How Often IsHVAC Maintenance Needed?
Learn about the optimal maintenance schedule for your HVAC system to ensure peak performance and avoid costly breakdowns. Most systems require maintenance twice yearly, but frequency depends on several key factors.
Most HVAC Systems Need Service Twice Per Year
Professional maintenance should occur twice annually: once in spring (April-May) before cooling season and once in fall (September-October) before heating season. This bi-annual schedule can prevent 95% of system failures and maintain peak efficiency.
