GE 18,000 BTU Inverter Airco 220v 21 Seer

An 18,000 BTU 208–230V GE Inverter Ductless Mini-Split (typically in GE's Altitude or Endure series) rated around 21 SEER/SEER2 delivers high-efficiency cooling and heating for spaces between 750 and 1,000 sq ft.

Key System Performance Specifications

Core Performance Features

• A-PAM DC Inverter Rotary Compressor: Continuously ramps compressor speed up or down to maintain exact room temperatures without power-spiking cycling.

• Hydrophilic Blue Fin Coils: Pre-coated outdoor and indoor aluminum coil fins maximize water runoff and resist environmental corrosion.

• Built-In Wi-Fi (SmartHQ App): Allows temperature modification, fan control, and scheduling directly from a mobile device.

• Quiet Indoor Operation: Multi-speed fan curves produce indoor sound levels as low as 29 to 35 dBA during low-stage cooling.

Electrical & Field Installation Notes

1. Dedicated Breaker Circuit: Requires a 220V dedicated line from the main service panel to an outdoor local disconnect switch using 12/2 or 10/2 NMB wire.

2. Interconnect Harness: Requires a 14/4 AWG stranded/shielded 4-conductor control cable run between the condenser and the indoor wall handler for power and data.

3. Flared Lineset Procedure: Connections are flared; installers must pull a deep vacuum to under 500 microns before cracking open the factory R410A/R454B refrigerant valves.
