Closing unused vents may seem like an effective way to reduce heating and cooling costs, but it can sometimes compromise system performance.
In certain ducted systems, closing too many vents can increase air pressure, restrict airflow and reduce efficiency. Purpose-designed zoning systems offer a more effective solution by directing conditioned air where it's needed while maintaining appropriate airflow.
Before adjusting your vents, it's important to understand how your system is designed to operate.
