Measuring Your AC System's True Output
While a regas might restore some cooling, Performance Testing verifies that every component—from the compressor to the vents—is working in harmony. This detailed check determines the efficiency and cooling capacity of your system against manufacturer specifications.
This is especially important in the hot Pretoria climate, where your AC system is constantly put under stress. We replicate various operating conditions to ensure your car AC doesn't just work, but performs optimally when you need it most, such as in heavy traffic or at high ambient temperatures.
Key Performance Metrics We Test
Our comprehensive testing routine involves measuring several critical parameters to ensure peak functionality:
- Vent Temperature: The primary measure, ensuring the air is consistently cold enough (usually below 10°C).
- High & Low Side Pressures: Measured using precise manifold gauges to confirm the compressor is pumping correctly and there are no internal blockages.
- Airflow Volume: Checking that the blower motor and air ducts are delivering sufficient air volume into the cabin.
- Clutch Cycle Time: Analysing the frequency of the compressor clutch engagement to spot signs of overworking or electrical issues.
If the performance test reveals issues, we provide a detailed report outlining whether the fault lies in low refrigerant, internal blockages (like a clogged expansion valve or condenser), or mechanical failure. Trust our Pretoria specialists to give you an accurate assessment of your car AC's health.
