A: Air pressure is what you measure with a tire gauge. Atmospheric pressure is what you measure with a mercury barometer. … Pressure is the amount of force per unit area that a gas exerts on a surface.

What causes negative air pressure in house?

Negative air pressure occurs when air leaks out or into the ducts. Luckily, this is avoidable. Pressure test and measure leakage from your ducts to ensure that they are well-sealed. In addition to negative air pressure, the Department of Energy states that poorly sealed ducts contribute to higher energy bills.
