Heating and Air Conditioning Tips

In spite of San Diego’s moderate climate, heating and air conditioning are a necessity for most businesses. Even small operational changes can sometimes add up to big savings:

• Pay attention to your thermostat settings. Air conditioning thermostats should be set no lower than 78° F; each degree you raise your temperature setting can save on air conditioning costs. To achieve similar savings when heating, 68° F is the recommended temperature.
• Install programmable thermostats or timers to give you better control when the heat or air conditioning is on. Programmable thermostats also will help you control the temperature you want to maintain.
• On hot days, close the door and draw the curtains and/or shades to keep the sun out. During the heating season, take these same steps at night and during unoccupied periods to help your building retain heat.
• Weatherize your building by installing awnings, solar window shade screens or sun-control window film, and applying a heat-blocking coating to your roof.
• Perform regular maintenance to keep your heating and air conditioning systems running more efficiently.
