A dimly lit industrial interior with various HVAC components prominently featured. In the foreground, a large commercial-grade air conditioning unit emits a low, rumbling hum. Nearby, a central furnace vibrates gently, its metal casing radiating a subtle heat. In the middle ground, a network of ducts and vents snakes across the ceiling, their metal surfaces reflecting the ambient lighting. In the background, a large industrial fan spins steadily, its blades cutting through the air with a soft, whooshing sound. The overall atmosphere is one of functional machinery, with the various noise sources blending together to create a layered, mechanical ambiance.
