Franklin's location in the Little Tennessee River valley creates a moderate mountain climate, but the distance from major service centers means many homes go longer between HVAC maintenance visits. Macon County's mix of year-round residents and seasonal mountain homeowners creates varied demands — some systems sit idle for months, then must perform immediately. Natural gas availability is limited outside the town core, making propane and heat pump expertise essential.

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.
