The answer to 'when to service AC repair' is that your air conditioning system should be serviced annually, ideally before the start of the cooling season. Regular maintenance helps ensure your AC unit is running efficiently and can catch any potential issues before they become major problems.
During an AC tune-up, a technician will thoroughly inspect the system, clean the coils, check refrigerant levels, test electrical components, and make any necessary adjustments or minor repairs. This helps extend the lifespan of your AC unit and can also improve its cooling performance and energy efficiency, saving you money on your utility bills.
