Clear area around heating and cooling vents

Why? Furniture, carpets, and other objects can block vents and prevent heated or cooled air from traveling. This blockage makes your heating or cooling system work harder and prevents rooms from warming up or cooling down quickly. 
How it works: Check the placement of carpets, couches, beds, and other large pieces of furniture to be sure they are not blocking vents.

    Good to know:

      • Don't close vents. Closing the registers in unoccupied rooms may not improve the efficiency of your heating or cooling system. Closing vents can increase the pressure in the duct system, causing air leaks from cracks or holes in ductwork to increase. If this air leakage occurs in unconditioned spaces, like an attic, crawlspace or garage, it can reduce any efficiency gains from not heating or cooling the unoccupied room.
      • Heavy dust on a particular vent may indicate leaks in that portion of the duct system. If you see this condition, inspect the nearby ductwork to find leaks you can seal with mastic.
