MULTI – HEAD AIR CONDITIONERS SUCK BALLS
Thinking of going multi-head? Before you lock it in, take a look behind the glossy brochures. You may be paying more — for less.
The Manufacturing Economics
Multi-head systems are niche, meaning they’re not produced at scale. That makes them expensive — not because they’re better, but because they’re rarer.
Key Takeaway: You’re paying for rarity, not performance.
The “30/30” Cost Trap
1. Purchase Cost
A multi-head system can cost about 30% more than buying three separate units.
2. Installation
Longer copper runs, more labour hours. Multi-head installs are harder, not easier.
Efficiency & Long-Term Running Costs
A single 9kW compressor running one bedroom? That’s inefficient by design.
Multi-heads must push refrigerant further. Longer pipe runs = more energy use = higher bills.
Redundancy: Single Point of Failure
One system goes down, the whole house gets hot. With individual splits, you still have backups.
Individual Splits
If one fails, the others keep running.
Multi Head
If the main unit fails, you’re out of luck.
The Verdict
If you’re not restricted by space, you’re better off with standard split systems. Lower cost, more efficiency, and no single failure point.
