FAQ

Do I need to hire an electrician?
While the refrigerant lines are DIY, you will need a dedicated 230V circuit installed by a qualified electrician to power the outdoor condenser.

Can I mix and match indoor unit sizes?
Yes, these systems support mixed BTU combinations (e.g., 9K + 12K + 18K) as long as they fall within the condenser's total capacity limit.
