The answer to when to service an HVAC system is that it should be serviced at least once a year, preferably in the spring before the cooling season begins or in the fall before the heating season. Regular maintenance is essential to ensure your HVAC system is running efficiently and to prevent costly breakdowns.
During an HVAC tune-up, a technician will clean and inspect the system, check for any wear and tear, and make any necessary adjustments or minor repairs. This helps extend the lifespan of your HVAC equipment and can improve its energy efficiency, saving you money on utility bills.
