Mini Split Freezing Up or When the Appliance Overcools the Air
Behind the mini split freezing up problem, when we mean that to the air conditioning system provides excessively low temperatures, several reasons may be at play. Let's break through each of them. We discussed thermostats in the previous article, but let's recall: a thermostat is that indoor part of the mini-split system that hangs on the wall. It consists of a sensor that measures the temperature of the room. When this temperature reaches the value you set up, the sensor triggers a switch that closes off the operation of a mini-split system. When the temperature changes, the temperature sensor activates the switch again, and the equipment resumes operation. In this case, if you set the thermostat to an overly low temperature, the mini-split will keep freezing the room beyond this set point. The same applies to the controller, which is the remote control. The solution here is straightforward: adjust the system to a higher temperature using the remote control. Usually, the temperature is displayed on the indoor unit's display, i.e., the thermostat.
The capacity of a mini-split system is the first factor considered when selecting HVAC equipment. If your climatic appliance is excessively freezing the room, the explanation may be quite simple: the equipment was chosen for a larger space. In that case, the mini-split will rapidly and intensely cool the air, almost freezing it. Is it possible to solve the issue without purchasing another mini-split system? It's possible. Try setting a higher temperature and reducing the equipment's intensity manually by adjusting the power and fan speed using the controller. If the problem persists, reach out to our service team. Our specialists will provide guidance on possible solutions.
Possible reasons for the problem of mini split freezing up include improper or insufficient system maintenance, leading to clogged filters or heat exchangers. Additionally, other system issues like sensor malfunctions, etc., can be why the mini-split freezing the room. Let's make it clear upfront that in such cases, we do not recommend attempting to resolve the issue on your own. Anything related to diagnosis and potential disassembly of the appliance is best left to professionals. Give us a call, and we can handle it all!
