1. Make sure your home is properly insulated. This helps to keep the hot air out and the cool air in. The better insulated your home is, the less cool air it will take to cool it.
2. If your central A/C is over 12 years old, you may want to consider replacing it with a newer, energy efficient model. This could help you cut your energy costs by about a third!
3. Call GMC AC Services at least once each year to have your A/C serviced!
4. Ensure your doors and windows are properly caulked. A 1/8th inch gap in your doorway is essentially the same as a 6 in square hole in the center of your front door, you'll lose a lot of cold air!
5. Get your windows Energy Star qualified!
6. Purchase energy saving light bulbs for your lights. Using these bulbs can cut a great deal off of your energy bill.
7. Install a programmable thermostat. It only takes a few minutes to program but the benefits will be endless. These thermostats can be programmed to turn up the A/C when you're not home and cool the house down when you are!
8. Install ceiling fans in your home. They consume less energy than your A/C and can save you money while keeping you cooler.
