Using less energy can mean a great deal of savings, and saving money definitely interests most people. So a question we commonly get asked is: If you close vents in unused rooms, will this result an energy savings?
Simply put, the answer to that question is no.
If your heating and air system is equipped with a forced air system the way most new homes are built nowadays, you will not actually be saving money. Here are the reasons why:
- Closing vents puts extra stress on your system. Often, the ducts have so much pressure put on them that higher utility bills can occur due to ruptures and leaks.
- Frozen coils can occur because there is damage to the compressor due to restricted air flow.
- An appropriate amount of air is distributed in each and every room according to the professional calculations that were made before the house was built. This determined the size of the HVAC system needed to heat and cool your home. You will not achieve the goal you are after by closing vents. The air will still flow and actually just cook the inside of the vent.
