Frost King ACF19 Air Conditioner Coil Foaming Cleaner, 19 oz

My HVAC desperately needed to be cleaned. I watched a few videos and my son and I used this product to help wash away some of the grime and build up. It worked great!! I didn't use the scrubber on top but it is a nice feature. I did buy two cans because I knew one probably would not be enough. I would definitely recommend this product and will use it the next time! The price was great too!

I have been purchasing this foaming cleaner for years to clean both my HVAC condensers as well as my Automobile condenser. It is very effective at cleaning and deodorizing the coils without using harsh chemicals. I clean my outdoor HVAC condensing unit each year before summer heat starts. I start by rinsing with a garden hose then remove the top fan cover by removing the screws all around, then spraying this coil cleaner generously both inside and outside; let it sit for about 5 mins or so and then rinse it off with garden hose ensuring no fins are bent during this process. I was surprised how much dirt and debris is trapped inside those fins...very satisfying to know you are increasing the AC's efficiency. On my Automobiles, I spray this through the AC condensation drain tube which is typically located under the car right behind the engine firewall...its a black tube that drips water when the AC is ON. Spray into this coil cleaner with a tube until it cannot take more; then block the tube with a stopper for about 5 mins and then let it drain completely....you will be amazed to see so much gunk come out. it not only cleans your evaporator coil but also deodorizes your air blowing out of your vents.
