How often should my HVAC be serviced?

HVAC systems should generally be serviced by a professional technician at least once a year, preferably before the start of the heating or cooling season. Regular maintenance can help identify and address potential issues before they become major problems and can also help ensure that the system operates efficiently and effectively. Some systems may require more frequent maintenance depending on factors such as the age of the system, the level of use, and any specific manufacturer recommendations.
