Don't Close Those Registers | Air Comfort HVAC


As we transition from summer into fall in Georgia and Tennessee, you might feel a little bit dizzy when it comes to your heating and cooling needs. Air conditioning on during the day and the heat on at night? The frequent switching can make your head spin. With all the changes, you might be tempted to close the registers in rooms that don’t need heating or cooling. Air Comfort HVAC is here to explain why that’s not such a great idea after all.

The truth is that even if you have rooms in your home which get less–or no–use, it’s important to leave those registers open to help ensure adequate airflow.

For folks wanting to save more energy at home, we know this must seem counterintuitive. No one wants to waste their energy dollars on cooling or heating unnecessary rooms, right? We understand. However, heating and cooling an entire house isn’t so straightforward. Let us explain.

Your HVAC system has been designed to heat and cool a specific amount of space. That’s why you’ll hear HVAC technicians talk about the necessity of a system that is the right size–not too small or too big. If you start closing off some of the registers, it affects the amount of space your system must heat or cool.

What happens after you close those registers? Your HVAC system faces a lot more pressure.

For HVAC systems with variable-speed motors, that pressure will make your whole system work much harder. That means your once energy efficient HVAC system is no longer so energy efficient. For folks with a single-speed motor comfort system, it won’t be able to maintain proper airflow.

Which means your home won’t be as comfortable.

Unnecessary pressure on an HVAC system is never a good thing because it contributes to significantly higher utility bills as well as much faster wear on the whole system.
