HVAC
Heating, Ventilating, and Air Conditioning (HVAC) may be the biggest user of energy in your building - about 42% of your total energy bill. To trim those bills remember to turn it off when not needed; run it less; and make it more efficient. Get the most out of your HVAC.

Controlling thermostat settings

  • During the summer months, set your thermostat at 78 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 can really pay. Your savings will depend on how much you lower the thermostat setting and how cold the climate is.
  • Place a locking device over thermostats, if necessary, to keep employees from adjusting the temperature.
  • Eliminate unnecessary use of your HVAC system during unoccupied hours. When your building is unoccupied, adjust the heating and cooling system's temperature accordingly.
  • Install a programmable thermostat or a time clock to help ensure regular temperature modifications and early morning comfort.

Properly maintaining your HVAC system

  • Replace air filters regularly
  • Make sure your thermostats give true readings. If a thermostat setting is 78 degrees but the real temperature is 75 degrees, the cooling units are running much more than necessary.
  • Inspect duct work, repair leaks large and small. If you have a forced air system, make sure the ducts are delivering all the heat and cooling to where they're needed.
  • Have your heating and cooling units regularly serviced by a licensed contractor.
  • Have your contractor: Have your contractor:
    - Select the best heating and cooling system settings
    - Test, clean, and adjust your boiler or furnace
    - Adjust air ducts registers
Buying efficient equipment
Cooling equipment failures can put you out of business while you're waiting for repairs or replacements. If your air conditioning unit is over 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.
