None of those scenarios result in happy customers after they’ve paid big bucks for a new, more efficient HVAC system or upgraded ductwork. Incorrect duct size can also cause inadequate airflow to certain areas and produce unwelcome noise. Using the wrong size duct for the space can prematurely wear out HVAC components and will likely increase customers’ energy expenses. To check for accurate measurements, many techs rely on HVAC duct sizing calculator free tools, such as a ductulator. Too large or too small HVAC ductwork sizing can cause problems similar to what happens when technicians install an improperly sized HVAC unit.
