28,000 BTU/2.33 TON V/O 22 seer

A 28 k BTU (≈2.3-ton) mini-split is best suited for large open areas of ~1,350–1,600 ft² with average insulation. It’s also common in 3-zone systems (e.g., 9k+12k+12k). Use a Manual J load calculation—and factor in diversity (typically 80–85%) when sizing multi-zone systems—to avoid oversizing, which can reduce efficiency and dehumidification.

Yes—many 28k BTU condensers support 3 indoor units (e.g., 9k+12k+12k). Modern inverter compressors manage each zone’s demand dynamically. To ensure efficiency, total indoor capacity should align with a diversity factor of ~0.8–0.9.

A 28 k BTU outdoor mini-split typically runs on 208–230 V with ~23 A minimum circuit ampacity and requires a 25–30 A breaker and #10 AWG copper wire. Install a dedicated two-pole breaker plus a code-required disconnect near the unit.

Mount the outdoor condenser level on a sturdy bracket or concrete pad, clear of debris, and anchored for wind stability. Refrigerant line sets must be carefully routed—avoid kinks, protect with insulation and weatherproofing, and size heads based on line-set length.
