Review on 1-Gallon Nu-Calgon Evaporator Power for Enhanced Performance by Mark Ponnusamy

I have been very pleased with the results I have been able to achieve with this product. I had to apply it to the vaporizer several times to clean it. My coil had 7 years of sediment clogging the coil and drain. After spraying with a pump sprayer, about half a gallon of cleaner (about 5 uses of cleaner per coil, top and bottom). Each application lasted 20 minutes. The sediment softened and began to drip off the spool. I used an air nozzle to clear the mud from the coil and drain pan. This will create a mess so be prepared before you start and place a sheet of plastic to catch anything that comes out of the A/C coil on the floor. This product takes time to work and does not require rinsing. I would recommend trying this out before spending $500 or more on a service company. My air conditioner works great. I would recommend this to people who know how to use tools and are skilled enough to turn off before touching the device.
