Chill with Confidence: Ace the 2026 ASE Air Conditioner Exam and Keep Cool Under the Hood!

Overcharging an A/C system can lead to increased pressure, which can cause various components within the system to experience stress and potential failure. When the refrigerant levels are too high, the compressor has to work harder to manage the excess refrigerant, which can result in overheating and eventual breakdown of the compressor or other components. Additionally, the imbalanced pressure can impair the system's ability to adequately cool the cabin, leading to decreased cooling efficiency. Maintaining the correct refrigerant charge is crucial for optimal performance and longevity of the A/C system.
