Step-by-Step Installation Guide
Step 1: Preparing the Installation Site
- Place the condenser on a concrete pad or a pre-installed mounting bracket.
- Use a level to ensure the unit is properly aligned.
- Secure the unit to prevent vibration and movement.
Step 2: Connecting the Refrigerant Lines
- Ensure the refrigerant lines are properly sized and free from damage.
- Cut and connect the liquid and suction lines using a pipe cutter and torque wrench.
- Braze the connections using nitrogen to prevent oxidation inside the tubing.
- Check for leaks using a refrigerant leak detector.
For best practices on brazing, refer to this HVAC brazing guide.
Step 3: Wiring the Electrical Components
- Shut off the power at the main circuit breaker before starting.
- Connect the high-voltage power supply to the unit following the Goodman wiring diagram.
- Attach the low-voltage control wiring from the thermostat.
- Use a multimeter to check for proper voltage before turning on the power.
More details on HVAC electrical wiring can be found at Electrical Basics for HVAC.
Step 4: Vacuuming and Charging the System
- Attach a vacuum pump to the service valves and pull a deep vacuum of at least 500 microns.
- Verify that there are no leaks before charging the system with R-410A refrigerant.
- Charge the system according to the manufacturer’s specifications.

Step 5: Testing and Final Checks
- Turn on the power and thermostat.
- Observe the unit’s operation to ensure it’s cooling efficiently.
- Listen for unusual noises that might indicate loose parts or incorrect installation.
- Measure airflow and refrigerant pressure to confirm performance.
Common Installation Mistakes and How to Avoid Them
1. Skipping Vacuuming Process
Failing to remove air and moisture from the system can cause efficiency loss and damage to internal components. Always perform a vacuum before charging the refrigerant.
2. Incorrect Electrical Wiring
Improperly connected wires can result in electrical hazards and system failure. Always follow the Goodman wiring diagram and local electrical codes.
3. Poor Location Selection
Installing the unit in a poorly ventilated or cluttered area reduces airflow and efficiency. Ensure adequate spacing and ventilation for optimal performance.
4. Overcharging or Undercharging Refrigerant
Incorrect refrigerant levels affect cooling performance and energy efficiency. Use manufacturer guidelines and a refrigerant gauge to ensure proper charging.
