What our customers say

Factors that influence your installation cost

Your property’s specific characteristics can significantly impact installation pricing. Here’s what affects costs depending on your region:

System capacity

Larger units require more materials and labour. Homes in Hervey Bay’s coastal areas or Gympie’s inland suburbs often need appropriately sized systems to handle Queensland’s humidity and heat effectively.

Electrical work 

Dedicated circuits or switchboard upgrades add $300-$1,200 to your installation. This is particularly common in older homes throughout the Fraser Coast and Gympie regions.

Installation complexity

• Wall materials and property accessibility affect labour requirements
• Standard installations include up to 5 metres of piping; longer runs cost more
• High-set homes require more labour than single-storey installations

Factors like permits, ductwork modifications, and existing system removal can also affect your final investment.

The installation process: What to expect

The timeline: Standard split system installations require 4-8 hours for completion. Complex installations involving electrical upgrades or challenging access may extend to full-day projects. Multi-split systems connecting several indoor units typically require 1-2 days for proper installation and commissioning.

What’s included: Professional contractors provide transparent estimates covering all costs upfront, including mounting, electrical connection, piping, drainage, testing, and system walkthrough.

When to replace vs repair your air conditioner

Not sure whether to repair your existing system or invest in a new installation? Here’s how to decide:

Consider replacement when:

• Your system is 10+ years old
• Repair costs exceed 50% of a new system’s price
• You’re experiencing frequent breakdowns or weak airflow
• Your electricity bills keep rising despite regular use
• The system struggles to maintain consistent temperatures

Why new systems are worth it: 

Modern air conditioners offer 30-40% better energy efficiency (potentially saving you $150-$250 annually), quieter operation, improved air quality, smart home compatibility, and better humidity control for Queensland’s climate. A 5-star energy-rated unit costs $300-$500 more initially but pays for itself within 2-3 years through electricity savings.

However, repairs may be a better option if your system is less than 7 years old, the repair cost is minor (under $500), and the system has been well-maintained

Smart ways to reduce installation costs

• Seasonal timing: Schedule during April-August for potential 10-15% discounts
• Multiple quotes: Compare estimates from local contractors for competitive pricing
• Property preparation: Clear pathways and installation areas to reduce labour time
• Correct sizing: Our technicians help you avoid oversized systems that waste money
• System efficiency: Higher-efficiency systems cost more initially but deliver long-term savings
