Ducting Design, HVAC System Layouts, AstraCAD UK Services

Efficient and well-designed duct systems distribute air properly throughout your home without leaking to keep all rooms at a comfortable temperature. The system should provide balanced supply and return flow to maintain a neutral pressure within the house.

AstraCAD provides 3D drawings in DWG format for ducting design. 3D allows visualisation and optimal design solution around obstructions etc. We can also size the system to match flow rates required. Material lists can also be provided for you.
