Closing vents in unused rooms to lower energy costs is generally not a good idea as it can increase your energy bills by making your HVAC system work harder due to increased pressure in the ductwork; most experts recommend keeping all vents open for optimal efficiency.
Key points about closing vents:
- Myth of saving energy:
Contrary to popular belief, closing vents does not redirect air to other rooms, but instead puts more pressure on the system, forcing it to use more energy to maintain the desired temperature.
- Potential damage to HVAC system:
Excessive pressure from closed vents can strain your HVAC system and lead to potential damage over time.
- Air leaks and discomfort:
When you close vents, air may find alternative escape routes through leaks in the ductwork, leading to uneven temperatures and discomfort in other areas.
