Does Closing AC Vents During the Day Help?

Does it help to close vents in rooms not being used during the day?

The answer to this question is very site specific and dependent on several factors, such as: heating, ventilating and air conditioning (HVAC) system design, location of the thermostat, house design, and climate, according to ENERGY STAR. In the right situation, closing vents and doors to certain rooms that are not being used during the day or even during a whole season may reduce heating or cooling bills. However, when you close vents and doors you could also throw off the balance of the system, change the way air is distributed, or cause the thermostat to detect temperatures which make the rest of the house uncomfortable.

Check with AirNow during your tune-up. Ask which doors or vents you want to close and why. We will be able to help you decide whether certain doors or vents can be closed to reduce the amount of space in your home that is being heated or cooled.
