- 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) - 6 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.

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

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.

Yes you will need all three cans to do an outdoor unit. Seems to work well and the rinse off didn’t kill the plants surrounding the outdoor unit. Taking all the panels off the unit to get to the coils was the real challenge. Spray came out the can easily and foamed. It did remove easily with water and had no really harsh smell.

Good results with cleaning HVAC unit, spray is easy to apply and wash out with water.

This product really got the job done. My AC system was installed 5 years ago and I was quoted $800.00 to clean it. The coils and fins looked perfectly clean but looks are deceiving. After watching a few "how to" videos, I used this product to clean the compressor. Holy ravioli, the amount of dirt that came out was surprising. The process entails killing power to the compressor (MANDATORY), removing the top fan shroud and side panels, spraying the inside and outside of the coils and then rinsing with a hose nozzle set to shower mode. Please note that it took three cans to completely saturate the inside and outside of the coils and fins. Spend a few bucks more to get extra cans as it will be well worth it. The compressor was cleaned only two days ago so it's too soon to tell if it will be more efficient, however, the amount of dirt that came off was nuts. Two thumbs up.

Works great. We had to use all 3 cans on our 3 ton unit, probably could have used a 4th but 3 did a good job. Sprayed on and you can literally see the dirt coming out immediately. Let it sit til it wasn't as foamy and rinsed clean with water hose. I will continue to purchase and use at least once a year.

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

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
