4. Setup and Installation
Installation of this central split unit heat pump system requires specialized knowledge and tools. It is mandatory that installation be performed by a certified HVAC professional to ensure safety, compliance with local codes, and proper system operation. Incorrect installation will void the warranty and can lead to serious hazards.
4.1 Key Installation Considerations:
- Site Selection: The outdoor condenser unit and indoor air handler must be placed in locations that allow for proper airflow, drainage, and accessibility for maintenance.
- Refrigerant Lines: The system uses R32 refrigerant. Proper sizing and connection of liquid and suction lines are critical. The condenser comes pre-charged with enough R32 to fill itself, a coil, and 15ft of line set.
- Electrical Connections: Ensure all electrical wiring complies with local and national electrical codes. The system requires 208/230 V, 1 Ph, 60 Hz power.
- Ductwork: Existing or new ductwork must be properly sealed and sized for efficient air distribution.
- Thermostat Wiring: Connect the thermostat according to the wiring diagram provided with the thermostat and air handler.
- Backup Heat Kit: The 5kW backup heat kit integrates with the air handler for supplemental heating.

5. Operating Instructions
Your system includes a 2 Heat / 1 Cool non-programmable thermostat. This thermostat provides basic control over your heating and cooling system.

5.1 Thermostat Functions:
- System Mode Switch: Selects operation mode:
- COOL: Activates the air conditioning function.
- OFF: Turns the system off.
- HEAT: Activates the heat pump or backup heat for heating.
- Fan Mode Switch: Controls the indoor fan operation:
- AUTO: Fan runs only when heating or cooling is active.
- ON: Fan runs continuously.
- Temperature Adjustment: Use the up/down buttons to set your desired temperature.
5.2 Heat Pump Operation:
Heat pumps efficiently transfer heat, providing both cooling in summer and heating in winter. In colder outdoor temperatures (typically below 32°F), the system may automatically engage the 5kW backup heat kit to supplement the heat pump and maintain desired indoor temperatures.

6. Maintenance
Regular maintenance is essential for the longevity, efficiency, and reliable operation of your Goodman HVAC system. Always ensure power is disconnected before performing any maintenance.
6.1 Air Filter Replacement:
- The air handler uses a filter size of 16" W x 20" L (406.4 x 508 mm).
- Check the air filter monthly and replace it every 1-3 months, or more frequently if you have pets or allergies. A dirty filter restricts airflow and reduces system efficiency.
6.2 Outdoor Unit Cleaning:
- Periodically clear away any debris (leaves, grass clippings, dirt) from around the outdoor condenser unit to ensure proper airflow.
- Gently rinse the outdoor coil with a garden hose to remove accumulated dirt. Avoid using high-pressure washers.
6.3 Professional Servicing:
- Schedule annual maintenance with a qualified HVAC technician. This includes checking refrigerant levels, electrical connections, coil cleanliness, and overall system performance.
7. Troubleshooting
Before contacting a service technician, review the following common issues and potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| System not turning on | No power, thermostat settings, tripped breaker | Check circuit breaker, ensure thermostat is set to HEAT/COOL, check thermostat batteries (if applicable). |
| No heating or cooling | Dirty air filter, blocked outdoor unit, low refrigerant, thermostat issue | Replace air filter, clear debris from outdoor unit. For refrigerant or thermostat issues, contact a technician. |
| Weak airflow | Dirty air filter, blocked vents, ductwork issues | Replace air filter, ensure all vents are open and unobstructed. Inspect ductwork for leaks or blockages. |
| Unusual noises | Loose parts, motor issues, refrigerant problems | Turn off the system immediately and contact a qualified technician for diagnosis and repair. |
If these steps do not resolve the issue, contact a qualified HVAC technician for further assistance.
