To solve and prevent the problem of freezing mini-split heat pumps, the following measures are recommended:
Clean and replace the air filter regularly to ensure good air circulation.
Regularly check and maintain the refrigeration system to ensure that the refrigerant is sufficient and there are no leaks.
Set the indoor temperature reasonably, and avoid setting it too low when the outside temperature is very low.
Regularly check the drainage system to ensure that water can be drained out smoothly.
