Ducted Aircon Leak Solutions in Griffin
Ducted Aircon Leak Solutions in Griffin
Is there anything more frustrating than turning on your air conditioning during a humid Queensland afternoon, only to realise it’s barely blowing cool air? For many homeowners, a system that isn’t performing correctly isn’t just an inconvenience—it’s a sign that something is wrong under the hood.
Recently, Fallon Solutions visited a local resident in Griffin to investigate a struggling ducted system. What started as a routine part replacement quickly turned into a detailed HVAC leak detection mission, highlighting why professional diagnosis is vital for long-term comfort.
The Problem: Signs of a Ducted Aircon Leak
The customer in Griffin noticed their ducted system wasn’t cooling the home effectively. While many people assume a lack of cooling simply means the system is “old,” there are often specific mechanical failures at play.
Common symptoms of a ducted aircon leak or system failure include:
- Reduced Cooling Capacity: The air coming from the vents feels lukewarm despite the thermostat being set low.
- Short Cycling: The outdoor unit turns on and off frequently.
- Hissing Noises: Unusual sounds coming from the indoor or outdoor components.
- Increased Energy Bills: The system works twice as hard to reach the set temperature, spiking your electricity costs.
In this specific case, the unit was struggling significantly, suggesting that the refrigerant—the “lifeblood” of the air conditioner—wasn’t at the level it should be.
The Solution: Expert HVAC Leak Detection
When our technician arrived on-site in Griffin, the initial plan was to fit a new Electronic Expansion Valve (EV) body to the outdoor unit. However, as part of our commitment to doing the job right, we performed a deeper investigation.
Here is how we handled the Daikin service:
- Safety First: We isolated the power to the unit to ensure a safe working environment.
- Refrigerant Recovery: To work on the internal components, we had to “reclaim” the gas. This is a process where we safely pump the refrigerant out of the system into a storage cylinder.
- The Discovery: This is where the technical expertise pays off. The system was supposed to hold 4.6 kg of refrigerant, but we only recovered 1.6 kg.
- Accurate Diagnosis: Finding only a third of the required gas confirmed that the system had a significant leak. Without this step, simply replacing a part would have been a “band-aid” fix that wouldn’t have solved the underlying issue.
Because the system was older, we provided the customer with several professional pathways. We quoted for a formal pressure test to locate the exact source of the leak, but we also provided options for the future: a quote for a full replacement with a modern Daikin model, and an alternative quote to install individual split systems in the bedrooms.

The Benefits for the Homeowner
By choosing a thorough investigation over a quick fix, the homeowner gained several key advantages:
- Informed Decision Making: Rather than spending money on a repair that might not be cost-effective for an old unit, the customer now has all the figures to decide between a repair or a brand-new, more efficient system.
- Energy Efficiency: A system with a leak is an energy hog. Resolving the leak or upgrading the unit will significantly lower quarterly power bills.
- Long-Term Reliability: By considering a new Daikin replacement, the homeowner can enjoy years of “set and forget” comfort without the fear of another breakdown.
- Property Value: High-quality, functional climate control is a major selling point for homes in the North Brisbane area.
