The answer to 'when to service maintenance' is that HVAC systems should be serviced and maintained regularly, typically once or twice a year. Regular maintenance helps ensure the system is running efficiently, extends the lifespan of the equipment, and prevents costly breakdowns.
It's recommended to have your HVAC system serviced in the spring before the cooling season and in the fall before the heating season. This allows a technician to inspect the system, clean components, check refrigerant levels, and make any necessary adjustments or repairs. Homeowners should also change air filters every 1-3 months to keep the system running smoothly.
