also Should a house have negative or positive pressure? Neither positive nor negative air pressure in a home is good, as either puts pressure on the building envelope that promotes air leakage and they will each have different effects and impacts depending on the season, the temperatures and the humidity levels.
Is negative pressure in a home bad?

Proper ventilation keeps the air fresh and healthy indoors. Like the lungs, homes need to be able to breathe to make sure that fresh air comes in and dirty air goes out. Air indoors can build up high levels of moisture, odors, gases, dust, and other air pollutants.
What causes negative pressure in a building? Hot air rising.
Warm air in your building rises to the upper floors, and can result in negative air pressure in the lower areas. Also, combustion appliances like furnaces and large fireplaces draw hot air up and out of the building through vents, causing negative air pressure if they expel too much air out.
Is air pressure higher indoors than outdoors?
Usually there is the same pressure inside a building as outside because there are openings such as vents and windows which equalize the pressure.
How do I increase the positive pressure in my house?
There are three ways to provide this: an “exhaust-only” or “negative pressure” setup that blows air out of the house, pulling makeup air in through holes or cracks in the building envelope; a “supply-only” or positive pressure system that draws outdoor air in through a duct, forcing the indoor air to escape through …
Does negative air pressure cause headaches? Several studies have suggested that changes in weather, and especially changes in pressure, increase the likelihood of having a headache. Some people experience high-altitude headaches due to changes in barometric pressure, such as during plane travel.
How much does AC flush cost? It’s a simple procedure, but it can take a while to check everything out and ensure that there is no further damage, so expect to pay about $120 for the labor costs.
