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.
If your system is over 10-15 years old, requires frequent repairs, or struggles to maintain consistent temperatures, it may be time for a replacement. Our team can assess your unit and recommend the most cost-effective solution.

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.
