On sweltering summer days, everyone wants to crank up the AC and relish in the cool sanctuary of your home. But if your air conditioner isn’t working efficiently, you could be paying a high price for that comfort. The team at Advanced A/C Contracting in Honolulu, HI, specializes in helping residents get the most out of their heating and cooling systems. These HVAC experts say many homeowners make a big mistake when it comes to their air conditioning.

Many people assume shutting doors to rooms not in use will reduce the amount of space the AC system needs to cool, thus reducing the amount of energy spent. In fact, the opposite is true. Closing interior doors reduces your air conditioning system’s efficiency, which in turn means you spend more on utilities. This is because shutting the doors restricts airflow. AC systems are most efficient when there is an equal volume of air being dispersed and returned. When the doors are closed, the air dispersed to the closed-off rooms through the supply registers becomes trapped, creating an imbalance of air pressure. A prolonged air pressure imbalance can lead to air leaks in the system, which can result in a significant waste of energy.

Also, the indoor air conditioner is of a size proportionate to the square footage of your house, meaning it is designed to cool a specific amount of space. When the interior doors are closed, the AC system has to turn on and off more frequently and work harder to stabilize the temperature.
