If you're like most homeowners, there are probably rooms in your home that you don't use very often-- like your guest bedroom or a formal living room. It may be tempting to close the registers that allow heated and cooled air to circulate in those rooms. However, closing these vents isn't really a good idea. Shutting off the registers to some rooms in your home can actually end up costing you more money in the long run and even shorten the lifespan of your heating and cooling systems.
Why closing HVAC registers to unused areas of your home is a bad idea
1. A properly installed HVAC system is balanced.
This means that it is sized for the square footage of your home. When you close registers, it causes the system to be less efficient.
2. It stresses your ductwork.
The register is the end of a series of ductwork leading to your rooms. When you close a register, the motor is still sending conditioned air through the ducts, only to be stopped at the register. This pressure can cause leaks and other damage to your ducts.
3. Your system's motor has to work harder.
Trying to force that air through closed registers makes your heating and cooling systems' motor have to work harder, which can shorten the life of the system.
