My husband and I bought an old victorian style house (two stories, built in the 1930s). It has been well kept and up to date (not deteriorating, updated electrical etc) except for that there is no central air system or air conditioning, and after one excruciatingly hot summer we've had it! I have been researching affordable ways to cool our house and have discovered the "Two-stage evaporative cooler." It is supposed to be similar to a swamp cooler, but without the "swamp" humidity, and more energy efficient than a window air conditioner, and less expensive than completely revamping our heating and cooling system. We live in semi-arid to desert climate (temperatures often reaching 100 degrees in the peak of summer, with relatively low humidity, except for the occasional thunderstorm). Where is the best place to buy (or the best brand to buy) and how should we go about installing one? All input is appreciated!!
