinse)

If you want to clean your window air conditioner without taking it out of the window this stuff is great. It doesn't need to be rinsed off of the evaporator coils (the ones on the inside), so you can just spray it on and then turn on the air conditioner when it's finished. It shoots a very tight spray to get in between the coils and then foams up. It has a nice citrus smell and it will take away musty odors coming from your a/c. It will also work on the condenser (outdoor) coils but it has to be rinsed off with water. Do this once or twice a year to keep your air conditioner clean and smelling fresh.

I've been using this product on my Mom's indoor HVAC unit that has been badly neglected for many years. There is literally a compacted dirt cake around the coils underneath the fins. Standard foam spray does little to help, but makes the exterior "look" clean. This spray is more heavy duty and precise. With delayed foaming action, it allows the foam to reach the deeply embedded dirt. Still, on a system that hasn't been cleaned in a severely long time, even the best products struggle. I've used all three cans, and every time more dirt flakes work themselves out of the fins. The problem is that any remaining dirt migrates over time, gets stuck again in a different area, and causes dripping of water that falls onto the filter itself. I'm planning on buying another set of this brand. My best advice for a badly fouled indoor coil is to spray from both sides of the fins, top side and bottom side, use a soft paint brush the gently brush out the dirt flakes, use a properly sized fin comb to reach into hard to reach corner spots and smooth out any damaged fins, follow with a light rinse using a spray bottle, distilled water is preferable but not absolutely necessary. If I do buy another set of cans, I will update my review and let everyone know the results. This product is so far the best one I've used, is easy to use, and probably highly effective for an average dirty HVAC coil. For a compacted dirt cake like mine, be prepared to be persistent, multiple cleanings will be necessary to break all that dirt free.

I bought the 3 pack, I saw a lot of videos, pros and cons, I pulled the trigger and bought it! it worked! all of the dirt grim came off like better, I do recommend this product! the smell is clean, not even strong scents that lingers. It foams up really thick and full. I totally recommend this product!

Cleans good only thing that would make it better is if its smell wasn't as strong. Maybe it was just that I used the entire can in a window unit. Would buy again

Very easy to use, good foaming action. My coils were not as dirty as I thought even after 10+ years of never being cleaned but the water runoff was still dark. Consider 2-3 cans for 2 row condenser and indoor evap cleaning as one can barely covered my single row condenser and indoor evap coils. Pleasant scent but consider ventilation or respirator for indoor evap cleaning. Great product, will use again for future coil cleaning.

Did a great job on cleaning the indoor coils and a fantastic job of cleaning the dusty, moldy, caked blower cages on my mini splits due to unintended neglect. It also left a pleasant lemon scent from the cleaning. I dreaded the thought of removing the blower cage to clean it but opted to leave it in place and rotate and spray repeatedly until soaked. To my utter surprise the gunk started falling off within a short amount of time. I used the Leak Saver Mini Split Cleaning Bag (recommended) and a 1 gal pump sprayer after the recommended soaking time to rinse everything until completely clean. Two cans took care of 1 - 18,000 and 2 - 9,000 btu units.

This stuff works so well. I was cleaning my moms air conditioner and she has had it for over 5 years never cleaned it. This stuff did eberything it says it would do. I did what the directions said to do and it started working in 5 minutes. When I tell you that foam took all the dirt off it literally did. It was eating away at it and it was melting off.

Best stuff ever for cleaning your outside HVAC System. I should have bought 2 cans but still completed the job. At 65 I still have it in me to do this myself. There was sooo much dirt inside and outside of the system I didn’t think this would do the job. I haven’t cleaned it since the townhouse was built almost 5 years ago. From all the construction back then it made a mess everywhere. Now I know it will run more efficiently for me. Best stuff to buy, It really did the job!! Beats paying a Company charging 2 Arms and 2 Legs to do this! 😂 Keeping my $$$ in my pocket!

Super efficace et facile à utiliser

Worked well followed the instructions for once and it did what it said it was going to do dissolve the dirt and then I just sprayed it off.

Nettoie très bien, odeur agréable

Bad canister

I got this trio as a few years back I did not know the grid in an AC needs regular cleaning and I had to ditch an insanely good powerhorse AC cause of that ignorance. Since then EVERY YEAR I spray my whynter 14,000 BTUs with these sprays. I also do the split unit. So glad I found this spray. My Whynter has been going strong for the last 7 years. Cleaning my ACs has become a right of passage every year. It pays off in extreme heat alters when my place is a frgid 18C while outside there is a humidex og 45C. Cannot praise this product enough! I wish they would come in spray bottles instead. Not for some environmental reason but to get every ml of it intead of a useless at the end aerosol spray cans. Product deserves a 85% score. Still room for improvement!
