🧰 We Repair All Mitsubishi Heavy Industries Systems

Our technicians are trained and experienced across the full MHI range, including:

• Split system air conditioners
• Multi-split systems

We use manufacturer-approved diagnostic tools to locate faults quickly — from refrigerant issues to PCB failures — ensuring your repair is done right the first time.

🏠 Residential MHI Air Conditioner Repairs

If your home’s MHI air conditioner isn’t cooling or heating effectively, it could be a simple fault — or a sign of deeper issues. Common residential repair calls include:

• Unit not starting or blowing warm air
• Flashing error codes on display
• Strange noises or smells
• Leaking water or refrigerant
• Poor airflow from vents

Our technicians not only repair the fault but also inspect for hidden wear or buildup that could shorten your system’s lifespan. We’ll advise if your system needs a preventative service to reduce future breakdowns and improve energy efficiency.

⚠️ Don’t Ignore Fault Codes or Try DIY Fixes

When a Mitsubishi Heavy Industries system displays a fault code, it’s alerting you to an internal issue. These codes can be ambiguous, and simply resetting the system can hide the real problem — leading to more serious damage like compressor or circuit board failure.

DIY repairs or internet fixes often cause more harm than good. Instead, call our certified technicians. We’ll safely diagnose the issue and repair it before it escalates into a costly replacement.
