That Ductless Mini Split Requires Occasional Maintenance — What That Involves

That Ductless Mini Split Requires Occasional Maintenance — What That Involves

Ductless mini-splits are gaining popularity in the United States, including here in the Metro-East area. Many people are drawn to the less expensive installation as compared to traditional HVAC systems; others are drawn to the energy efficiency of ductless mini splits, but one of the best perks of these alternatives to the traditional HVAC systems is the minimal amount of maintenance they require.

Ductless Mini Split Maintenance

Though the maintenance your ductless mini-split requires is minimal, it’s still just as important to perform these tasks on a regular basis in order to keep your system working at its best for years to come. Simply follow these steps to ductless mini-split maintenance:

  • Know how often to clean or change the air filters. Some units will only require annual cleaning of the filters, while others may require as often as monthly cleaning, depending on usage and other factors. Be sure to clean or change the filters according to the manufacturer’s recommendation, or more often if the environment requires.
  • Your ductless mini-split likely has indoor air quality components. Be sure to remove and clean these per manufacturer instructions.
  • Monitor your evaporator coils and clean as necessary. Though these coils are well protected in the indoor air handling unit, it’s still a good idea to inspect them once a year and clean them as needed.
  • Your ductless mini-split has a fan wheel and blower assembly. Inspect these annually, adjusting the balance as required (if you know how).
  • It is a good idea to annually inspect the outside condensing unit. Check to make sure there’s no deterioration in the insulation, that the refrigerant lines are undamaged, and that the unit is still well mounted.
  • Make sure the outside unit is free of debris, with no weeds, grass or plants growing around it, that no small animals have set up home in or around it, and that it seems to be operating correctly.
