Zone Air Mini Splits

DIY Mini Split Installation, At a Glance

This infographic summarizes the DIY mini split install path Zone Air customers follow with a pre-charged system. A typical first-time install runs 4–6 hours and saves $1,500–$3,500 compared with hiring a contractor. The biggest time savings come from skipping the deep vacuum step — pre-charged line sets ship with refrigerant already inside, so you only need to torque the flares, secure the conduit, and energize the unit.

Tools required: 4mm hex driver, adjustable wrench, level, drill with 3" hole saw, refrigeration torque wrench (1/4" and 3/8"), and a multimeter. Materials: outdoor pad or wall bracket, 14/4 disconnect whip with breaker, line set cover, and condensate drain.
