We recommend seasonal maintenance (pre and postseason) if you have a cooler fitted with a bleed system, including regular servicing of your evaporative air conditioner. If your evaporative cooler is fitted with a drain valve, no seasonal maintenance is required, but maintenance checks are essential to ensure the cooler operates efficiently for many years.
