FAQ's
What kind of refrigerant does this unit use?
This system uses R-410A refrigerant and comes pre-charged for 25 feet of line set. If your installation exceeds this length, additional refrigerant will be required. Please consult a licensed HVAC technician to properly add refrigerant during installation.
Can I get longer extensions for this installation kit?
Yes, you can purchase additional line sets in our store.
When the unit is in auto mode, what will the room's temperature be maintained at?
