Why Maintenance for Ductless Mini Splits Should Be a Regular Affair

Posted by Paul Wadsworth on Wed, Apr 03, 2013 @ 02:07 PM

Maintenance for ductless mini splits should include periodic do-it-yourself care and scheduled professional maintenance to allow the unit to maintain optimal efficiency, performance and life expectancy.

ductless mini split maintenanceJust like a conventional air conditioner or heat pump, a ductless mini split depends on free airflow and optimal refrigerant charge to efficiently extract and release heat at the indoor and outdoor coils. This is the primary function of a ductless mini split, and it’s the process that affords these systems astounding performance and efficiency

Do-it-yourself care includes ensuring free airflow to and from the outdoor unit. Airflow blockages may stem from any number of obstacles, such as strewn debris, leaves, overgrown vegetation, garbage bins, ice accumulation from a leaky gutter, snow drift and more.

If you use your ductless mini split during the heating months, it’s imperative to prevent ice and snow accumulation, which can lead to the outdoor condenser coil freezing into a block of ice. Something as simple as a dirty air filter can compel ice buildup, too. If you utilize your ductless mini split regularly, check the filter on a monthly basis and no less than once every two months during seasons of use. Most of these units feature a cleanable filter that can be reinserted after it is cleaned.

Professional preventive maintenance

Ductless mini splits consistently deliver lasting and efficient performance with regular professional care. Ideally, you should include maintenance for ductless mini splits with regularly scheduled maintenance of your other home-comfort systems. Your HVAC professional performs the following tasks:

  • The outdoor and indoor coils are inspected for refrigerant leaks.
  • Refrigerant charge is checked.
  • If needed, the coils are deep-cleaned to ensure maximum heat exchange.
  • Electrical components are inspected for wear and function.
  • The filter(s) are removed, inspected and cleaned.
  • The blower assemblies for all indoor units are tested for proper balance and airflow.
  • Condensate drainage is inspected to ensure no blockages.
