Proper installation planning is crucial for AC performance and longevity. A poorly planned installation can result in inefficient cooling, higher energy bills, and premature equipment failure.
Choosing the Right Location
Indoor Unit Placement
- Height: 7-8 feet from floor for optimal air circulation
- Distance from ceiling: Minimum 6 inches for airflow
- Away from heat sources: Not near TVs, computers, or direct sunlight
- Accessible for maintenance: Space for filter cleaning and servicing
Outdoor Unit Placement
- Ventilation: Minimum 2 feet clearance on all sides
- Away from bedrooms: Compressor noise can disturb sleep
- Shade preferred: Direct sun reduces efficiency
- Level surface: Prevents vibration and drainage issues
Electrical Requirements
- Dedicated circuit: AC should have its own breaker
- Proper wire gauge: Based on unit amperage
- Voltage matching: 220V for most split units
- Grounding: Essential for safety
Refrigerant Piping
Pipe length affects efficiency and cost:
- Short runs (under 15m): Minimal efficiency loss
- Long runs (over 25m): May need additional refrigerant
- Elevation changes: Each meter of height adds resistance
Hidden Installation Costs
- Wall drilling and patching
- Electrical work if circuit doesn't exist
- Platform or bracket for outdoor unit
- Drain pipe extension
- Copper pipe cost for long runs
