Should I Close Vents In Empty Rooms To Save Cooling Costs?

The ventilation of the house defines the way the air circulates between the rooms, but also between the house and the exterior environment. The HVAC abbreviation known everywhere for “Heat, Ventilation and Air Conditioning” is the technology that ensures indoor comfort, aiming to provide thermal comfort and acceptable indoor air quality.

A correct, efficient Denver air conditioning ventilation system according to the needs of the house allows an optimal air circulation and purification, keeping away dust, allergens and unpleasant odors, controlling humidity levels and keeping the air fresh in the house.

Permanently closed vents and low temperatures in empty rooms will eventually lead to condensation, which can cause mold formation. Besides, the level of carbon dioxide in unventilated rooms can exceed the maximum allowed.

In this context, closing vents in empty rooms to save cooling costs is definitely a bad idea, because you will modify the pressure involved in proper air circulation throughout the entire home, which will make you run into problems.

A HVAC system that works properly involves a certain amount of air being pulled into the system, which matches the air volume being blown out of the vents. When you close a vent, the air pressure in the air ducts can become too high and cause different problems leading to costly repairs. Obviously, in this case, your goal to save energy costs will be completely ruined.
