Keeping That Ductless Mini Split Maintained Is Of Utmost Importance

Tuesday, July 09, 2013

You’ve installed a ductless mini split system in your home and now, during the height of the cooling months, it’s time to take full advantage of the cooling efficiency and home comfort it delivers. For maximum performance, follow these simple do-it-yourself tasks and schedule ductless mini-split maintenance with your Mitsubishi Electric Cooling & Heating contractor this season.

Easy DIY maintenance tips

Ductless mini splits are small air conditioners or heat pumps, all of which require similar care to ensure free airflow at the air handler(s) and outside cabinet for optimal cooling capacity. The outside compressor/condenser unit of a ductless mini split is compact by design and easy to overlook, especially if you’ve installed it in an inconspicuous area.

Make sure to check the outside unit on occasion to ensure that there are no obstructions to airflow. Check for leaves and debris that may be blocking airflow. Also, it’s easy for hedges, flowers or other landscaping to encroach upon the space around the unit, which should be kept clear by 4 or more feet in all directions.

Remove the air filter at each indoor air handler. Mitsubishi Electric ductless systems offer superior indoor air quality control, which require the occasional TLC like any other components. Clean the air filter, wipe the interior components and make sure the filter is completely dry before placing it back in the air handler.

Professional ductless mini-split maintenance

Ductless mini-split air conditioners and heat pumps require optimal refrigerant charge, clear drainage and good electrical contacts and function to deliver maximum efficiency and home comfort. Moreover, new features like inverter technology depend on optimal refrigerant charge for peak compressor performance to deliver superior dehumidification and comfort.

These are some of the primary checks and inspections of professional ductless mini-split maintenance:

  • Ensure optimal refrigerant charge for peak air conditioning and dehumidification capacity.
  • Run electrical diagnostics and check contacts.
  • Check compressor function.
  • Check airflow across the cooling coils.
  • Clear drainage of deposits and treat for algae and mold if needed.
