The answer to 'how often to replace tune-up' is that most HVAC experts recommend getting a professional tune-up for your heating and cooling system once a year. This annual maintenance helps ensure your system is running efficiently and can catch any minor issues before they become major problems.
During a tune-up, an HVAC technician will thoroughly inspect your system, clean and lubricate moving parts, check refrigerant levels, and make any necessary adjustments. This helps extend the lifespan of your HVAC equipment and can improve its energy efficiency, potentially saving you money on your utility bills.
