Foaming Coil Cleaner - 32 Fl Oz

I’ll confess…. like so many others, I’ve never given a thought about cleaning the coils on my central air conditioner. Then I saw a YouTube video and figured why not? I ordered this product, and today (a couple of days before we hit a stretch of 80’s this week) I went out and did it. I noticed last summer that the performance had gone down a little - especially on the hottest days. Taking off the outer jacket panels was simple enough. I was careful not to lose any screws AND to not strip them out when re-tightening them. I was a little surprised at all the grass and dirt inside, but what else could I expect after 15 years of never cleaning the coils. I gently brushed off the grass, leaves and dirt, and then sprayed the coils down inside and out and let it sit for 5 minutes. I then rinsed them off and repeated the process. A LOT of dirt was running out with the water after the first application, and much less the second time. It looked a LOT cleaner. Not perfect, but clean, as the aluminum fins will oxidize regardless. I put the jacket back together (no extra or stripped screws), turned on the power and set my thermostat for 60 degrees to make sure it still worked. It did! Of course the air outside was in the low 60’s so I can’t quantify how much of a change it made, but I figured it was the equivalent of changing a clogged filter that hadn’t been changed in 15 years. If I called a local HVAC service company to do the job I’ll bet they would’ve charged me a minimum of $150 to do the job, so I’m liking the 90% cost reduction by doing it myself. I trust my HVAC/boiler/fuel oil guy implicitly to be fair and do a good job, but this took less than an hour and there was little risk of me damaging anything. I doubt I’ll be doing it religiously every year, but I’ll definitely be keeping a closer eye on it.

Bought this last week to prepare for using the AC. We are in an unexpected heat wave for this time of year, and this stuff worked wonders! Got so much more gunk off the coils than the product we used last year- and the air has been feeling great since turning it on. Husband said it was easy to use, he liked how quick the job went, and overall was a good purchase.

I recently used the Simple Green Foaming Coil Cleaner 20oz to service my home’s HVAC unit, and I am beyond impressed. If you've been putting off cleaning your coils because it seems like a chore, this is the solution you need. Why It’s a Must-Have: Powerful Clinging Foam: The foam really stays where you spray it. It lifts dirt, dust, and grease out of the fins effectively, reaching deep into the unit where a brush or cloth simply can't go. Convenient Design: The ability to spray upside down is a total game-changer. It allowed me to get into the tightest angles of the evaporator core without the can sputtering or losing pressure. Professional Results: After one application and a quick rinse, my coils looked brand new. I’ve noticed a definite improvement in my unit's efficiency and air cooling speed since the cleaning. Safe and Non-Toxic: I love that this formula is self-rinsing on condensate coils and has a very mild scent. It’s much more pleasant to work with than the harsh, caustic chemicals found in other industrial cleaners. Final Verdict: This is hands-down the best DIY maintenance product I've bought this year. It saved me a $150 service call and did a professional-grade job in about 20 minutes. Highly recommended!

This coil cleaner works well for maintaining AC units-- sprays easily and helps remove built-up dirt and grime from the coils. It’s straightforward to use and doesn’t require complicated setup. The foaming action helps reach into tighter areas, and there’s a noticeable improvement in cooling performance after cleaning. It also feels like a good value, especially in a multi-pack. Only minor downside is that the foam performance can be a bit inconsistent depending on how it’s applied, but overall it gets the job done well.

I used the VAC Guys Coil Cannon AC Coil Cleaner Automatic Foaming Mixing Sprayer together with Simple Green Foaming Coil Cleaner, and the results were excellent. This is not a quick maintenance job. It took some time to remove the fan and motor assembly, take off the four side panels, vacuum out leaves and debris, and then thoroughly spray both the internal and external coils. However, the process was straightforward and the equipment worked as expected. Pros: Very effective cleaning Foam application makes it easy to cover coils evenly Noticeable improvement after cleaning Cons: Time-consuming process Requires partial disassembly of the unit Overall, the effort was well worth it. Having clean coils before the summer heat kicks in gives peace of mind and should help with system efficiency.

It works as expected, coils looked great after spraying inside and outsides of coil and letting it work 5 Minutes before rinsing. I was expecting more foam, it did foam up mildly but it worked great

Excellent cleaner for the outside compressor and inside condenser coils. These cans are heavy and have plenty of cleaner for a few units. I will definitely buy again.

Simple Green foaming coil cleaner worked great. Just spray the cleaner on and let it set off 15 minutes the rinse off.

Works great for cleaning my AC coil. Added some cleaning solution into a small pressure sprayer and water pumped it up and hosed down the coil, used water hose with nozzle cleaned it all up, ready for the season, do it again next year.

Muy util para limpiar los serpentines metálicos de una unidad de minisplit. Es importante notar que el producto debe diluirse con agua, y se debe utilizar un atomizador que tenga una bomba de presión.

Funciona muy bien para limpiar los serpentines tanto del equipo de afuera como el de adentro
