While some aftermarket parts may be compatible, it is recommended to use Hyundai-approved components to ensure proper functionality and avoid potential issues. Always verify compatibility with your specific model year and consult a professional if unsure.

Regular maintenance for the HVAC system includes checking and replacing the cabin air filter every 12,000 to 15,000 miles, inspecting refrigerant levels, and ensuring the blower motor and condenser are functioning properly. Additionally, have the system professionally inspected annually to address any potential leaks or malfunctions and maintain optimal performance.

Open the glove box, remove the retaining clips, and carefully pull out the old filter. Insert the new filter, ensuring it is properly aligned, and reassemble the glove box. Refer to the owner’s manual for detailed instructions and safety precautions.

If the HVAC system is not blowing cold air, first check the refrigerant levels and look for leaks. Inspect the compressor and ensure it is functioning properly. If the issue persists, it may be due to a faulty blower motor, clogged condenser, or electrical problem. Consult a certified technician for a thorough diagnosis and repair.

To optimize HVAC performance, regularly replace the cabin air filter, ensure refrigerant levels are correct, and clean the condenser and evaporator coils. Use the recirculation mode to reduce strain on the system and avoid setting the temperature to extreme levels. Schedule annual inspections to address any issues early and maintain efficient operation.
