Replacing ductwork is worth it when the ducts are failing, unsafe, or fundamentally wrong for the home, while targeted repairs make sense for isolated leaks or minor wear. The most common driver for replacement is widespread damage or contamination that cleaning or sealing cannot solve. If visible mold growth is present in rigid sheet-metal ducts, cleaning is recommended after fixing the moisture source; replacement is considered when the material or layout is too compromised to restore. A technician’s telltale sign: if dust returns soon after cleaning and filters load fast, there may be hidden breaches rather than just dirt. We handle inspections and duct projects across the Madison area.
Consider these decision signals:
- Replace: extensive rust or holes; crushed or undersized runs; persistent mold after moisture is fixed; severe comfort or airflow imbalance due to layout.
- Repair: a few leaking joints; loose connections; minor insulation or boot damage.
Schedule a professional duct inspection, including inaccessible sections, before deciding.

We don’t list a flat price for full ductwork replacement. Actual cost is confirmed after an on‑site inspection by a Harker technician. Pricing depends on home size, duct length and access, material (e.g., sheet metal), needed sealing/balancing, and any moisture or mold issues. Our Madison-area team uses specialized tools to inspect hidden sections and will show you any problems. If ducts are sound and no allergies or mold are present, replacement may be unnecessary; cleaning or IAQ upgrades could be enough. $500 off Mitsubishi ductless installs is available.

"My Harker furnace install team was great... I had duct work done, too, and they did a great job and cleaned up any mess created by the work." — Susan H.
Air duct replacement cost varies by home and is confirmed after an on-site inspection. Our technicians use specialized tools to inspect hard-to-see duct sections and show you any issues. Price depends on duct length and layout, material changes, access in attics or crawlspaces, and fixing any moisture or mold before work. If no allergies and no visible dust or mold, cleaning or no service may be appropriate instead of replacement. We serve Madison and nearby cities with integrated indoor air quality solutions.

"They kept me in the loop as things got done." — Susan H.
Air duct cleaning cost is confirmed after an in-home inspection. Our technicians use specialized tools to check inaccessible duct sections. Price depends on home size, number of ducts and registers, system complexity, and debris level. Costs may be higher if we find visible mold or moisture problems that must be resolved before cleaning. Our cleaning scope includes supply and return ducts, registers, grilles, diffusers, coils, condensate pans, fan motor and housing, and the air handler housing.

For better HVAC efficiency, start with a professional duct inspection. Our technicians use specialized tools to find leaks in hard‑to‑see areas and show you any problems. If mold is present, we first resolve the moisture source, then clean affected components before any follow‑up work. Madison‑area homeowners often bundle this with routine maintenance through our Goldstar program to prevent future issues and maintain airflow and filtration across seasons.
Quick checks:
- Schedule a duct inspection with specialized tools.
- Address moisture sources before any cleaning.
- Add IAQ upgrades (filtration, ventilation) if recommended.
