Does Closing Vents Really Help You Save Money?
No. In short, closing vents does not help you save money. Instead of helping the air conditioner cool less, closed registers force the same amount of air through other ducts. Closing HVAC vents may waste more energy than operating your system as usual, causing your system to work harder and possibly running it into the ground, requiring you to shell out extra cash for a new HVAC much sooner than you expected.
Why You Should Always Keep Your Vents Open
Keeping your vents open is beneficial, even in unoccupied rooms. When you keep your vents open, it:
- Prevents overheating and freezing
- Reduces pressure imbalance
- Promotes proper air circulation
- Prevents duct leaks
- Prevents carbon monoxide leaks
- Prevents system damage
The Right Way To Adjust Air Vents
Aiming and redirecting your air vents can help improve the efficiency of your HVAC system. There are several things you should pay attention to when adjusting air vents, including the positioning of where the vents are located.
If it’s hot outside and your vents are located near the floor, you should adjust the vents so that the cold air will flow upward. If it’s cold outside and your vents are located near the ceiling, you should point the vents downward.
You should also consider the layout and furniture in a room when adjusting the air vents. Because some older homes have air vents that are located near windows and doors, you need to make sure to redirect the air vents in these areas so that your conditioned air doesn’t escape. When airflow is obstructed, the majority of heating and cooling is lost, so your air vents should also not be blocked by furniture.
How Can I Make My AC System More Efficient?
There are many ways you can keep your AC system in good health and make it more efficient, including:
- Changing your air filters: Regularly changing your air filters helps your AC run more efficiently and lowers your electricity bill.
- Scheduling regular maintenance: Frequent AC tune-ups can reduce your energy costs by up to 30% and extend the life of your system.
- Unblocking vents: Keeping your vents open and free of clutter of furniture keeps your AC system in good health.
- Using a programmable thermostat: A programmable thermostat can automatically adjust the temperature in your home based on your schedule and preferences.
- Installing a smart thermostat: A smart thermostat can automatically adjust the temperature in your home to keep it cool without overstressing components.
- Using ceiling fans: Ceiling fans can distribute air more efficiently and can be used as a substitute for a heater or air conditioner.
