HVAC pressure is the amount of force generated by a heating or cooling system’s operation throughout a building. HVAC stands for heating venting and air conditioning. In order for a forced air unit to function the way it was intended to, the right amount of pressure must be generated between the air being pulled into the unit and the amount of air being forced out of the unit into the building.
In order to create the correct amount of HVAC pressure, there are a number of factors that must be taken into consideration. First, the size of the building the unit will be providing either heated or cooled air for must be calculated. This is necessary to determine the size of the forced air unit required to maintain a comfortable air temperature for the building.
Once the amount of space the unit will have to hear or cool is determined, the size and type of unit can be decided upon. In order to create enough HVAC pressure within the duct work used to feed temperature controlled air into the building, the unit has to have enough strength to easily push or force the air to the point of the building that is highest in the system. It must do this without becoming overworked.

Once the size of the unit has been determined, the size and design of the ducting that will be run through the building must be determined as well. The size of the ducting is imperative at this point, because ductwork that is too large will not allow the unit to efficiently push controlled air through it. The ductwork that feeds the unit its supply of fresh air must also be of the correct dimensions. If it isn’t, the air flow into the unit can become constricted, which can result in the unit becoming damaged.
The design of both the incoming and outgoing ductwork must be laid out in a manner that allows for the pressurized forcing of controlled air through the output ducts. It must also allow for the appropriate pulling of pressured air through the incoming ductwork to efficiently provide the amount of controlled air desired by the user. If this amount of HVAC pressure becomes varied in any way, the effectiveness of the unit may be compromised. The unit may even become damaged over the course of time because of improper HVAC pressure.
