Your Ductless Mini Split Needs Routine Maintenance, Too

A ductless mini split is an energy-efficient choice in homes where installing or extending central A/C ductwork isn’t an economical option. The system combines the best of a central heat pump air conditioner with an individual room unit. A compact indoor air handler, usually mounted on the wall or ceiling, incorporates a coil and blower fan and is linked to an outdoor condenser/compressor unit by a conduit that conveys refrigerant between the two components. Because there are none of the energy losses associated with ductwork, ductless systems offer high SEER (seasonal energy efficiency ratio) ratings and installation is uncomplicated, usually completed in a single day.

A ductless mini split is not maintenance-intensive but should receive regular user upkeep and a yearly maintenance check-up by an HVAC professional. Here are a few things you can do yourself:

  • Inspect the air filters incorporated in the indoor air handler monthly. During cooling season, monthly cleaning according to manufacturer’s instructions is a good idea.
  • The IAQ (indoor air quality) filter usually has its own maintenance cleaning schedule expressed in hours of use. Check the owner’s manual for proper cleaning interval. Many units have indicator lights to remind you to clean the IAQ filter.
  • Inspect the indoor coil for dirt accumulation. In most applications, coil cleaning can be performed as part of a regularly scheduled annual maintenance procedure by your HVAC contractor, who’s equipped with the cleaning solutions and tools to do the job.
  • Shut the power off to the outdoor condenser/compressor unit. Remove the top of the unit and inspect the condenser coil. Remove debris such as leaves or grass clippings. Also cut back any vegetation that may be encroaching on the unit and blocking airflow. Replace the top and restore power to the unit.
  • Inspect the refrigerant fittings and conduit for signs of refrigerant leaks, usually indicated by oily spots. Contact your HVAC contractor if you spot any.
