Vehicle Condensers, Evaporators & Heaters
At MACS Auto, we supply a full range of high-performance vehicle condensers, evaporators, and heaters designed for South African road and climate conditions. Our Heating, Ventilation, and Air-Conditioning (HVAC) components support passenger, commercial, and heavy-duty vehicles, ensuring optimal comfort, performance, and reliability.
Vehicle Condensers
Our condensers function as vital heat exchangers within automotive air-conditioning systems. Positioned in the cooling airflow path, they rapidly cool high-pressure refrigerant gas from the compressor and convert it into a liquid state via condensation. This process transfers excess heat into the ambient air, improving air-conditioning efficiency and extending component life.
We stock a wide range of condensers for all vehicle categories, including passenger cars, bakkies, trucks, buses, and off-road equipment.
Maintenance Tips:
- Replace the condenser when replacing the compressor.
- Do not flush parallel flow condensers.
- Use a fin comb (available from MACS Auto) to straighten external fins and promote airflow.
- Clean the outside of the condenser with a suitable cleaner to improve heat transfer.
Evaporators & Heaters
Our evaporators and vehicle heaters are essential for managing cabin climate across all weather conditions. The evaporator removes heat and moisture from incoming air, working with the expansion valve and blower fan to circulate cool, dehumidified air inside the vehicle. In contrast, the heater core uses heat from the engine coolant to deliver warm airflow during colder months.
We offer vehicle-specific and universal evaporators and heaters for a wide range of makes and models.
Best Practices:
- Always replace expansion valves, orifice tubes, and driers when the air-conditioning system is opened.
- Evaporators cannot be flushed.
- Ensure the expansion valve’s tonnage and superheat rating match the original.
We also supply essential HVAC system components, including solenoid valves, thermostats, pressure switches, relays, hoses, and fittings.
