Should House Vents Be Open Or Closed

These vents allow outside air to circulate under the floor in summer to prevent the moisture buildup that encourages mildew and rot. In winter, when the air is drier, the vents are closed to reduce the chance that the pipes in the crawl space might freeze.

The prolonged presence of wet air underneath your house can prevent the crawl space from drying out completely, which can lead to mold and dry rot. A good rule of thumb is to close your crawl space vents once the outside temperature starts dipping down below 40 degrees F. Tip: Open vents when over 70 deg F. Close vents when under 40 deg F.

When you shut off the vents, you can increase the pressure in your ductwork which can back up into your HVAC and cause issues. The issues your HVAC experiences due to closed vents are like problems caused by dirty air filters including inadequate airflow, turning off and on frequently, and premature HVAC breakdown.

This results in additional wear and tear on the unit, and makes it harder for the HVAC system to regulate the humidity level in your house. So your best bet is to leave the heating/cooling vents open in all the rooms of your house, and keep the doors open as well.
