The GE 4-ton packaged heat pump rooftop unit (catalog 26B88, chassis QHA048S5DN1Y) provides reverse-cycle heating and DX cooling in a compact packaged curb unit. It suits electrification jobs where a compact heat pump RTU is specified.

Configured for 208/230V, 3-phase, and supports optional electric heat for backup/defrost and cold-climate design loads. Confirm electric heat kit sizing — heat pump capacity alone may not carry design winter conditions.

Review GE commercial literature for dimensions, refrigerant, and accessory compatibility. Do not assume Universal Fit curb or accessory kits apply to Compact RTU models without checking the specific model data.
