Heating, Ventilating, and Air Conditioning (HVAC) may be the biggest user of energy in your building - about 42% of your total bill. To better manage or trim your costs, remember to turn off heating and cooling when its not needed. If necessary, make improvements to get the most efficiency out of your HVAC - run it less; and make it more efficient.
Controlling thermostat settings
- During the summer months, set your thermostat at 78°F degrees or higher. For every degree warmer you'll save about 2% on your electric bill.
- During the heating season, keeping the temperature a little lower if possible. Your savings depend on how low the thermostat is set and how cold the climate is.
- Place a locking device over thermostats, if necessary, to keep employees from adjusting the temperature.
- Reduce unnecessary use of your HVAC system during unoccupied hours. If your building is unoccupied, adjust the heating and cooling system's temperature.
- Install a programmable thermostat or a time clock to help ensure regular temperature modifications and comfort when you need it.
Properly maintaining your HVAC system
- Replace air filters regularly
- Make sure your thermostats give true readings. If your a thermostat setting in the summer, for instance, is 78°F degrees but the real temperature is 75°F degrees, the cooling units are running much more than necessary.
- Inspect duct work and repair leaks. If you have a forced air system, make sure ducts are delivering all the heat and cooling where needed.
- Have your heating and cooling units regularly serviced by a licensed contractor.
- Have your contractor:
- Select the best heating and cooling system settings for you
- Test, clean, and adjust your boiler or furnace
Buying efficient equipment
Cooling equipment failures can cost a lot and take a long time to repair. If your A/C unit is older than 10 years old, consider replacing it with a high efficiency unit. This may be an opportunity to upgrade your HVAC system to a high efficiency unit and lower your energy costs.
