This ensures optimal performance and avoids short-circuiting or other electrical issues. Proper drying time also helps maintain the efficiency and longevity of your air conditioning unit. Always refer to your HVAC specialist’s advice for specific recommendations based on your system. Keep your AC running smoothly by following these best practices after coil maintenance!
