How to Optimize Your Ductless Mini Split When Cooler Temps Hit the Southeast

Published on: September 16, 2013

A ductless mini split is one of the most energy efficient and cost efficient ways to keep your home warm during the cooler months, since without ductwork, these systems don’t see the energy and air loss that forced-air systems experience. If you have a ductless mini split installed in your home and are looking for additional ways to optimize it for the colder weather, consider following these helpful tips.

Use Proper Mounting

Different models have different recommendations for how and where to install the air handlers in rooms. Follow those recommendations carefully, since the manufacturer will know the best practice. For example, some mini split air handlers should be installed near the ceiling, while some other models recommend much lower installation.

Avoid the Snow

Try to keep the outdoor condensing unit at least two feet above ground level to keep air flowing. While heavy snow is not common in the Southeast U.S., some of the northern parts of the region can get a good snowfall occasionally. To protect your ductless mini split outside unit from the elements, consider placing it under a roof extension or overhang, or on an open porch. If snow builds on top of the outside unit, the evaporator will be forced to work overtime in order to melt the snow. Because of this, your house won’t heat quickly enough. For optimal performance, try your best to keep all snow away from the outdoor unit, even if you see snow only a few times a year.

Prevent Cold Spots

Because a ductless heating unit must work harder to keep your home warm during the winter months, it’s crucial to understand how to set the temperature when your house is unoccupied. As a general rule, it’s recommended that you keep your unit around 50 degrees and the air circulating throughout your home, to prevent cold spots from forming.
