HVAC energy saving tips

Heating, ventilation and air conditioning (HVAC) can account for a big portion of your energy bill. The good news is that there are many ways you can improve HVAC efficiency and save.

Save 2% to 3% for every degree the temperature is raised in the summer or lower in the winter.

Make the most of your thermostat

Changing the temperature just a few degrees can make a big difference in energy use. You may be cooling or heating your business more than needed. See the table below for recommended settings.

Try these temperature levels:

Occupied/business hours Unoccupied hours
Cooling season 78°–80° F Above 80° F
Heating season 65–68° F 60°–65° F

Some other tips to keep in mind:

  • Make gradual changes. Changing the temperature gradually, say by one degree every week or so, gives employees time to adjust.
  • Experiment with settings. Try different temperature settings to see how high in summer or how low in winter is still comfortable.
  • Consider locking devices. Installing locking covers on thermostats can help you maintain desired temperature settings.

Check thermostats for accuracy

If you have an inaccurate thermostat, energy dollars may be going to waste. Judge the accuracy of your thermostat with one you're sure is correct. Once you know how many degrees your thermostat is off by, you can adjust the settings accordingly. For example, if your thermostat is off by four degrees, setting it at 82° will give you a true 78° temperature.

Reduce HVAC running time

Turn off or reduce the air conditioning or heat a half-hour to an hour before closing time. It should remain cool or warm enough inside to keep people comfortable.

Exceptions include the following:

  • Health or building codes may require minimum ventilation at all times.
  • During the winter, turning off a heat pump that has auxiliary heat strips may not result in energy savings unless the heat pump has a smart thermostat.
  • Heat pumps that will be shut off in cold weather should have crankcase heaters.
