General Electric ns17a42sa4 3.5 Ton 17 Seer Ac Unit

Product Description

The General Electric ns17a42sa4 is a single-stage residential air conditioner rated at 3.5 tons of cooling capacity and 17 SEER efficiency. Designed for split-system installations, this unit serves as the outdoor condensing section, rejecting heat from the refrigerant circuit to cool the conditioned space. At 17 SEER, it meets high-efficiency thresholds relevant to many regional energy codes. Licensed HVAC technicians handle installation and commissioning, including refrigerant line connection, electrical hookup, and system startup procedures.

This air conditioner is suited for residential and light commercial split-system applications where a 3.5-ton load calculation supports the equipment selection. Single-stage operation delivers consistent, full-capacity cooling output on each run cycle. It pairs with a compatible indoor air handler or coil and an appropriate line set to complete the refrigerant circuit. Proper system matching for SEER rating and refrigerant type is required to achieve rated efficiency.

Key Features

• 3.5-ton nominal cooling capacity for medium-to-large residential zones
