The answer to 'when to service air conditioner' is to have your air conditioning unit serviced annually, typically at the start of the cooling season. Regular maintenance is essential to ensure your AC system is operating efficiently and to catch any potential issues before they become major problems.
During an annual tune-up, an HVAC technician will clean the unit, check for proper refrigerant levels, test electrical components, and make any necessary adjustments or minor repairs. This helps extend the lifespan of your air conditioner and can also improve its cooling performance and energy efficiency, saving you money on utility bills.
