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

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.

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.

This stuff was amazing. It did exactly what it stated it would do for me dirty coils, completely clean, and the odor is gone inside the house from pets. Good job guys.

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

Great stuff. Worked perfectly and easy to use. Air conditioner hadn’t been cleaned in 3 years! Looks brand new.

Works great. Smells good. Easy to apply. And makes my AC run much cooler and better. Definitely will be buying again

Watched a few videos before making this purchase. The day of cleaning, I removed the top of the ac unit along with the side covers. Lightly vacuumed the coils and bottom and then sprayed the inner and outer coils with the cleaner. It didn't seem to spray out and foam as much as what I watched in the videos but it did appear to work at getting the grime to the surface. Afterwards (15 min), I hosed off the coils several times and they looked pretty clean. Overall I'm satisfied with this product, the citrus scent was not overwhelming and I went through 3 full cans to do my 3 1/2 ton condenser.

This foam blaster is a game-changer for keeping my AC unit in top shape! It makes cleaning the coils so much easier and faster than I expected. The foam expands nicely and gets into all the nooks and crannies. My system is definitely running more efficiently after using this product. I highly recommend it for anyone looking for a simple yet effective way to maintain their air conditioning.

This stuff works great!...having a retired uncle in the HVAC, he tought me to make sure the condensor & coils were always in tip top shape, in doing so keep them clean. Although he didnt use this stuff, he was on the commercial side - i tried it and can tell it works great.

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.

Good

Bad canister

used 2 cans to spray on my outdoor ac unit, foam works its way into the fins really well before I did the final rinse with a garden hose on light spray
