Registers and doors

Should I close the registers and doors to areas of the home that I do not use on a regular basis?

Answer: No. Closing the registers will decrease the systems’ airflow and efficiency. Every system is designed to cool a certain number of square feet. By closing registers and doors in certain rooms, you disrupt the airflow and cause your air conditioning system to work harder to distribute air to other areas of your home. Your system will work harder to cool less space, making it cycle more and become less efficient.
