Arzels first app for iPad makes HVAC zoning system design simple and quick! The app helps contractors select the right Arzel product for residential applications and generates a bill of materials based upon selected equipment details, duct work sizing and access to runs. An estimated labor time is given for each part and can be adjusted by the contractor based on application specifications. EzyZone gives the contractor a comfort plan that can be shared with a homeowner customer displaying the number of zones suggested and a quote for the system and labor.
