FAQs

This unit uses R454B refrigerant. This unit comes pre-charged with R454B refrigerant for up to 24.5 feet of lineset. If your installation does not exceed this length, no additional refrigerant is needed.

Yes, for multi-zone units, you can go back to the product options to select different lineset lengths for each indoor unit.Please note, if the extended lineset is longer than 25 feet, additional refrigerant will be required. Make sure to consult a professional HVAC technician for proper installation.

In auto mode, the unit automatically switches between cooling and heating to maintain the set temperature. You can adjust the target temperature manually—typically between 60°F and 86°F —depending on your comfort.

The mini split condenser and lines are not pre-vacuumed. You will need to vacuum the system during installation to remove air and moisture before releasing the refrigerant—this is essential for proper operation and longevity. You can use our Rental Kit Service, which includes all the necessary tools for vacuuming and installing your mini split.
