Maintaining your swamp cooler or coolers is time consuming. to make sure that your swamp cooler is running properly and efficiently you need to thoroughly clean and prep your cooler, including removing scale build-up from pads and water lines, pump and through-out the system. Depending on how hard your water is this chore alone can be quite time consuming and tedious but is very important if you want to keep your home cool during the summer. When water build-up is not removed it will eventually come loose and clog your lines in turn blocking water from getting to your pads.
