Ductless Mini Split Operation in Colder Weather: Best Practices

If you have a ductless mini-split already or are considering one for your home, these tips can help you get more heat from it when the weather turns cold. Mini-splits are heat pumps, and while you’ll get all the heat you need from it most of the time, we do occasionally have bouts of excessively cold weather.Ductless Mini Split Operation in Colder Weather: Best Practices

  • Improve the insulation in the space the mini split conditions and seal any air leaks around the windows and the door frame. When you lower the heating load, the space will be much easier to keep warm.
  • Look for an HSPF (heating season performance factor) over the minimum, which stands at 7.7. Of course, a mini split with a SEER (seasonal energy efficiency ratio) rating over 13 will lower cooling costs, as well.
  • Tend to the outdoor condenser. It does snow in the Texas Panhandle from time to time, and when it does, remove the snow that collects around and on top of the mini split. To be on the safe side, you can also build a temporary or permanent cover to stop snow from falling on the top of the condenser, making sure it sits far enough above the mini split so air circulates freely from the top of the condenser.
