Summer 2017 is in full effect and the heat has been cranked up all over the nation. With most of the southwestern United States being slammed by triple-digit temperatures for a couple of weeks now, many citizens are looking for any relief they can find from the searing heat. To help alleviate some of the stress on home air conditioning, people have taken to building custom cooling units out of floor fans that can help provide extra chill without bumping up the output of the AC unit that is already likely working at near max capacity.

The process is pretty simple, as you’re basically building a free-standing evaporator that cools the air blown by the fan while it operates normally. With a small cooler full of ice pumping the chilled water through rubber tubing that’s attached to a length of copper tubing, which is then coiled and mounted to the front of the fan, the air mover suddenly works much more like an actual air conditioner, with the cooled tubing providing a noticeable drop in temperature over the air blown by the fan as it comes from the store.

With the summer just really getting started, don’t be afraid to head to your local hardware store and pick up the reasonable list of items to build your very own air chiller. You should also do everything possible to stay cool at all times, sticking to the shade whenever possible and only braving the heat when you absolutely have to. Extreme temperatures can wipe out your energy before you realize what’s even happening, leaving you drained and in need of medical attention if you aren’t careful. If you have to face the brutal conditions, be sure to drink plenty of fluids to stay hydrated. Also be considerate of pets and the elderly who may need special care in such a climate.
