HVAC Design — Manual J, D & S

Residential HVAC design

HVAC Design Manual J, D & S

Tacoma Energy provides coordinated residential HVAC design based on the home's plans, enclosure specifications, climate, and expected performance. Our team connects load calculations, duct design, and equipment selection so the final system is appropriately sized, documented, and ready for field implementation.

Load calculations

Manual J

Room-by-room heating and cooling loads based on the home's actual construction details, orientation, windows, insulation, air leakage, and local design conditions.

Duct design

Manual D

Duct sizing and distribution planning designed around the calculated airflow requirements, equipment, layout, and available construction space.

Equipment selection

Manual S

Equipment selection matched to the calculated loads and operating conditions to support comfort, efficiency, and dependable system performance.

One coordinated design package. Load calculations, duct requirements, equipment selection, and project documentation are developed together—not as disconnected reports.

Our Design Process

Each project begins with a review of the plans and performance inputs that directly affect HVAC sizing and distribution.

✓

Plans and project inputs reviewed Floor plans, elevations, window data, enclosure specifications, ventilation, and project requirements are evaluated.

✓

Calculations and layouts coordinated Manual J, D, and S deliverables are developed using aligned assumptions and documented design inputs.

✓

Final design package issued Completed reports and drawings are organized for the builder, HVAC contractor, permitting team, and field personnel.

Pricing & Turnaround

Pricing and turnaround are based on project size, system count, complexity, required deliverables, and available plan information. Tacoma Energy provides clear scope and pricing before work begins.

Basements, crawl spaces, multiple systems, revisions, and jurisdiction-specific requirements are reviewed as part of the project scope.
