A: It’s generally recommended to have your HVAC system serviced at least once a year, ideally during spring for cooling systems and fall for heating systems. This ensures your system is prepared for the upcoming season and functioning efficiently. However, some factors, such as the age of your system or the presence of allergies, may require more frequent servicing. Consult with a professional HVAC company like Country Cooling and Heating LLC to determine the best maintenance schedule for your specific needs.
