What is a common symptom of a refrigerant overcharge?

A common symptom of refrigerant overcharge is high head pressure and potential compressor failure. When a system is overcharged with refrigerant, the amount of refrigerant exceeds the manufacturer's specifications, which leads to excessive pressure within the system.

This high pressure can cause the compressor to work much harder than it is designed to, ultimately leading to overheating and failure over time. The compressor is responsible for compressing the refrigerant and circulating it through the system, and when the pressures are too high, it may not operate efficiently, which can create additional strain on the components.

In contrast, low head pressure and system freeze-up is generally associated with undercharging or other issues in the system, not an overcharge. Increased noise levels might indicate other issues like mechanical problems or airflow restrictions but are not definitive symptoms of an overcharged system. Frequent cycling of the compressor can occur for various reasons, including improper charge levels, but it is not specifically indicative of refrigerant overcharge.
