Fast Diagnostics for Cooling Issues

Is your air conditioning unit blowing warm air, or is the airflow too weak to cool down the room? In Singapore's tropical climate, a non-cooling aircon can make your living and working spaces unbearable. Cooling problems are typically linked to low refrigerant gas, faulty capacitors, blocked condenser coils, or bad compressor parts.

NEXGEN's technicians run deep diagnostic checks on your system's electrical circuits, fan speed motors, compressor starters, and pressure lines. We locate the root cause of the warm air or weak flow and repair it quickly to restore your indoor comfort.

Our Scope of Work

We test and analyze your system to restore full cooling power using the following methods:

Measure and verify wind velocity and airflow output
Test compressor start-up capacitor and overload protector
Check evaporator and condenser coil cleanlines and heat transfer
Diagnose fan motor wind speed and capacitor health
Check refrigerant pressure levels for leak indicators
Calibrate thermostat settings and remote control sensors

Frequently Asked Questions

Learn more about common cooling problems and how we resolve them:

  • Why is my aircon running but not blowing cold air?
    This is often caused by dirty air filters blocking airflow, low refrigerant levels, a broken fan motor, or a failed compressor capacitor that prevents the cooling cycle from starting.
  • How long does it take to diagnose a cooling issue?
    A standard diagnostic check takes about 30 to 45 minutes. Our technician will test all major parts and explain the issue to you along with a repair quote.
  • Is warm air always a sign of a gas leak?
    Not necessarily. It can also be due to a faulty thermostat sensor, a blown capacitor, or blocked condenser coils that are failing to release heat outdoors.
