Keep Registers & Doors Open Across the House | A.J. Perri NJ HVAC Skip to content

Should I close registers and doors to areas of my home I’m not using?

No.  Every system is designed to cool a certain number of square feet.  By closing registers and doors in certain rooms, you disrupt and decrease the system’s airflow and efficiency.  You system will have to work harder to cool less space, making it cycle more and become less efficient.
