Blizzard Wizard stocks a wide variety of electric and hydronic make up air systems. and custom builds make up air units for all different kinds of applications. By building make up air units to suit individual client needs we are able to determine what size and type of make up air unit will be most practical for your application. Depending whether or not you have hot water heating in your building we can determine whether it will be a hydronic or electric make up air. Sizing a make up air volume is largely dependent on the municipal jurisdictions and building codes in your area. Blizzard Wizard closely inspects these parameters and constructs the make up air unit to operate based on these conditions.
