How Much Does Air Conditioner Installation Cost?

In short, air conditioner installation costs between $1,795 and $25,000 in Australia, with most Queensland homeowners spending around $2,500 for a quality split system installation. However, the final price depends on system type, property size, and installation complexity.

Let’s break down the most important factors now. 

Split system air conditioner installation cost

Split system air conditioners represent Queensland’s most popular choice, ranging from $1,795-$4,815 for supply and installation. Entry-level 2.5kW systems start around $1,795, while premium 7-9kW units reach $4,815.

Standard 3.5kW units suitable for medium rooms cost $2,200-$2,750, while larger 7.2kW systems for open-plan areas cost $3,300-$4,200 across Brisbane, Gold Coast, and regional Queensland.

Installation timeline expectations

Standard split system installations require 4-8 hours for completion, while complex installations involving electrical upgrades or challenging access may extend to full-day projects. 

Multi-split systems connecting several indoor units to one outdoor unit typically require 1-2 days for proper installation and commissioning.

Reverse cycle air conditioner installation cost

Reverse cycle air conditioners provide year-round climate control across Queensland. These units cost 10-15% more than cooling-only systems but efficiently handle both humidity cooling and winter heating.

Quality reverse cycle split systems range from $2,100-$5,200 installed, however, energy-efficient inverter models cost more upfront but deliver significant electricity savings.

Commercial vs residential considerations

Queensland businesses require robust climate solutions that maintain consistent temperatures across larger spaces. Our commercial solutions address these unique requirements with specialised equipment and installation techniques designed for commercial environments.

Commercial installations often involve multiple indoor units, complex electrical configurations, and compliance with building regulations. Ducted commercial systems range from $14,000-$25,000 installed, while multiple split systems may cost $8,000-$25,000 depending on coverage requirements. 

Note: Packaged systems for large buildings are often over and above these amounts, given the complexity of their installation & access.

Let’s explore the factors that typically increase installation complexity and costs by 30-50% compared to residential projects next.

Installation complexity factors

Your property’s specific characteristics can significantly impact installation pricing. 

Wall materials, electrical supply location, and unit positioning affect labour requirements, while brick veneer homes typically require additional drilling time. Homes with concrete or steel framing may need specialised equipment to ensure a successful installation.

Distance between indoor and outdoor units also influences costs. 

Standard installations accommodate up to 5 metres of refrigerant piping, but longer runs require additional materials and labour.

What affects your installation investment

Several variables determine your air conditioning installation investment:

• System capacity: Larger units require more materials and labour 
• Electrical work: Dedicated circuits or switchboard upgrades add $300-$1,200  
• Additional cost: Permits, ductwork modifications, existing system removal
• Installation complexity: Wall materials, positioning, and accessibility affect labour

Professional contractors will provide transparent estimates covering all costs upfront.

Knowing your costs upfront helps

A recent client of ours from Gympie discovered her 1980s brick home required a new 20-amp circuit for her 7.2kW reverse cycle system. We explained this electrical upgrade would add $650 to her $3,200 installation quote. By understanding these additional costs upfront, she could budget appropriately and avoid installation day surprises that often catch homeowners unprepared.

Smart ways to reduce installation costs

Reduce your air conditioning installation spend with these tips:

• Seasonal timing: Schedule during April-August for 10-15% discounts 
• Multiple quotes: Compare estimates for competitive pricing 
• Property preparation: Clear pathways to save labour time 
• Correct sizing: Avoid oversized systems that cost more without added benefit

Getting quotes from multiple contractors will reveal price variations and help identify the best value for you.

System efficiency considerations

Higher efficiency systems cost more initially but deliver substantial savings. A 5-star energy-rated unit costs $300-$500 more than 3-star models but saves $150-$250 annually on electricity bills.

Tip: Clean your air conditioner regularly to maintain peak performance, extend your equipment life and warranty coverage.
