2. System Components
2.1 GLZS4MA2410 Heat Pump (Condenser)
The outdoor unit, or condenser, is responsible for transferring heat between your home and the outside air. In cooling mode, it expels heat from indoors to the outside. In heating mode, it extracts heat from the outside air and transfers it indoors.

2.2 AWST24SU1308 Air Handler
The indoor unit, or air handler, circulates conditioned air throughout your home's ductwork. It houses the evaporator coil (for cooling) and the 8kW heat kit (for supplemental heating). This model supports both bottom and front return air configurations.

2.3 8kW Heat Kit
The factory-installed 8kW heat kit provides supplemental electric heating. This is particularly useful in colder climates or during periods of extremely low temperatures when the heat pump alone may not be sufficient to maintain the desired indoor temperature.

4. Installation
Installation of this Goodman Heat Pump System must be performed by a qualified HVAC technician. Improper installation can lead to reduced efficiency, system damage, and void the warranty. Refer to the detailed installation instructions provided with the physical product for specific wiring diagrams, refrigerant line sizing, and ductwork connections.
Key Installation Considerations:
- Unit Placement: Ensure proper clearance around the outdoor condenser for adequate airflow. The air handler should be installed in a suitable indoor location (e.g., utility closet, attic, basement) with access to return and supply ductwork.
- Refrigerant Lines: Correct sizing and proper evacuation of refrigerant lines are critical for system performance.
- Electrical Connections: All electrical wiring must comply with local and national electrical codes.
- Ductwork: Ensure ductwork is properly sized, sealed, and insulated for optimal air distribution and efficiency.
- Condensate Drainage: Proper drainage for the air handler's condensate pan is essential to prevent water damage and mold growth.
5. Operating Instructions
Your Goodman Heat Pump System is controlled via a compatible thermostat. Familiarize yourself with your thermostat's specific operating instructions.
Basic Operation:
- Power On/Off: Use the system switch on your thermostat to turn the unit on or off.
- Mode Selection: Select 'Heat' for heating, 'Cool' for cooling, or 'Auto' for automatic switching between modes based on your set temperature.
- Temperature Setting: Adjust the desired temperature using the up/down arrows on your thermostat.
- Fan Settings: Choose 'Auto' for the fan to run only when heating or cooling, or 'On' for continuous fan operation.
6. Maintenance
Regular maintenance is crucial for the efficient and long-lasting operation of your heat pump system. Always turn off the power to the unit before performing any maintenance.
6.1 Air Filter Replacement
The air filter in your air handler should be checked monthly and replaced or cleaned as needed, typically every 1-3 months depending on usage and household conditions. A dirty filter restricts airflow, reduces efficiency, and can damage the system.
6.2 Coil Cleaning
The outdoor condenser coil and indoor evaporator coil should be kept clean. Dirt and debris on the coils can hinder heat transfer and reduce efficiency. This task is best performed by a qualified technician during an annual service check.
6.3 Annual Professional Inspection
Schedule an annual inspection and tune-up with a qualified HVAC technician. This ensures your system operates at peak efficiency, identifies potential issues early, and helps extend the lifespan of your equipment.
7. Troubleshooting
Before calling for service, check the following common issues:
- No Power: Check the circuit breaker for the indoor and outdoor units. Ensure the thermostat is set to the correct mode and temperature.
- No Cooling/Heating: Verify thermostat settings. Check if the air filter is clean. Ensure outdoor unit is not blocked by debris.
- Unusual Noises: Minor noises are normal, but loud or persistent sounds may indicate an issue. Turn off the unit and contact a technician.
- Poor Airflow: Check for dirty air filter or blocked return/supply vents.
For any issues beyond basic troubleshooting, contact a qualified HVAC technician. Do not attempt complex repairs yourself.
