The "top" refrigerant gas maintenance task is monitoring levels and checking for leaks, as refrigerant should not be "topped up" in a healthy, closed system. If a system requires a top-up, it indicates a leak that must be professionally located and repaired first.

Inspection is a proactive, professional check-up that involves systematically inspecting, cleaning, and servicing heating, ventilation, and air conditioning components to ensure safety, efficiency, and longevity, catching small issues (like dirty coils, low refrigerant, loose wiring, or clogged drains) before they become costly breakdowns, often done seasonally to keep systems running smoothly and maintain air quality.
