Nu-Calgon4168-08 Evap Pow'r No Rinse Coil Cleaner

I tend to obsess a bit about the wee beasties that breed in the cool damp environment of the A/C evaporator. I like things to be healthy and clean, who doesn't? I used this cleaner because it was safe for the plastic pan in my evaporator. Lots of cleaners will eat plastic so be sure you check for that when choosing one. It turns out that my coil, even though pretty old for a coil, was still clean probably due to the electronic air cleaner that sits ahead of it. Also I am a fanatic about keeping filters clean. I sprayed this as recommended on the coil anyway since I had the evap housing all opened up. The smell was pleasant and it seemed to wash down the coil very nicely. The scent went away within a hour and was a pleasant smell anyway. So for all my effort all I can say is that my clean coil is a little cleaner, perhaps I killed some germs, and it was good to see the pan wash down nice and clean due to the detergent action. I'd say this is good stuff and I have plenty left over to use again next year.

This is one area where you don't want to skimp when it comes to quality of product and the way it works. Getting cheaper here could mean spending way more money down the line because it didn't clean the way the Nu-Calgon products clean. Especially when talking about your evaporator coil...because it is often hard to see exactly what you are doing when working on this coil while it is in place...you need a product you can trust to do the job well. I admit I had let our HVAC get dirty and had no maintenance for a few years...I know...no need to reprimand. Fortunately, I received a warning call before a total breakdown...so I got busy and cleaned both coils...indoor and out...as well as the blower inside. Wow! What a difference? My system is staying cooler and working less to achieve it. In this heat in Texas...we have been averaging just under 100 degrees F...but you wouldn't know it inside our home. And our electric bill has shown us appreciation for this job as well. Who knew you could stay this cool and lower your energy bill as well. Cannot beat this cleaner! HANDS DOWN!

This is one of the best AC cleaner solutions we have found on the market. Our home is older and tends to attract dust. We even have pets that poof everywhere!Cleaning the AC units is a must as a preventative maintenance to keep our units running smooth and clean.Works best when you take the extra time to take the unit apart to apply.Not corrosive enough to damage your AC unit parts.Safe enough to use mid season in the morning, before the need for AC really hits.Great for home and office, around pets and children as it has a low odor.We have used this cleaner for years on fixed and removable air conditioning units and we recommend it to family and friends that like to save money.We recommend preseason use and mid season use for best results.

Worked very well. Air flows great and BTU exchange is back to where it should be! Be sure to clean off any excessive dirt/hair/debris first! I used a soft bristle brush attachment on my shop vac being careful not to bend the fins over. Much cheaper and just as easy as calling a pro in!

I filled a cheap garden pump, mixing the product with water as instructed. I removed the cover and then evap side covers and sprayed down the coil. I didn't do any scrubbing and the coil came out with a nice shine. I also sprayed around the inside of the plenum and the drip pan. Honestly, its harder to climb up into my attic than it is to clean with this product. I wish I could have bought a smaller quantity but I'll use the remainder outside on the compressor in the Spring.Only advice I can give is to open windows when you turn on your air handler after cleaning. Otherwise, your house will fill with the smell of this cleaning product. The odor can be pretty strong.Also, I read the warnings and wore painters overalls but next time I won't bother. I'll just use gloves and safety goggles.

The media could not be loaded. I used an HDX 1 Gallon Multi-Purpose Pump Sprayer followed the directions and mixed this with water 1 to 3 ratio. Spray the evaporator coil really well and let it sit for 20 minutes. Went back to help rinse it and it didn't look much different. I sprayed it for the 2nd time but still didn't look much different. This product didn't work for my indoor coil. Very disappointed.Uploaded before and after videos.

Washed the fins well without need to rinse. Yet after the cleaner sat on the fins 5-10 min, I still choose to rinse with clear water. I used a Porto Blaster pump which was great.

Cleaning A/C coils isn't rocket science. I used this product on both the inside and outside coils with great success. I have a coil brush to help remove things like dryer lint, leaves, palm tree detrius, and the like. I spray the coils from the opposite side of the air flow (which pushes the dirt towards the outside surface), let it sit for several minutes, then GENTLY brush the coils with the grain to loosen embedded debris. The outside coil, I flood the coils from the inside toward the outside to push out the dirt (use an open ended hose or a "flood" sprayer - being careful not to bend the coil fins). The inside coils make their own "rinse" from the condensate. Takes about 30 minutes per unit because some disassembly is required to get to the inside coils and condensate pan.As an added bonus, you can add some New Calgon "Pan Treat" to clean the scum from the condensate pan (and get rid of "dirty sock" syndrome). Helps keep the "biological material" down in your air handler.
