HVAC Products

Sterling manufactures gas-fired, oil-fired, hot water, and steam unit heaters. Their gas-fired propeller heaters can fit in large open areas, while blower units and duct furnaces discharge from the ventilation area. Sterling's oil-fired heaters work with number-two heating oil fuel, and their hot-water units connect to central boiler systems. HVAC technicians can apply Sterling heaters for both commercial and industrial use.
