If you own a swamp cooler as your refrigeration unit to keep your home nice and cool during those hot summer months, the ideal thing you want to be able to do is to simply turn it on and then sit back and let it pump out the cool air all day. Most often this is exactly what happens and life goes on nice and cool during the summer. However, there is one thing that you need to remember is that it is pretty hard to recognize when your swamp cooler is not running as efficiently as it should be. Even if you turn it on and it starts cooling your home right away, you still don't know if it's working way too hard to get the job done.
You might want to think of your swamp cooler as you would your car. It has a motor and it takes certain energy to run it, just like your car. Consider your car, you change the oil, you change the spark plugs, you make sure the battery is charged and so on. Well these units also need regular maintenance in order to continue to run efficiently. Below are a few things to consider when it comes to the efficiency of the cooler.
If you want it to run efficiently you should try to wait for the temperature to reach at least 85 degrees F. This is going to save you up to 50 percent water usage. You also should turn the water pump on about five minutes before you go and turn the fan on. This will help to saturate the pads before you start using the cooler and it will help it work far more efficiently. Also consider including ceiling fans in your home to help circulate the cooler air around the house.
Before the summer months hit you should do a little basic maintenance on your cooler. You should remove the panels and then clean out any debris there might be in the pan that holds water at the bottom of the cooler. This will make sure that there is clean water getting into the pads and not water gummed up with leaves, dust and other junk.
Make sure to check the fan belt and see if there is good enough tension in it. When checking it, it shouldn't move very much, in fact it shouldn't be moving any more than an inch and even in some units that might be too much. If it seems too loose or is sagging then you need to replace it.
You should also make sure that you lubricate the blower assembly bearing as well as the motor and if if has an oil receptacle then put the right kind of oil in it. Take a look at the pads and make sure they are still in good shape and it they look worn then put new ones in. You will also want to turn on the motor and pump to see if the pads are getting water evenly. Also, if you notice any leaks, you really should call in a professional to take care of something like this.
