Reason for Cleaning of the Outdoor Coil

As dirt, debris, grass clippings, get on the coil, it acts as an insulator. And all heating and air is. Is transferring heat. So in the heating season, you're bringing heat inside the house, right? Getting cold out. And in the summer, you're throwing heat from the inside, outside, where it doesn't matter. So in that transfer process, you need everything to be clean. Otherwise, acts like an insulator, which will affect your energy bill, and it will make things like the motor, the compressor, all this work harder, which drives your energy bills up, as well as shorten the life of those motors. Compressors, capacitors, everything that's in line has to work harder because it's trying to transfer this heat. So you want to make it as easy as possible, and the easy way as possible for it to do it is to be clean.
