What Newcastle sites throw at HVAC
Coastal corrosion on rooftop plant. Package units on exposed rooftops anywhere near the coast take a beating. Coil corrosion reduces capacity gradually, so the complaint is usually that it is not as cold as it used to be rather than a failure. Coil condition should be part of every service on a coastal site, not just when something breaks.
Mixed-age systems in older buildings. A lot of Newcastle commercial stock has been re-fitted several times, leaving buildings running two or three generations of equipment on controls that were never designed to talk to each other. Zones fight each other, some spaces never reach setpoint, and energy use climbs. Sorting the control strategy often achieves more than replacing the plant.
Kitchens and dining rooms on one system. A kitchen exhausting hard while the dining room is trying to hold temperature is a make-up air problem, not an air conditioning fault, and no amount of extra cooling capacity will fix it.
