Ductless mini splits have a full list of advantages, from their efficiency to simplistic installation, which is why so many homeowners opt for this system as their primary heating and cooling system. While ductless mini splits have so many benefits, these systems are occasionally going to have problems, especially during the heating season. Problems in the winter are most often relative to a lack of thermal energy to create enough heat, which is a problem also called a thermal dearth. Here is a look at some of the more common woes you can run into with your ductless mini split system in the winter and why a thermal dearth could be to blame.
Problem: The system is not producing enough heat.
This is common with ductless mini split systems because these systems work much like a heat pump; they harvest thermal energy and use that to heat your home. If you have an excessively long period of cold temperatures, your mini split may not have enough thermal energy to pull to provide heat. In some cases, there will be nothing you can do about this problem, but it is always worth having a professional take a look to ensure there is not a bigger problem going on.
Problem: The system is kicking off even though your home is not the desired temperature.
Once again, the lack of thermal energy can be your culprit with this kind of problem. Some systems are actually designed to kick off if there is not enough energy to produce heat in the environment. This occurs to prevent the system from pushing cooler air into your home and actually cooling it instead of warming it. Most modern systems do shut down in a thermal dearth situation, but not all of them. And if you have an older system, it will probably continue to blow whatever air it is able to produce into your home, even if it is not the proper temperature.
Problem: The system is accumulating ice buildup on the exterior vent system.
In many situations, this can be a reaction caused by the release of condensation during the heat exchange process, because the environment is cold enough to cause freezing. For the most part, this will not happen if enough thermal energy is being harvested to prevent freezing, so once again, a thermal dearth could be to blame. If you are having issues with heat production and you have ice accumulation on the exterior system, it is the most likely problem.
