The truth is that you probably have more important things to do with your day than regularly inspecting and changing the air filters in your building. Even if you were able to set aside the time to do this, it is always better the have qualified HVAC personnel take care of this for you.

Setting the thermostat to the extremes of hot or cold may make you feel better, but it will not adjust the temperature any quicker than if you simply set it to a comfortable temperature.

4. Don’t turn off the AC when you leave for the day, it will take more energy to start up again!

5. It doesn’t matter where you put a thermostat

Thermostats read the temperature in the area of where they are placed. If you have put a heat source near to a thermostat it will give a false reading of the ambient temperature of the room, this is especially true in large open spaces such as factory floors and open concept office spaces.

6. I can save money by closing a vent in a room that is not in use

All you will do here is through of the balance of the HVAC system. Closing vents can also cause a build-up of pressure in the ductwork.
