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 Marion

At just 1,437 feet, Marion sits at one of the lowest elevations in our service area — meaning hotter summers and higher cooling demands than mountain communities to the west. The Catawba Valley funnels warm air from the piedmont, and Marion homes typically need 15–20% more cooling capacity than comparable Asheville homes. However, milder winters mean heat pump systems perform exceptionally well here year-round.

Seasonal Tip for Marion Homeowners

Marion's lower elevation means summer arrives 2–3 weeks earlier than in Asheville. Schedule your AC maintenance in early April to beat the rush, and consider upgrading to a higher-SEER unit if you're replacing — the longer cooling season means energy savings add up faster here.
