What Is Automotive Refrigerant Gas?
Refrigerant gas is a specialised fluid that cycles between liquid and gas states within your vehicle’s air-conditioning (A/C) system. It absorbs heat from the cabin and releases it outside, producing the cool, refreshing air that makes driving comfortable. Choosing the correct refrigerant and maintaining the right charge levels ensures optimal AC efficiency and long-term performance.
The Role of A/C Compressor Oil
Compressor oil lubricates the moving parts inside your vehicle’s A/C compressor, reducing friction, preventing wear, and protecting against costly breakdowns. Without this vital oil, the compressor can seize, leading to system failure.
MACS Auto stocks a full range of high-performance compressor oils tailored to different refrigerant types, ensuring smooth operation in all weather conditions.
Why Refrigerant Maintenance Matters
Over time, refrigerant gas can leak or degrade, reducing cooling performance. Common symptoms of low refrigerant include:
- Weak airflow or warm air from vents
- AC system cycling on and off
- Unusual noises or smells
Regular A/C maintenance, including leak detection, recharging, and oil top-ups, keeps your system running efficiently. Our products are trusted by qualified technicians and workshops across the country.
