How It Works
Our Working Process
From booking to completion — a simple, transparent process designed around you.
01
AC Inspection & Diagnosis
Our certified technicians perform a comprehensive check of your aircon unit — including refrigerant pressure, electrical components, and overall cooling performance — to accurately identify the root cause of any issue.
02
Deep Cleaning & Servicing
We thoroughly clean filters, coils, fan blades, and drainage pipes. For heavily clogged units, we recommend chemical wash or chemical overhaul to restore optimal airflow and cooling efficiency.
03
Repair & Parts Replacement
From faulty PCB boards and capacitors to fan motors and sensors, we replace damaged components with high-quality parts, ensuring your aircon functions like new.
04
Gas Top-Up & Leak Fix
If cooling is weak due to low refrigerant, we detect and repair leaks before topping up gas to manufacturer-recommended levels for long-lasting performance.
05
Testing & 24/7 Support
We run thorough performance tests to verify cooling, airflow, and safety. Our round-the-clock support ensures you're never left without help during an emergency.
