Swamp Cooler Owners - have your swamp cooler winterized.
Because your evaporative cooler has a water supply line that is connected to it, you should winterize it to protect it from bursting should there be a freeze during the winter months.
Your evaporative cooler has metal working parts that as you know water and metal after time will rust. All through your cooler may have a plastic parts in the reservoir section of your cooler, there are other parts such as your water circulating pump and motor that should not be left with water in a confined area without air circulating around it. Standing water will cause damage to these parts and to the cooler in general. Corrosion is the number one killer of evaporative coolers!
Using winter protective covers are a great way to keep your cooler clean during the winter months. After cleaning your system thoroughly, you should cover your cooler. Protective covers keep winter dust from getting into the motor and air ducts so when you turn your system on.
Your evaporative cooler is an investment in your home and should be maintained to insure that it is in proper working condition when it comes time for summer. Maintaining your evaporative cooler with proper startups and winterizing your Cooler will insure many years of worry free comfort.
Take care of it and it will take care of you!
