Nu-Calgon 416808 Evaporator Power, 1-Gallon

I am getting 10-1 codes on my fujitsu solit system when i use heat. The thermistor is fine so I was told the cage is dirty. Water didn't clean it enough as there was still green and a lot of buildup on the inside. I used this, outside unit, with 3 parts water and 1 part formula. I did two passes with a water rinse. The cage looks brand new. Distilled water The scent is negligible. I will be using this on the inside unit coils and wheel. Highly recommended. I used a pump sprayer to apply.

This stuff is great. I live in SFL where we use the ac a lot. In addition to general dirt collecting on the coils, there is humidity and the condensation drain pan and lines clog with algae. I’ve been using this monthly, for two years, applying it when I change out the filters. The coils still look polished/new, the machine is just over 2-years old. No algae clogging things up either. I also have a rental with a 10-y/o system that would need annual maintenance to un-clog the drain pan and lines. Since I started using this product, I haven’t had any backup issue, and it is still cooling well. I also used it on a wall-banger and had good results. This is part of my monthly maintenance routine and after two years of use I think it is effective and great value. It is a maintenance product, not a miracle genie. If your coils are gunked up bad you probably need a pro to acid wash them, then start using this so stuff doesn’t build up again. Use good filters too.

I watched a youtube video on how to clean our mini split air handler or head. The metal fins will begin to get clogged with dust and the squirrel cage fan will also grow mold causing the unit to put off a dirty tennis shoe smell. After watching the YOUTUBE instructions and following the directions,lightly spraying the evaporator cleaner on the surface will cause the dirt and grim to fall off very easily. We can clean our systems simply, easily and efficiently whenever needed. This Nu-Calgon product is one of the best tools!

Seems to make a lot of solution. From what I remember of my organic chemistry, it looks like a combination of a detergent and an alcohol. Came quickly in the mail. I used it on my 12 yr old mitsubishi split system in my master bedroom (this is the first time I cleaned the evaporator), using a one-gallon spray pump. It does clean the air handling unit pretty well: areas at the base of the fins (in the valleys) are very very clean. Most of the wastewater actually drained down the drainage tube. I still had to brush off the lint that stuck to the top of the fins (gently, with a toothbrush), and the large plastic bag that I used as a catch-all caught this. A/C is now cold! I did not buy any kits to collect the wastewater. I used a large plastic bag that a new bedframe was in. It worked fine. I just used painter's tape to secure it to the air handling unit but also left the bottom of the plastic bag in a large ice cooler chest. I made a gallon of the solution and now I have a fair amount left over. I thought I could clean the a/c units in my cars but the evaporators are difficult to access. I then used some of it to clean the fins on air handling units in our Central Air, but even after 12 yrs of use, the central air AHU's were still pretty clean anyway. Maybe I would have had an easier time cleaning the fins if I had a pump sprayer that could spray with more force. The price does vary over the internet. I got mine for about $36.

Works great

Works well on mini splits coils. Cleans everything out

This helps keep the coils cleaner, but, does not cut the gunk as others claim. The AC is still working, but, it is only a patch. When someone finds the best solution, please let me know!!
