Install a Fan for the Whole House As a Cheaper Alternative to Air Conditioning
If your air conditioner is too expensive this summer, look for a home fan. They cool your home by removing hot air and blowing it out through windows or ceilings in the attic.
By removing hot air from your home, you have the added benefit of air circulation, which helps prevent indoor air pollution and allergies that can occur from stagnant air filled with pollen.
Whole house fans are n’t cheap, but they can pay for themselves after a couple of years of use, saving money on your electricity bill. They are easy to install, but you need to make a hole in the ceiling and move around in the attic, which can be tricky.
The video link below offers an easy installation method that won’t take more than a day.
