I completely changed the design of the earlier version. For this DIY Air Conditioner, I made a channel-shaped heat exchanger to optimize cooling.Materials used:
• Aluminum repair roll ($10-15)
• Nuts, bolts, and washers ($5-10)
• Waterproof silicone ($5-10)Total cost: $20-35
The heat exchanger is made from straight sections of aluminum (cut from the repair roll) bent into a U-shape, and bolted together, as shown (Figure 1, 2, 3). Silicone was used to seal the gaps along the edges and around the bolts.

Cool beans, but… It’s almost wintertime!
An air conditioner is a very tough piece of equipment. It is engineered to withstand all sorts of abuse and keep on running. This’s great in most respects, but it can lead to complacency about maintenance. Like a car, air conditioners need regular tune-ups to run properly.
