The answer to 'how often to replace inspection' is that most HVAC experts recommend having your system inspected and serviced at least once a year, typically in the spring or fall before the peak heating or cooling seasons. Regular inspections help ensure your HVAC system is running efficiently and catch any potential issues before they become major problems.
During an HVAC inspection, a certified technician will thoroughly check all components of your system, including the air filters, refrigerant levels, electrical connections, and more. They can identify any worn or damaged parts and recommend necessary repairs or replacements to keep your system in optimal condition.
