General Electric ns17h42sa4 Heat Pump 3.5 Ton 17 Seer

Product Description

The GENERAL ELECTRIC ns17h42sa4 is a 3.5-ton, 17 SEER single-stage heat pump outdoor unit built for residential split-system installations. The unit delivers both heating and cooling through a single-stage compressor, making it a straightforward replacement or new-install option for licensed HVAC contractors. Aluminum alloy tube and fin coils provide corrosion resistance and long service life. The cabinet is finished in gray and features a removable wire fan guard, giving technicians clear access to the coil and fan assembly during routine maintenance and service calls.

This unit is suited for residential applications where a 3.5-ton cooling and heating load has been calculated. The single-stage compressor operates at one capacity level, which keeps the control sequence simple and is compatible with standard single-stage thermostats and air handlers. Typical installations pair this condensing unit with a matched indoor coil and air handler or furnace. The aluminum alloy coil construction is particularly well-suited for humid or coastal environments where coil durability is a priority.
