The answer to 'how long does tune-up last' is that a typical HVAC tune-up will last for about 1 year. HVAC systems require regular maintenance to operate efficiently and reliably, and an annual tune-up is recommended by most manufacturers and industry experts.
During an HVAC tune-up, a professional technician will inspect, clean, and adjust various components of the system to ensure it is running at its best. This can include tasks like checking refrigerant levels, cleaning the coils, lubricating moving parts, and testing for any issues. By performing this maintenance annually, you can help extend the lifespan of your HVAC system and avoid more costly repairs down the road.
