HVAC Duct Design & Engineering Services
Low-static, acoustically engineered ductwork designed to deliver balanced air distribution across every zone in your building.
Professional HVAC Duct Design Solutions
Ductwork is the circulatory system of any HVAC installation, and its design directly determines air quality, noise levels, and energy consumption. Poorly routed ducts create uneven temperature distribution, excessive static pressure, and noise complaints that are difficult and expensive to fix after installation.
Yasmin Airconditioning Pvt.Ltd. approaches duct design using the Equal Friction method and velocity-based sizing to ensure air reaches every diffuser at the correct flow rate and pressure. Our engineers coordinate with structural and architectural drawings to route ducts in available ceiling space without compromising headroom or aesthetics.
Every duct design we produce includes acoustic attenuation calculations, static pressure loss analysis, and balancing damper schedules, so your system is balanced from the first day of commissioning without extended site adjustment.
What's Included in Our Duct Design Service
Duct Sizing & Layout
Equal friction and velocity-based duct sizing to maintain correct CFM delivery to every branch and diffuser.
Static Pressure Calculation
Total system static pressure analysis to correctly select AHU fan performance and motor sizing.
Acoustic Attenuation
Sound power level calculations and silencer/liner specifications to meet noise criteria for each space type.
Balancing Damper Schedule
Volume control damper placement and pre-set positions to achieve designed airflow balancing at commissioning.
Insulation Specification
Thermal and acoustic insulation schedules for ducts in unconditioned spaces, cold surfaces, and plant rooms.
Coordinated Shop Drawings
Duct routing drawings coordinated with structural, piping, and electrical to avoid clashes before fabrication.
Benefits of Professional Duct Design
The right HVAC engineering partner delivers measurable improvements across every dimension of your project, from construction efficiency to long-term operational cost.
Silent Operation
Correct velocity and acoustic attenuation eliminate duct noise, a common complaint in poorly designed systems.
Balanced Air Distribution
Every diffuser receives its designed CFM, maintaining consistent temperature across all zones and floors.
Energy Efficiency
Low-static duct layouts reduce fan energy consumption and allow smaller, quieter fan selections.
Faster Installation
Coordinated duct drawings with clash detection reduce on-site rework and shorten mechanical installation time.
Code Compliance
Duct design meeting SMACNA standards and NBC requirements satisfies inspectors and MEP sign-off.
Low Maintenance
Properly sized ducts with correct velocities resist dust accumulation and simplify future cleaning access.

Frequently asked questions
What is HVAC duct design?
HVAC duct design is the engineering process of sizing and routing air distribution ducts to deliver the correct volume of conditioned air to every space in a building at the right pressure, velocity, and noise level.
What is the Equal Friction method in duct design?
The Equal Friction method sizes each duct section to maintain a constant pressure drop per unit length. This approach balances the system naturally and is widely used for commercial HVAC systems to ensure consistent air delivery.
How does duct design affect energy consumption?
Oversized ducts waste material and space; undersized ducts create high static pressure that forces fans to work harder, consuming more energy. Optimised duct design minimises system resistance and fan motor energy.
Can you design ducts for an existing building?
Yes. Yasmin Airconditioning Pvt.Ltd. has extensive experience designing replacement duct systems for retrofit and renovation projects, working within constrained ceiling voids and existing structural constraints.
What drawings are produced as part of a duct design?
We produce duct layout drawings at floor plan level, duct sections showing heights and dimensions, a static pressure calculation report, a diffuser/grille schedule, a balancing damper schedule, and an insulation specification.
Do you coordinate duct drawings with other trades?
Yes. All our duct drawings are coordinated with structural beams, fire sprinkler lines, electrical cable trays, and plumbing to avoid clashes before any fabrication begins.
