The answer to 'when to service AC' is that you should have your air conditioning system serviced at least once a year, ideally in the spring before the hot summer months. Regular maintenance is essential to ensure your AC unit is running efficiently and to prevent costly breakdowns.
During a routine service, an HVAC technician will inspect the system, clean the coils, check refrigerant levels, and perform any necessary tune-ups or repairs. This helps extend the lifespan of your AC unit and keeps it operating at peak performance.
