1. A method for measuring a Heating, Ventilating, Air Conditioning (HVAC) system airflow, the HVAC system having an air register and a plenum, a duct or a box in fluid communication with the air register, wherein the box is configured to be reversibly engaged with the air register, the method comprising:
drilling a single access hole in a near side of the plenum, the duct, or the box;
inserting a hot-wire anemometer probe into the single access hole;
positioning the hot-wire anemometer probe at a near side location disposed between the near side and a depth centerline of the plenum, the duct, or the box and taking a first airflow measurement while the hot-wire anemometer probe is in the single hole;
positioning the hot-wire anemometer probe at a depth centerline location disposed on the depth centerline approximately halfway between the near side and afar side of the plenum, the duct, or the box and taking a second airflow measurement while the hot-wire anemometer probe is in the single hole;
positioning the hot-wire anemometer probe at a far side location disposed between the depth centerline and the far side of the plenum, the duct, or the box and taking a third airflow measurement while the hot-wire anemometer probe is in the single hole; and
calculating an average HVAC system airflow based on the first airflow measurement, the second airflow measurement, and the third airflow measurement.
