What changes your AC installation quote?
The same unit can quote differently depending on access, electrical work, pipe runs and how carefully the system is sized.
High impact
System capacity
A 2.5kW bedroom unit is a very different job to a 16kW ducted system with zones.
$300-$1,500
Electrical work
Dedicated circuits, isolators and switchboard upgrades can change the final quote.
$80-$150/m
Access and pipe run
Two-storey homes, long pipe runs, wall brackets, roof access and drainage runs add labour.
10-30%
Brand and controls
Premium brands, WiFi controls, zoning, quiet models and high star ratings lift upfront cost.

Why use an ARCtick certified installer in Nightcliff?

Premium
Mitsubishi Electric
Durable, quiet systems with strong bedroom and living room split system options.

Nightcliff installer tip: installation quality matters more than brand
A budget brand installed perfectly will usually outperform a premium unit installed poorly. Compare installer experience, sizing process, warranty support and itemised scope.
Running costs
Reverse cycle AC is usually the cheapest electric heating option
Running costs depend on tariff, insulation, temperature settings and how often the system runs. Correct sizing and installation quality matter as much as the brand.
| Option | Hourly cost | Seasonal guide | Efficiency |
|---|---|---|---|
| Reverse cycle AC heating | $0.20-$0.40/hr | $300-$600 season guide | Best electric heating efficiency |
| Reverse cycle AC cooling | $0.25-$0.50/hr | $250-$500 season guide | Excellent with inverter systems |
| Gas ducted heating | $0.50-$1.00/hr | $750-$1,500 season guide | Good, but tariff dependent |
| Electric panel heater | $0.60-$1.20/hr | $900-$1,800 season guide | High running cost |
| Old non-inverter AC | $0.80-$1.50/hr | $800-$1,500 season guide | Often expensive to run |
