Plandroid

Plandroid is a simple and efficient graphical software tool for ducted air conditioning / HVAC system design and quoting. It allows you to create a CAD-style ducting design superimposed over a house plan image, using components from your hardware supplier's actual parts catalog. Plandroid calculates basic heat loads, does a costing of your design, and creates reports for your customer, installer, or supplier. The graphical design process is simple and intuitive - vastly simpler than traditional CAD, and with much clearer results.
