The answer to 'what is tune-up' is a routine maintenance service for HVAC (heating, ventilation, and air conditioning) systems. An HVAC tune-up involves a comprehensive inspection, cleaning, and adjustment of the system's key components to ensure optimal performance, energy efficiency, and longevity.
During a tune-up, an HVAC technician will typically check and clean the air filters, inspect the condenser coils, lubricate moving parts, test the thermostat, and make any necessary adjustments to the system. This helps to improve airflow, reduce energy consumption, and prevent potential issues before they become major problems.
