What is a common result of overcharging an HVAC system?

Overcharging an HVAC system typically results in high pressure readings. When an HVAC system is overcharged with refrigerant, it increases the pressure of the refrigerant within the system. This elevated pressure can lead to a variety of operational issues, such as inefficient cooling and potential damage to the system components. High pressure can also cause the compressor to work harder than necessary, increasing the risk of overheating and failure.

In contrast, options like increased cooling efficiency, lower energy costs, and enhanced airflow do not occur as a result of overcharging. In fact, overcharging compromises the overall efficiency and can lead to higher energy costs instead. Enhanced airflow may not be affected directly but can also suffer from the inefficiencies caused by high pressure in the system. Understanding the relationship between refrigerant levels and system performance is crucial in HVAC maintenance and operation.
