An air conditioning unit may be overcharged with refrigerant due to a variety of reasons, such as inexperienced technicians not properly measuring the refrigerant levels, miscommunication between service providers and homeowners, or a lack of understanding of the system's specifications. Additionally, some individuals may mistakenly believe that adding more refrigerant will improve the unit's cooling performance, leading to overcharging.

When it comes to AC systems, costs simply mean more repairs than replacements. Finding the right repair company to work with you means saving thousands of dollars on costly replacements when your older system may be running just fine with a few repairs.
