Regular HVAC maintenance should be performed twice a year—once before the cooling season (spring) and once before the heating season (fall). This ensures optimal performance, energy efficiency, and fewer unexpected breakdowns.

For standard filters, replacement is recommended every 1-3 months. High-efficiency filters may last longer, but regular checks ensure better air quality and system efficiency.
