How You Can Prepare Your Ductless Air Conditioner for Winter
Mitsubishi ductless air conditioning systems (also called ductless mini-splits) are incredibly efficient as they can be used for both heating and cooling purposes. This makes for cost effective operation as they can work as air conditioners and heaters based on the season. A ductless AC can be converted to ductless heating with the simple touch of a button on the thermostat.
So how can you prep your ductless mini-split system for winter?
Clear outside units
The external portion of your ductless system can become clogged with dust, dirt and other forms of debris over the summer months. To ensure optimum efficiency, clear away any surrounding weeds, leaves and other debris and remove any blockages that reduce efficiency. Ensure that your interior cooling coil and condenser coil (outside) are cleaned and in top working condition. You can use a garden hose to spray and clean the unit. Annual maintenance is suggested by the ductless AC manufacturer’s, including Mitsubishi.
Clean the air filter
Most ductless systems require you to clean the filter at least every three months. If you don't clean the filter and allow dust and dirt to build up, the result will be reduced efficiency, decreased air flow, an increase in your energy bills, and a reduction in the quality of air within the conditioned space.
Call a technician
Ductless heat pumps may struggle during the winter if they are not properly maintained. You should ideally schedule your yearly system checkup before the onset of winter so an HVAC professional can ensure that your ductless mini-split is functioning optimally. If you schedule a maintenance check during a busy season, the cost will be greater than it would be during the off season.
Position the indoor unit properly
Ductless air conditioning systems indoor sections should be kept away from any furniture that gathers a lot of dust. Whenever possible, ask the installer to place the unit on an exterior wall, centered and positioned for the best air distribution. Proper placement of the indoor unit is critical to ensuring the heated and cooled air is efficiently circulated throughout the space
