Florida is not exactly a frigid hellscape during the winter. That doesn’t mean that it’s a good thing to have your ductless system blowing cold air during the coldest months of the year, however. If your ductless system is blowing cool air for some reason, it’s very likely a problem with the reversing valve. While you’re waiting for a technician to arrive and fix it for you, read on to find out why it happens in the first place.
The Reversing Valve
The reason that ductless mini splits, along with all other heat pumps, are able to switch back and forth between heating and cooling modes is that they can change the direction their refrigerant flows. They are able to do this using a part called the reversing valve, which sits in the refrigerant line. The reversing valve contains a slide that moves back and forth between the two positions. The slide is controlled by an electromagnet called the solenoid. The system’s ability to switch modes depends entirely on this valve.
There are two ways in which the valve can develop problems. The first way is that the slide becomes stuck in the valve. A professional will need to open the valve and free the slide in order to restore proper function. The second way the valve could break is that the solenoid could lose its charge. If this happens, the only thing to be done is to replace the solenoid. Obviously, you should rely on a professional to do that for you. Once the reversing valve is restored to proper function, it should solve the problem.
