Goodman – 4.0 Ton Cooling – 48k BTU/Hr Heating – Heat Pump + Air Handler System – 15.2 SEER2 – 7.8 HSPF2 – R-32 (GLZS5BA4810 AMST48CU1300) – GLZS5BA4810 & AMST48CU1300

Internal Thermostatic Expansion Valve

• The AMST has a factory-installed internal thermostatic expansion valve. This streamlines installation and maintains ideal refrigerant flow for your system.

Efficient Circulation

• The direct-drive, multi-speed blower motor allows air volume variation for heating and cooling ensuring efficient circulation.

All-Aluminum Evaporator Coil

• Goodman’s evaporator coils use a reliable all-aluminum design featuring fins and grooved tubes. This design maximizes surface area and optimizes heat transfer for efficient comfort.

SmartFrame™

• This air handler features a rigid SmartFrame™ sub-structure for enhanced accessibility. It provides tool-less access to the filter rack and includes a coil mounting track that improves installation speed for all four compatible orientations.

Condensate Management

• The AMST includes a DecaBDE-free thermoplastic drain pan with secondary drain connections, these elements help prevent the formation of condensation and keep your system running smoothly.

Secure Cabinet

• This air handler features reduced noise levels, less than 2% air leakage, and enhanced durability due to its insulated, leather-grain embossed cabinet finish.

Energy-Efficient Compressor

• This unit utilizes an energy-efficient scroll compressor to provide refrigerant flow.

Smartshift™ Technology

• This unit features a time-delay defrost that enables a reliable, quiet, and smooth transition when the unit enters defrost mode.

Copper Tube/Enhanced Aluminum Fin Coil

• The condenser coil of this air conditioner is designed with aluminum fins and copper tubing to maximize efficiency. The fins serve to increase surface area, allowing the heat transfer capabilities of the materials to shine.

Factory-Installed Suction-Line Accumulator

• An accumulator prevents compressor damage from a sudden surge of liquid refrigerant and oil that could enter the compressor from the suction line.

Factory-installed compressor Crankcase Heater

• A crankcase heater is a supplemental electric resistance heater that prevents refrigerant migration by holding oil in the crankcase at a higher temperature than the coldest part on the system.

Factory-Installed High-Capacity Muffler

• A muffler reduces noise and high-frequency vibrations that can easily be transmitted through the tubing and into the house.

High And Low-Pressure Switches

• A pressure switch will suspend heat pump operations if it detects an unsafe pressure level.

Heavy-Gauge Galvanized-Steel Cabinet

• This cabinet is built to last. Galvanized steel construction, a durable and attractive architectural gray powder-paint finish with 500-hour salt spray approval, and a steel louver coil guard that protects your equipment from wear and tear.
