Repair small-diameter high-velocity duct systems found in older homes and historic properties.
What Static Pressure Numbers Actually Tell Us
Static pressure is the resistance to airflow inside the duct system, measured in inches of water column, and it is one of the most useful diagnostic numbers in HVAC because it reflects the combined effect of every restriction in the system, the filter, the coil, the duct sizing, and any kinks or undersized sections, in a single measurement taken at the equipment. Most residential systems are designed to operate within a total external static pressure range of roughly 0.5 to 0.8 inches of water column, and readings meaningfully above that range indicate the blower is working harder than it should to move the same amount of air, which reduces both comfort and equipment life over time.
We test static pressure using a manometer connected to small probe holes drilled into the supply and return plenums near the equipment, taking separate readings on the supply side, the return side, and across the filter and coil individually where access allows. Reading these individually rather than just a single total number is important diagnostically, since a high reading isolated to the return side points toward undersized return ductwork or a dirty filter, while a high reading on the supply side points toward duct restriction, kinks, or undersized branch takeoffs further downstream. We also test airflow at the blower using the equipment's fan chart in combination with the pressure reading, since static pressure alone does not tell you actual cubic feet per minute without cross-referencing the specific blower's performance data.
Static pressure testing is the diagnostic step behind most of our other duct services, since it is how we confirm whether a suspected leak, an undersized return, or a kinked branch is actually causing a measurable problem versus a cosmetic issue with no real performance impact. In Georgetown, we recommend static pressure testing whenever a homeowner reports reduced airflow, unusually short or long system cycles, or after any duct modification project to verify the change achieved its intended effect. A standalone static pressure test typically takes 30 to 45 minutes and runs 100 to 200 dollars, though it is frequently included as part of a broader duct diagnostic or balancing visit rather than billed separately.
