Four kinds of HVAC on one service board
Bayside and Whitestone are detached single-family territory: full ducted systems, outdoor condensers on side yards, and attic or basement air handlers that make replacement work straightforward and profitable. Forest Hills mixes prewar co-op apartments running on building steam with Tudor homes on hydronic heat. Astoria and Ridgewood are attached and semi-attached housing dominated by ductless heads, through-wall sleeves, and rooftop condensers. Flushing adds converted multi-family buildings and small commercial storefronts with packaged rooftop units.
Each of those requires a different truck stock and a different skill set. Dispatching a residential ducted technician to a storefront RTU on a Flushing roof burns the appointment, and the customer books somebody else that afternoon.
