The answer to 'when to service HVAC repair' is that HVAC systems should be serviced at least once a year, typically in the spring or fall before the peak heating or cooling seasons. Regular maintenance helps ensure your HVAC system is operating efficiently and can identify any potential issues before they become major problems.
During an HVAC service visit, a technician will inspect the system, clean or replace air filters, check refrigerant levels, test electrical components, and perform other maintenance tasks. This helps extend the lifespan of your HVAC equipment and can improve indoor air quality. Homeowners should also clean or replace air filters every 1-3 months to keep the system running smoothly.
