Drain Pan
A drain pan is an essential component in air conditioning and heating systems that collects water produced during normal operation. When air conditioners cool warm air, they create water through condensation (like water droplets on a cold drink). This water needs to be safely collected and removed to prevent damage to buildings. Think of it like a safety tray that catches drips. HVAC technicians need to regularly check, clean, and sometimes replace drain pans to prevent water damage and mold growth. You might also see it called a "condensate pan" or "drip pan" in job descriptions and resumes.
