How Much Does HVAC Inspection Cost in Australia? [2025]

Regular HVAC (Heating, Ventilation and Air Conditioning) inspections are crucial for keeping your system running efficiently, preventing costly breakdowns, and ensuring optimal air quality.

Whether you’re a homeowner preparing for seasonal changes or a business owner maintaining commercial premises, an HVAC inspection helps you catch potential issues before they turn into expensive repairs. We already did the How Much Does HVAC Inspection Cost in Australia [2024]? But what about 2025?

In this comprehensive guide, we’ll break down average costs, what’s included in an inspection, the factors that affect pricing, and how to get the best value for your money.

What Is an HVAC Inspection?

An HVAC inspection is a professional evaluation of your heating and cooling system to ensure all components are functioning correctly. This includes checking:

• Air conditioners (split systems, ducted, or reverse cycle)
• Furnaces or heaters
• Ductwork and vents
• Thermostats and controls
• Air filters and coils
• Refrigerant levels
• Mechanical and electrical parts
• Safety mechanisms

A complete inspection helps identify worn-out parts, airflow issues, inefficiencies, or potential hazards like gas leaks or blocked filters.

How Much Does HVAC Inspection Cost in Australia in 2025?

The cost of HVAC inspection in Australia in 2025 typically ranges from AUD $150 to $450, depending on the type and size of the system, accessibility, and location.

Here’s a quick breakdown:

Type of HVAC Inspection	Estimated Cost (AUD)
Basic residential system check	$150 – $250
Full system diagnostic	$250 – $350
Commercial HVAC inspection	$300 – $450+
Ductwork inspection (optional)	$80 – $200
Add-on for air quality testing	$100 – $200

Factors That Affect HVAC Inspection Costs

Several variables influence how much you’ll pay for an HVAC inspection:

1. Type of Property

• Residential systems are generally cheaper to inspect than commercial ones due to their smaller scale.
• Commercial HVAC systems are more complex and require more time and specialised tools, raising the cost.

2. Size and Complexity of the System

• A small single-split system is faster to inspect than a large ducted reverse-cycle system with multiple zones.
• Systems with integrated air purifiers or smart thermostats may take longer to check.

3. Location

• Prices can vary between cities and rural areas. For example:
  • Sydney and Melbourne: slightly higher costs due to demand and labour rates.
  • Regional towns: fewer HVAC providers may lead to higher travel fees or limited availability.

4. Time of Year

• Booking during peak seasons (spring and autumn) when people prepare for hot or cold weather can be more expensive.
• Off-peak bookings (late summer or winter) may come with discounts or promotions.

5. Inclusions

• Some companies include duct cleaning, filter replacement, or minor repairs in their inspection package, while others charge separately.

What’s Included in a Standard HVAC Inspection?

A typical inspection includes the following checks and tests:

Visual Inspection

• Check for obvious damage, wear, leaks, and corrosion.
• Look for dust or debris buildup that may affect airflow.

Electrical System Testing

• Inspect wiring, terminals, relays, and capacitors.
• Ensure electrical connections are secure and safe.

Thermostat Calibration

• Test and adjust thermostat functionality.
• Confirm the system responds correctly to settings.

Refrigerant Check

• Measure refrigerant pressure and levels.
• Identify leaks or inefficiencies in the cooling cycle.

Airflow and Duct Check

• Test the airflow strength at vents.
• Inspect accessible ductwork for leaks, blockages, or insulation damage.

Safety Mechanism Review

• Test safety switches and shut-offs.
• Check carbon monoxide levels if gas heating is present.

System Efficiency Analysis

• Evaluate system performance.
• Recommend improvements to energy efficiency.

Some technicians also provide a detailed report with photos, test results, and maintenance suggestions.

How Often Should You Get Your HVAC System Inspected?

Experts recommend getting your HVAC system inspected at least once a year. However:

• Twice-yearly checks are ideal if you use both heating and cooling extensively.
• For commercial buildings, quarterly or bi-annual inspections may be needed to comply with building codes or warranties.

Regular inspections help catch minor issues early, which can save hundreds—or even thousands—of dollars in major repairs or emergency call-outs.

Is It Worth Paying for a More Detailed Inspection?

While a basic check might seem cost-effective, investing in a more comprehensive inspection is often worth it. Here’s why:

🔹 Preventative Maintenance Saves Money

Catching a loose wire, clogged drain, or dirty coil early can prevent a full system failure. Major HVAC repairs often cost $1,000–$3,000, so paying $250–$350 annually for an inspection is a smart investment.

🔹 Increased Energy Efficiency

A well-tuned HVAC system uses less power. You can reduce your energy bill by 10–30% simply by maintaining clean filters, coils, and ducts.

🔹 Prolonged Equipment Life

Routine inspections help extend the life of your system by keeping components in optimal condition. A good HVAC system should last 15–20 years, and regular maintenance plays a key role in achieving that.

How to Save Money on HVAC Inspections

Book a Maintenance Plan

Many HVAC companies offer annual service plans that include inspections, priority booking, and discounts on repairs. These often cost between $250–$400/year and can be more economical in the long run.

Combine With Cleaning

Some technicians offer bundled services (inspection + filter replacement or duct cleaning) at a lower total cost than booking each separately.

Request Multiple Quotes

Always get 2–3 quotes from local HVAC professionals. Ensure they are licensed and insured and provide a breakdown of what’s included.

Avoid Emergency Fees

Regular inspections reduce the likelihood of needing urgent repairs. Emergency call-outs (especially after hours or on weekends) can cost $300–$600+.

Choosing a Reliable HVAC Inspector in Australia

When hiring an HVAC technician, look for the following:

• ARCtick certification: This means the technician is licensed to handle refrigerants in Australia.
• Experience and Reviews: Check Google, ProductReview, or local Facebook groups for recommendations.
• Detailed Reports: Choose companies that offer written inspection summaries.
• Warranties: Some offer service warranties, which show they stand by their work.

You can find qualified technicians on platforms like:

• hipages
• Airtasker
• ServiceSeeking
• Yellow Pages
• Or by asking neighbours and friends

Final Thoughts

In 2025, the average cost of an HVAC inspection in Australia ranges from AUD $150 to $450, depending on your system, property size, and location.
