How long does duct replacement take?

A full replacement typically requires two to three days. Partial replacements or less complex layouts can sometimes wrap up in a single day. We provide a timeline estimate during your initial consultation.

Can I replace just part of my ductwork?

Absolutely. When the majority of your duct system is sound but certain sections are damaged, disconnected, or undersized, we can target those areas specifically. We inspect the whole system first and recommend the most cost-effective path.

What type of ductwork do you install?

We work primarily with insulated sheet metal for main trunk lines — it is more durable and promotes better airflow — and insulated flex duct for branch runs in tighter spaces. The specific design is tailored to your home's layout and your system's airflow requirements.

Duct Replacement Pricing for WNC Homes

A full duct replacement in a typical Western North Carolina home falls between $3,000 and $8,000, influenced by square footage, number of zones, duct material choices, and accessibility. Partial duct work — targeting only the most compromised sections — generally runs $1,000 to $3,000. Ductwork is the frequently overlooked link between your HVAC equipment and every room in the house, and when it is leaky, crushed, disconnected, or undersized, even top-rated heating and cooling equipment cannot deliver the comfort you are paying for.

Signs It Is Time for New Ductwork

Most duct systems have a functional lifespan of 20 to 25 years before joints degrade, tape adhesive fails, insulation flattens, and flex duct begins to sag. Many older homes throughout Asheville and the WNC mountains still rely on original ductwork that has long outlived its usefulness — or ductwork that was undersized from the outset. Red flags that point to replacement include persistent hot and cold spots from room to room, excessive dust even with fresh filters, whistling or rattling duct noises, and utility bills that seem disproportionately high for your system's efficiency rating.

How We Approach Duct Replacement

Quality Mechanical designs every new duct layout with Manual D airflow calculations to guarantee proper sizing for your equipment. We strip out the old ductwork, install new insulated ducts with sealed joints at every connection point, and balance airflow to each room individually. Every joint is secured with mastic sealant and mechanical fasteners rather than duct tape, which breaks down within a few years. The end result is a distribution system that moves the right volume of conditioned air to every room while minimizing energy loss.

A Measurable Return on Investment

According to the Department of Energy, leaky ductwork accounts for 20 to 30 percent energy loss in a typical residence. Replacing old, leaking ducts can cut your heating and cooling expenses by that same percentage — often saving $300 to $600 annually in WNC. Pair new ductwork with a high-efficiency HVAC system and you unlock the greatest possible return on your comfort investment.
