Ductless mini split outdoor units are much smaller than the conventional air conditioner units we are accustomed to seeing. They are shaped like a suitcase and take up less space then a conventional unit.

Sound Levels

The decibel ratings on a Fujitsu ductless mini split are about 50% less than a conventional outdoor unit. The low sound levels make it possible to install the outdoor unit in locations that you would never install a conventional outdoor unit.

Mounting Stands

We often get asked why we mount the outdoor units off the ground. Many of the Fujitsu ductless mini splits we install are heat pumps. In the winter months the outdoor units have to defrost themselves. When a unit goes into a defrost cycle, the outdoor coil will warm up and defrost any moisture that has formed on the coil. If the unit is not up off the ground, a block of ice will start forming around the bottom of the unit. This ice block can stop the outdoor fan from running or damage the outdoor unit.

Types of Stands

The free-standing wire stand is attached to a plastic pad that is placed level on the ground. The Fujitsu ductless mini split is then bolted to the wire stand. These stands are unique to our area because they are made by a contractor in southern Minnesota that only sells them locally. Wall brackets are used when we cannot use a wire stand. The unit in this photo was mounted over a rubber flat roof, we would have voided the roof warranty by placing a piece of equipment on it.

Maintenance

The most important part of maintenance is keeping your outdoor unit coil clean. The condenser coil is what gets rid of all the heat that is removed from the home. Not cleaning your outdoor coil is like driving your car with the radiator covered in the summer. A well maintained outdoor unit will ensure a long life to your system. Clearing the snow off your outdoor unit will increase the capacity of your heat pump in the winter months.
