Energy Saving Tips for Common Components

A/C Tips

Surviving a hot summer often means running your air conditioning regularly, and keeping your home cool all summer can be costly. Follow our A/C energy saving tips to save on air conditioning costs and be more energy efficient:

  • Raise your thermostat to 78 degrees when you are away for eight hours or longer. You will save approximately three percent on your cooling costs for every degree you raise your thermostat,.
  • Be sure to clean or replace filters on a regular basis. Clogged filters block air flow, which can increase your A/C’s energy consumption by five to 15 percent.
  • Keep your window shades or curtains down during the day to keep sunlight blocked when the air conditioning is running. Sunny days can make your air conditioner work two to three times harder.
  • Use an interior fan to spread the cool air without having to increase the power used by your A/C unit.
