This lack of airflow is most commonly caused by a buildup of dirt between the fins of the coil. Regardless of the reason, the ice will form because without adequate air flow the condenser coils will get too cold. These coils are typically kept just above freezing by the constant flow of air across them.

Can a heat pump freeze up in heat mode?
If there is not enough refrigerant in your system, it can't absorb as much heat. As a result, the coil may freeze if the outside temperature drops below 32 degrees Fahrenheit. Furthermore, as your heat pump naturally ices up in cold temperatures, there may not be adequate refrigerant to defrost the heat pump.
What temperature should I keep my mini split at?
A winter temperature of 68°F, and lower while you're away, is ideal for most homes. For summer, that number rises to 78°F when you're at home. The idea is to set the temperature as high as is comfortable in the summer and as low as is comfortable in the winter.
How often should a mini-split go into defrost mode?
approximately every 40 minutes.

Do mini splits go into defrost mode?
Most ductless mini-splits are equipped with a defrost mode that is designed to prevent the buildup of ice. An internal thermostat monitors the outdoor coil's temperature and automatically kickstarts the defrost cycle when it gets too cold.
How do I keep my mini-split from freezing?
- Install the Outdoor Unit Under a Source of Coverage. During the winter, snowfall can accumulate on top of the mini-split's outdoor unit and prevent it from effectively drawing in air. ... - Elevate the Outdoor Unit. ... - Turn On the Mini-Split's Defrost Setting.
Can a mini-split freezing up in heat mode?
Most of the time, frost appearing on an outdoor heat pump cabinet is not an issue. In fact, the manufacturers expect it and build defrost controls into the system. Periodically, the heat pump will reverse the refrigerant flow to warm the coils and melt off the frost. But malfunctions can still occur.

Why does my heat pump keep freezing up?
Heat Pumps Often Ice Up During Cold Weather This happens when the pump generates heat, the refrigerant turns to gas and then condenses when it meets the outdoor coil. In winter temperatures, this condensation will freeze. That's why the pump also has a defrosting function.
Why is my condenser freezing up in heat mode?
Without sufficient airflow through the unit, moisture in the air can freeze on the evaporator or condenser coil. To prevent this, ensure good airflow by clearing away any leaves, debris or snow drifts that may be blocking the coils. If the coils are dirty, cleaning them may prevent freezing.

How do I keep my mini split from freezing?
- Install the Outdoor Unit Under a Source of Coverage. During the winter, snowfall can accumulate on top of the mini-split's outdoor unit and prevent it from effectively drawing in air. ... - Elevate the Outdoor Unit. ... - Turn On the Mini-Split's Defrost Setting.
Should you turn off mini split in winter?
Keeping Your Mini Split Working Through the Winter Temperature extremes inhibit a mini split system's ability to function effectively. Extremely high and low outdoor temperatures make it difficult for an air conditioner to eject or absorb heat, resulting in a decline in both performance and efficiency.
