Single-zone vs. multi-zone mini-split — when does each make sense?

Single-zone for one room (sunroom, bonus room, garage office) — cheaper, simpler install. Multi-zone for whole-home retrofit without ductwork — one outdoor unit feeds 2–5 indoor heads. Multi-zone runs ~$3,000–$5,000 per added zone; at 4+ heads, compare against a ducted mini-split system.

How long can the refrigerant line set run from outdoor to indoor head?

Typical residential mini-splits handle 50 ft horizontal + 30 ft vertical without performance loss. Beyond that the installer must add refrigerant per manufacturer spec and ensure proper oil return — skipping this is a common cause of premature compressor failure.

What does HVAC service typically run in Tempe, AZ?

Mini-split typically runs $2,250–$5,850, and mini-split multi-zone runs $8,100–$17,950 in Tempe, Arizona. See the HVAC pricing table on this page for the full per-service breakdown.
