Like the condenser coils mentioned above, using force to spray from outside in can cause deeper clogs. Purchase a pump sprayer, professional cleaning solution, and brush. If foam during cleaning and brightened aluminum fins after cleaning are desired, select any one of the Nu-Calgon "Brite" products (Alka-Brite, Nu-Brite, Foam-Brite). As dirt and dust accumulate, heat transfer is reduced, resulting in a higher head pressure which in turn brings about increased power requirements and loss of efficiency; remember, for every 2°F rise in condensing temperature, efficiency drops 1% and power consumption increases 1%. This restores designed heat transfer and air flow. Use of the Teflon-based coil protectant, Cal-Shield, will help the coil to repel moisture as well as dirt, grease and grime.
