Ductwork & airflow design

Understand the cause and the scope

We look at the existing air-distribution layout, accessible condition, and the comfort concerns you describe. Return pathways, supply runs, transitions, and insulation can affect the result. Air-distribution redesign by a mechanical engineer is available as part of a defined project scope.

Make a confident decision

A proposal should identify which ducts are replaced, altered, or reused. Ask how the recommendation relates to the home’s load and equipment. Existing conditions and the scope you approve affect the final result.

Built for Gulf Coast conditions

Southwest Louisiana systems work through long cooling seasons, high humidity, salt-influenced air, storms and heavy rainfall. The recommendation should consider drainage, corrosion exposure, airflow and recovery after outages—not equipment capacity alone.

Equipment and registration

S&S is a Carrier - Tempstar Elite Dealer and an approved Trane Dealer. Ask which brand and model fit the project. Manufacturer registration controls eligibility for extended parts coverage. S&S submits registration where possible; the customer should retain and check the manufacturer confirmation. The manufacturer’s written eligibility and warranty terms control.

Parts coverage and workmanship coverage

Manufacturer parts coverage and S&S workmanship coverage are separate. A manufacturer parts warranty covers the part only; diagnostic labor, refrigerant, freight and miscellaneous materials are billable unless covered under the S&S labor warranty. Standard S&S coverage is one year on installation workmanship and 90 days on repairs, unless a longer period is stated in writing on the estimate or purchased as an extended labor plan. Covered workmanship corrections include labor during normal business hours. Maintenance requirements, exclusions and other written conditions apply.

Map the comfort pattern before changing the ducts

Make a room list and record which spaces are uncomfortable, when it happens, and whether doors are open or closed. Add any remodeling, insulation, window, or equipment changes that preceded the concern. This creates a useful starting point for comparing the reported problem with the air-distribution layout.

ENERGY STAR’s professional duct guidance includes evaluating supply and return balance, identifying damaged runs, and assessing airflow after improvements. Ask which inspection or measurements are appropriate for the problem and what finding supports each proposed change.

Know whether the project is repair, sealing, insulation, or redesign

A disconnected run, a damaged insulation layer, a leakage problem, and an unsuitable layout call for different work. Have the estimate distinguish the areas being repaired, altered, sealed, insulated, replaced, or reused. That prevents a broad “ductwork” line from hiding important differences between proposals.

ENERGY STAR notes that leakage and poor connections can waste conditioned air and contribute to uncomfortable rooms. If a replacement system is also planned, discuss the ducts at the same time so retained components and equipment selection are considered together.

Make the result assessable

Before approving the project, ask how the completed work will be evaluated and what limitations remain in unaltered areas. Document the original comfort concerns alongside the approved scope so the final discussion returns to the problem you wanted solved.

Ask how the work preserves filter access, equipment service access, and the intended use of the space. An engineering approach should make the reasoning and scope understandable; it is not a substitute for identifying the actual existing conditions.

• Observed room pattern and relevant findings
• Exact runs and components changed or retained
• Post-work assessment included in the scope
• Known access limits and unresolved conditions
