1. Make sure to replace your air filter once a month! Replacing your filters allows more air to better circulate through your entire house! 2. Switch over to LED light bulbs! LED bulbs produce light without generating extra heat in your house. Also as an added bonus, they will last up to 20 years AND they use less electricity than a normal fluorescent bulb! 3. Fans, fans, fans! Using fans to your advantage will not only keep you cool, but will also keep your electricity bill
