How to build a homemade air conditioner / evaporative cooler. I made this cooling system to save money on my summer electric bill. I used some wood scraps, a pond pump, some evaporative cooler pad, and a box fan to make a working swamp cooler air conditioning unit. It can achieve indoor temperatures that are 20+ degrees lower than outside temps.
