Hard Numbers Instead of Guesswork
Duct leak testing uses calibrated instruments to measure your duct system's actual leakage rate. A duct blaster — a specialized fan paired with a precision pressure gauge — pressurizes the ductwork and records how much air escapes. The result is expressed in CFM (cubic feet per minute) of leakage at a standardized test pressure, giving you a clear, objective figure rather than a rough guess about how much energy your ducts waste.
Situations Where Testing Pays Off
Duct leak testing adds value whenever you suspect leaky ducts are behind comfort issues or inflated bills, when you plan duct sealing and want verified before-and-after data, when you are investing in new equipment and want to confirm duct integrity first, or when your home is undergoing an energy efficiency evaluation. Across Western North Carolina, where countless homes run ducts through unconditioned attics and crawl spaces, duct leakage is a leading source of wasted energy.
Interpreting the Results
A tightly sealed duct system leaks less than 4 percent of total airflow. Many existing WNC homes register leakage rates of 15 to 30 percent or higher — particularly those with aging flex duct or original ductwork dating to the 1970s through 1990s. Following the test, we deliver a detailed report with your measured leakage rate and targeted recommendations, whether that means sealing, duct repair, or partial replacement.
HVAC Challenges in Asheville
Asheville's mix of historic homes in Montford and North Asheville — many built before central HVAC existed — creates unique retrofit challenges. These older homes often have limited ductwork space, uneven heating across floors, and single-pane windows that strain heating systems. Meanwhile, newer South Asheville construction demands properly sized high-efficiency systems to handle the area's 4,400+ heating degree days per year.
Seasonal Tip for Asheville Homeowners
Asheville's elevation means nighttime temperatures can drop into the 20s even in early spring. We recommend keeping your heating system serviced through April and scheduling AC maintenance by mid-May to prepare for the humidity that builds through summer.
