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, typically in the spring or fall before the peak seasons. A tune-up helps ensure your system is running efficiently and can identify any potential issues before they become major problems.
During a tune-up, an HVAC technician will thoroughly inspect your system, clean components, check refrigerant levels, test safety controls, and make any necessary adjustments or minor repairs. This helps extend the lifespan of your HVAC equipment and can improve its performance, saving you money on utility bills and avoiding costly breakdowns.
