I'm not sure that an evap cooler is viable anymore in our area... My understanding is that the cheapness of the materials that make up an evap cooler is a major factor in the lifetime cost. I know that I had to replace the pads each year, do some cleanout of the calcium buildup, maybe replace the rubber drive belt every year or so and replace the electric motor every 2/3 years. And after 8 years the rust was so bad that it would eat thru the cheaply protected body metal and so a new evap cooler was needed.
There are many houses with water leaks down the air shaft that require walls/ceilings etc to be repaired. Many times the float valve becomes rusted open and even though the electricity is off, the water continues to flow and if it is not noticed will start destroying the roof structure itself. It is a horrible waste of water in this era where we have a massive drought. The poorly manufactured and electrically inefficient motor of an evap cooler sometimes uses as much electricity as an Air conditioner. There are NO energy star evap coolers. I was told that there was a study that took all these factors into account and the conclusion was that an AC with an efficient motor/compressor used as a heat pump was cheaper over a 10 year period than an evap cooler. And a personal story - I had one in a newly built shop, full of nice metal tools. I noticed that slowly the tools started rusting up and required more maintenance to keep the surfaces clean and useful. I got a split AC and have been very happy with it.
