This time of year, you might need a reminder on how to save money with some simple updates to your daily routine. Replace dirty filters in your air-conditioning system once a month. If you're able to, have your outdoor AC unit under some shade. Doing so can help it use up to 10% less electricity to run. Finally, one of the best ways to save energy dollars is to use the air conditioner less. Open some windows and use your fans! The earth, and your wallet, will thank you!
