DUCT-FREE SPLIT SYSTEMS
Regular maintenance helps prolong your system’s lifespan and ensure that it functions with maximum energy efficiency. Contact your Carrier dealer for maintenance services or tips.
Here are some simple things you can do to keep your system functioning properly:

  • Keep your Indoor unit clean: vacuum off any dust, wipe it down with warm water and then use a soft cloth to dry it.
  • Clean your air filters every two weeks, with either a vacuum or a mild detergent and warm water. Let your filter air dry completely before reinstalling it. 
  • Carbon filters should be changed every three months.
  • Remove dirt and debris from the exterior coil with a garden hose.

Caution: Always switch OFF and disconnect your AC before cleaning it.
