HVAC GUYS Foam Blaster AC Coil Cleaner Foam Spray | HVAC Coil Cleaner for AC Unit | Professional Deep-Penetrating Formula for Evaporator (No Rinse) & Condenser (Light Rinse) - 3 Pack

This cleaner sprays into your coils as a thin stream and then expands into a larger foam on contact. This works and cleans surprisingly well and I can definitely recommend it. Also, the scent is of gentle citrus, and is delightful. I’ve used it indoors on convector coils and am very happy with the results!

Purchased three cans of this product to clean my AC unit outside on each of the three side. unit is an old 2019 Carrier and boy did it clean some serious junk off. Dirt, pollen, mold, mildew, etc. While you don’t need to wash off I did to get the remaining funk off the unit. Noticed an immediate improvement on the unit and the overall operation of the AC in the house. Purchased six more cans as I plan to clean the unit more often during the summer months.

I used this on my indoor window AC (U shaped) and it worked perfectly. My ac unit didn't smell bad (no mildew or anything like that), but it didn't smell clean either, if that makes sense. This has a clean, almost citrus-y scent and foams up as soon as it hits the fins on the coils. I was worried because it doesn't come with a straw to direct the spray but it comes out in a straight stream and is easy to aim. I let it sit for the recommended amount of time and then rinsed with distilled water. If it was full on summer with humidity I wouldn't have even needed that last step because the condensation would have rinsed it off. I was expecting bad times because of the warning label but it wasnt bad at all and I just left the bathroom fan running. Definitely would recommend for window AC units if you can easily reach the inside coils.

Works well. My old ac was cleaned well but they had simply died and I had to replace them, so I will be using this in the future for my new window ac units! So easy and simple to use, the amount of dirt that it removes was amazing and barely anything to clean up dried up nicely i just wiped the window sill off a little bit other than that really powerful stuff!

Very easy to use and no need for an expensive AC company! I have a 3 ton unit and I needed 2-3 bottles. Really works great! It says that you don't need to rinse it off but I still did after I let it soak for a while. Just gave me a better result. No leakage problem, smells neutral - a little like lemon - and is also safe to use.

Works good. Cans run out fast. But they do clean coils great. Good orange smell too. Used them for equipment a/c evaporators and heater cores.

Did the job I was hoping for. I used it on my Heat Pump and it did a great job cleaning the gunk off of the coils.

Worked amazing, made it was easier and efficient to clean the unit.

We have used this on outdoor and interior components of our "minisplit" system. Works very well. Excellent aerosol can that has distributed all of the product evenly. Foam is not too noxious and does a great job breaking down dust and moldy crud from the interior blower (Plastics), and metalic fins . We recently re-ordered another 3 can batch. ( 3 cans so far have washed up 6 heads and 3 exterior units). We have moved to wash with light water afterwards (Spray soak and wait 20-30 mins for foam to soak/ and melt away, then low pressure spray with warm water and the goop flushed clear ). Using a HVAC raincoat/funnel and hand pump seems good)

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.

Cover the entire coil and evaporator with the foam and let it sit for 15 mins, Don't skimp on the area that needs cleaning. The can says 10mins, i did 15mins. Works great. Cleans everything off. Used on my home ac coil and car evaporator and radiator. Noticeably cooler ac air in the car and fresh (remove filter before cleaning, replace with new). Planning on using this in the car vents if the smell comes back.

Bad canister

I took the covers off and sprayed the cleaner on the embedded dirt. This side took an entire can so you will need 2-3 for a large AC. Waited 15 minutes then sprayed water from the inside out. The fins are clean and the AC works like new again. The whole process of unscrewing and removing the panels, cleaning then putting back took about 45 minutes
