Putting a Number on Your Duct Leakage
Duct leak testing uses calibrated equipment to measure the actual air leakage rate of your duct system. A duct blaster (a specialized fan and pressure gauge) pressurizes your ductwork and measures how much air escapes through leaks. The result is expressed in CFM (cubic feet per minute) of leakage at a standard test pressure. This gives you a clear, objective measurement — not a guess — of how much energy your ducts are wasting.
When Duct Testing Makes Sense
Duct leak testing is valuable in several situations: you suspect leaky ducts are causing comfort problems or high bills, you're planning duct sealing and want before-and-after measurements, you're adding a new system and want to verify duct integrity before investing in equipment, or your home is being evaluated for energy efficiency improvements. In Western North Carolina, where many homes have ducts running through unconditioned attics and crawl spaces, duct leakage is a major contributor to energy waste.
What the Numbers Mean
A well-sealed duct system leaks less than 4% of total airflow. Many existing homes in WNC have duct leakage rates of 15-30% or more — especially homes with older flex duct or original ductwork from the 1970s-1990s. After testing, we provide a detailed report showing your leakage rate and recommendations for improvement, whether that's targeted sealing, duct repair, or partial replacement.
HVAC Challenges in Mars Hill
Mars Hill's elevation and northern Madison County location make it one of the colder spots in our service area. The university campus and surrounding rental properties create concentrated HVAC service demand during the academic year. Many rural homes in the Spring Creek and Gabriels Creek valleys rely on propane or oil heating and lack natural gas access, requiring specialized fuel system knowledge.
Seasonal Tip for Mars Hill Homeowners
Mars Hill-area homes with propane furnaces should schedule fuel delivery and furnace inspection together in early fall. Running out of propane on a cold night is an emergency we see too often — set up automatic delivery if your provider offers it, and keep your furnace well-maintained to maximize fuel efficiency.
