There are situations where duct repair isn't enough when the existing system was never properly designed, when flexible duct has degraded past the point of reliable repair, when a home addition requires a new branch design, or when asbestos-containing duct insulation makes restoration work hazardous. HVAC Pros. provides complete duct replacement in Campbellsport, WI using Manual D duct system design principles, which determine correct trunk and branch sizes based on the HVAC system's airflow requirements and the friction loss characteristics of each run. Undersized ducts create high static pressure that stresses blower motors and reduces airflow; oversized ducts reduce velocity enough that air stratifies before reaching the register. Proper design is what makes the difference between a duct system that works and one that creates complaints for years.
We install sheet metal trunk lines with sealed connections for durability and long-term airtightness, and use insulated flexible duct for branch runs where appropriate with proper support spacing to prevent sagging and flow restriction. All new ductwork installed by HVAC Pros. in Campbellsport, WI is sealed with mastic at every connection and insulated to current IECC requirements for its installation location. We perform post-installation duct leakage testing to verify performance before closing walls or attic access. In homes with older fiberglass duct board systems that have become brittle, developed mold growth, or suffered pest intrusion, full replacement is often the most cost-effective path to a clean, efficient distribution system. HVAC Pros. handles permits where required and coordinates inspections so your new duct system meets local mechanical code.
