What is a potential consequence of improper refrigerant charge in an AC system?

Improper refrigerant charge in an AC system can lead to reduced cooling efficiency. When the system is overcharged or undercharged with refrigerant, it disrupts the optimal heat exchange process that is essential for effective cooling. An overcharge can result in increased pressure within the system, causing the compressor to work harder than necessary, while an undercharge leads to insufficient refrigerant to absorb and remove heat. Both scenarios impair the system's ability to cool effectively, leading to discomfort and increased energy consumption as the system struggles to maintain the desired temperature. This inefficiency often results in a higher operating cost and can ultimately shorten the lifespan of the AC system.
