- Tubing cutter and bender
- Torque wrench set
- Multimeter
- Leak detector
- Level
- Power drill with bits
Step-by-Step Installation
- Site Selection: Choose appropriate locations for indoor and outdoor units considering airflow, drainage, and service access requirements.
- Mounting Preparation: Install mounting brackets for indoor unit and prepare concrete pad for outdoor unit ensuring level surface.
- Refrigerant Line Installation: Run copper refrigerant lines between indoor and outdoor units, ensuring proper insulation on suction line.
- Electrical Connections: Connect power supply wiring according to local electrical codes and manufacturer specifications.
- Drain Line Installation: Install condensate drain line with proper slope and trap to ensure proper drainage.
- Vacuum and Charge: Evacuate system to 500 microns minimum, then charge with specified refrigerant type and quantity.
- System Startup: Power up system, check all operations, verify proper airflow and temperature differentials.
- Final Testing: Perform complete system test including cooling/heating modes, thermostat calibration, and safety controls.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit not cooling/heating | Power loss, thermostat issue, refrigerant leak | Check circuit breaker, verify thermostat settings, check refrigerant charge |
| Poor cooling performance | Dirty filters, low refrigerant, restricted airflow | Clean/replace filters, check refrigerant charge, clear obstructions |
| Unit cycles on/off frequently | Dirty coils, oversized unit, thermostat location | Clean coils, verify proper sizing, relocate thermostat if needed |
| Water leakage from indoor unit | Clogged drain line, improper slope, frozen coil | Clear drain line, ensure proper slope, check for ice formation |
| Unusual noises | Loose parts, debris in fan, compressor issues | Tighten all fasteners, clear debris, check compressor mounting |
| High energy consumption | Dirty filters, refrigerant issues, duct leaks | Maintain clean filters, verify charge, seal ductwork |
| Frozen evaporator coil | Low airflow, low refrigerant, dirty filter | Check fan operation, verify charge, replace filter |
Error Codes
