As air is pulled through a condenser coil, small amounts of dirt deposit on the fins. Left untreated, a layer of dirt builds up over time – acting as an insulating blanket and restricting air flow. This prevents effective heat transfer, so the system has to work harder to dissipate the heat. Energy consumption increases, and the life of the system may be shortened. Avoid all these problems by using Advanced Gel CC, with its powerful cleaning and brightening action.
