Regular servicing of an AC system is essential to ensure optimal performance and longevity. It is generally recommended to have your AC system serviced at least once a year. The ideal time for this maintenance is typically in the spring, before the cooling season begins.  Depending on your usage and environmental factors, you may consider more frequent servicing. For instance, if you live in a region with hot and humid summers, or if you use your AC system extensively, bi-annual servicing may be beneficial. Regular servicing includes tasks such as cleaning or replacing air filters, inspecting and cleaning coils, checking refrigerant levels, lubricating moving parts, and examining electrical connections.  These services help improve energy efficiency, prevent breakdowns, and extend the lifespan of your AC system. It’s worth noting that some manufacturers may also specify recommended service intervals for their specific models, so it’s a good idea to consult the manufacturer’s guidelines or consult with a professional HVAC technician for personalized recommendations.
