Goodman markets the GSX13 air conditioner as an efficient and
reliable product. This three-phase 13 SEER split-system series has
models ranging in capacity from 1.5 to 5 tons and producing anywhere
from 18,000 to 60,000 BTU/H.
The Smartcoil technology used to enhance the GSX13’s heat
transfer capability incorporates refrigeration grade, rifled, 5 mm
copper tubing and aluminum fins that reportedly provides a
larger-than-average surface area. The coil is protected by a steel
louvered guard. The GSX13 also is designed with features meant to
soften the operational sound. For example, it has a three-bladed
condenser fan covered by a louvered sound-control top.
Goodman produces the GSX13 with a louvered cabinet made
with heavy-gauge galvanized steel. The cabinet has a side panel that
allows access to the controls and provides enough space for accessories.
The liquid and suction line service valves are made of brass.
