Duct Replacement & Design

Maximum Comfort Through Precision Design

Most HVAC systems lose 20-30% of their heating and cooling due to poorly designed or aging ductwork. If you have "hot spots," noisy registers, or high energy bills, a total duct replacement with engineered layout design is often the solution. Working Class HVAC doesn't just swap flex duct; we perform Manual D calculations to ensure every branch duct is sized correctly for the static pressure of your unit.

Our Ductwork Engineering:

• Static Pressure optimization: Ensuring your blower fan doesn't work harder than it needs to.
• Custom Plenum Fabrication: Airtight connections at the heart of your system.
• Proper Branch Sizing: Delivering the exact CFM required for the square footage of each room.
• R-8 High-Efficiency Insulation: Maximizing thermal retention across long duct runs.
• Return Air Balance: Ensuring proper intake to prevent system "suffocation."
