Lubegard96030 Kool-It Evaporator and Heater Foam Cleaner

I’m really impressed with this product it actually works. I was dealing with a persistent mildew smell in my 2021 Acura TLX, and after using Kool-It, the odor is completely gone. The air smells fresh again, and the difference was noticeable almost immediately.The only challenge I had was feeding the hose through the A/C drain tube — it was a bit tricky in my car model but that’s more about the vehicle’s design than the product itself. Once applied, the foam did its job perfectly.

2007 Ford Expedition EL Limited front evap has no filter (bad design imo), 267k miles. It works by assisting the breakdown of the clogged fins. Remove blower motor and stuff wifh towel, also place towels on the floor board. Spray this stuf everywhere and let it sit for 20 mims. I used the tube and hooked it up to the air gun, filled up the 50 foot air hose hose with water and high pressure (125psi) rinsed the chemicals off. Then used a rubber hose attached the the tube and let it dance around in the evap box blowing it out more. Blows great now. See pix.

Works well. It seems one can was not enough. I had to do a second treatment. I also had to make an adapter for the end of the hose.. I feel the manufacturer should provide some kind of grommet so the foam can go up inside instead of blowing back in you face.

Worked on freshening my trucks AC. Arrived on time. East to use. Check out YouTube for video to access coil behind the glove box.

Put this in every year through the drain hose. Eliminates the smell and rinses the condenser. Easy ten minute job. Takes me longer to remove the floor mat than it does to use this stuff.

It was great until it wasn’t. Foam isn’t much inside. Instructions was to use the whole can. I used this for my 2024 Tesla Model Y Performance along with the cabin air filter replacement. This leaks a lot of the foam from the base of the nozzle, which probably at least 1/8-1/4 of the can. So far the odor disasseapeared when pair up with the Hepa carbon filter.

Pretty solid product. I've used it a few times over the years and found it to be very effective. It has a decent minty smell that I find disipates after a day or so unlike some harsher more "chemically" scented products.I've used it through the condensation drain or through the air intake vent on my windshield and it worked well either way.

The good: It has a straw that helps get it to the coil.The bad: 1) I purchased two cans of the Lubegard Kool-It Evaporator & Heater Foam cleaner. 2) The can contains only 6 ounces of 'foaming' cleaner. 3) It didn't help.(The first time:) I purchased this product on Amazon and I followed the packaging directions and online videos by the manufacturer and put the provided straw up the A/C drain of my vehicle. I shook the can well and dispensed it all into the tube. I used a borescope inspection camera with a light and I removed the blower motor from my vehicle and put the borescope through that hole to monitor the foam hitting the coil. The camera verified that it covered the coil, then I let it sit for about 30 minutes and ran the A/C as instructed to "self-rinse" the product off with the AC system. I do feel like the can was more liquid than foam, though. I did shake the can well before using.I feel as if the smell got worse.(The second time:) I bought another can of this same product through a local retailer that sold the same product, thinking, maybe I just needed to do it again. This was about 3 weeks later. This time, I used the borescope camera to apply the foam on the coil from above and not through the drain hose. I followed all the directions provided and let the vehicle sit for about 30 minutes, then ran it to self-rinse the product off with the AC system.I still feel that the coil smells as bad, if not worse.I wish there was a better way to access these coils rather than having to tear apart the entire dashboard. I have checked the entire dash with the camera, and it is clear.Anyhow, for $16-20/each for 6 oz. of cleaning product, I don't feel like it contains enough cleaner for the price. I should have shopped around more.Good luck with your A/C systems. Hopefully you have a better experience than I have.
