When it comes to cooling in Asheville, the local conditions matter. 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. Our AC technicians understand these Asheville-specific factors and size every repair and recommendation accordingly.

When Flex Duct Becomes the Problem

Flexible ductwork (flex duct) is common in WNC homes because it's affordable and easy to route through tight spaces. But flex duct has a limited lifespan and is frequently installed poorly — sagging, kinked, stretched too tight, run in overly long lengths, or crushed by stored items in the attic. Damaged or poorly routed flex duct restricts airflow, forcing your system to work harder, increasing energy costs, and reducing comfort in the rooms served by those runs.

Signs Your Flex Duct Needs Attention

If certain rooms have weak airflow from the registers, if your attic ductwork looks like a tangled mess of sagging silver tubes, or if you can see torn outer jackets exposing the insulation, your flex duct is hurting your system's performance. Even duct that looks intact may have an inner liner that has separated from the outer insulation, creating a hidden restriction. Our technicians inspect ductwork visually and measure airflow at each register to identify problem runs.

Proper Replacement Restores Performance

When we replace flex duct, we follow ACCA and manufacturer best practices: runs are kept as short and straight as possible, properly supported every 4-5 feet, connected with mechanical fasteners and sealed with mastic, and sized correctly for the airflow each room requires. The difference in airflow after replacing crushed or poorly installed flex duct is often dramatic. This service pairs well with duct sealing and duct balancing for a complete duct system restoration.
