Or being difficult to open with a heavy draft that follows?

This is caused by an imbalance in pressure (static pressure) inside versus outside the building, directly related to system ventilation, ductwork issues and economizer set-up, these seemingly mysterious and hard to fix conditions often go neglected due to frustration that the issue doesn’t get resolved, we can help ease your frustrations!
