There is no 'assurance' that an RV AC unit won't freeze. Freeze up can happen to any RV Air Conditioner if the situation is right. High heat and high humidity will make it more prevalent. There are a few things you can do to help prevent it:
- Keep the intake filters CLEAN.
- High Heat and High humidity means the fan should be on HIGH.
- Set the thermostat to a moderate setting - not as cold as you can get it.
- Ventilate when you cook or shower by opening a roof vent. If humidity is built up in the trailer, it will wind up in the AC unit, and it can condense and freeze.
- Check the condenser every season. Look for debris or damage. If the fins are bent, use a radiator comb to straighten them back out.
- If the fan squeals or makes an uneven sound, it may need replacing. Bad fans can also (sometimes) cause a freeze up.
If it freezes up, turn the fan on high but AC off. Give it some time and the ice will melt - hopefully, before you do.
