Split system repairs
Split system air conditioners can develop a range of issues over time. Our team handles all types of split system repair work, from minor faults to full system breakdowns. We regularly fix:
These problems can affect your comfort, increase energy usage, and may be caused by issues such as refrigerant leaks, blocked drainage systems or electrical component faults.
Signs to watch for
Not all issues are obvious right away. Knowing the early signs can help you avoid more serious damage to your system. You may need air conditioning repairs if you notice:
If something doesn't feel right, it's always better to have it checked early.
Heating mode faults
Split system air conditioners don't just cool your home, they also provide heating during cooler months. If your system is not producing warm air, it may be caused by thermostat or sensor issues, refrigerant problems, faults within the reverse cycle system, or airflow restrictions.
In Brisbane, heating may not be used as often, which means problems can go unnoticed until you need it most. If your system isn't heating properly, our technicians can inspect the unit and carry out the necessary repairs to restore both cooling and heating performance.
Electrical crossover diagnosis
Your home's electrical system plays a bigger role in air conditioning performance than many people realise. If your system is not receiving stable power, it can lead to reduced cooling performance, system shutdowns, increased energy consumption and ongoing faults. Older Brisbane homes may also have switchboards or circuits that were not designed for modern air conditioning systems.
Not all air conditioning problems are caused by the unit itself. Common electrical faults include tripped safety switches, faulty wiring or loose connections, damaged capacitors, power supply issues to the outdoor unit, and control board (PCB) failures. These issues can cause your air conditioner to stop working, run inconsistently, or fail to start altogether.
Because Triforce Electrical & Air are qualified electricians as well as air conditioning specialists, we can diagnose both mechanical and electrical faults. This allows us to identify the root cause of the problem and carry out safe, effective repairs, assessing your electrical setup alongside your air conditioning system to make sure everything is working together properly.
When you need reliable split system air conditioning repairs in Brisbane, experience and trust matter. Triforce Electrical & Air is a family-owned Australian business based in Shailer Park, with over 10 years of industry experience across both air conditioning and electrical services. Because we are also qualified electricians, we can identify electrical faults that may be affecting your system's performance — something many air conditioning companies don't look at.
Repair or replace?
Deciding whether to repair or replace your air conditioner depends on several factors. Repairs are usually the best option when the issue is minor, the system is less than 8–10 years old, and the unit is still running efficiently overall. In these cases, a professional repair can restore performance without high cost.
However, replacement may be the better long-term option if your system is breaking down frequently, repair costs are adding up, or the unit is no longer energy efficient. Older systems can also struggle to maintain a comfortable temperature and may use more power than newer models.
At Triforce Electrical & Air, we provide honest advice based on your system and situation. If a repair makes sense, we'll fix it. If a replacement and new installation is the better option, we'll explain why clearly so you can make an informed decision.
Ducted system faults
Ducted systems are complex, and over time, wear and tear can impact performance. Ignoring these faults can lead to uneven cooling, system breakdowns, and costly damage, especially if ductwork or internal components are affected. Our team handles all types of ducted air conditioning repairs, including:
We identify the root cause of the issue and provide reliable repair solutions that improve overall system efficiency.
Ductwork & zoning
Many ducted system problems come down to airflow and ducting issues. We assess:
Fixing these issues not only improves comfort but also increases the efficiency of your air conditioning system.

For Brisbane homeowners, a reliable air conditioning system is essential for maintaining comfort across every room. We repair systems in family homes, multi-room properties, and renovations and upgrades, ensuring your system delivers consistent cooling, improved airflow and better energy efficiency.

Our repair process
We follow a structured repair process to ensure accurate results and long-term performance:
Our goal is to restore your air conditioning system quickly while preventing future issues. In many cases, our technicians can complete repairs on the spot, thanks to fully stocked service vehicles and access to common replacement parts.
Preventative maintenance
Many common air conditioning repairs can be avoided with regular servicing. Over time, dust, dirt and debris can build up inside your air conditioner, reducing airflow, lowering efficiency and placing extra strain on the system. If left unchecked, these small issues can turn into larger faults that require repairs.
Our preventative maintenance and regular air conditioning servicing and cleaning includes system inspections, filter cleaning, airflow testing and electrical checks. Regular servicing helps keep your system running efficiently, improves indoor air quality, reduces the risk of breakdowns and extends the life of your unit.
