Quarterly cleaning and filter maintenance is the single highest-leverage practice for parking AC performance and energy efficiency. A clogged cabin air filter alone can increase battery consumption by 20–30% and reduce cooling capacity meaningfully. This guide covers the routine maintenance every driver should perform.

Cabin air filter replacement

Replace cabin air filter every 3 months in normal road conditions; every 1–2 months in heavy dust environments (construction, mining, desert routes). Genuine Vethy filters available through dealer network. Aftermarket filters acceptable if spec-equivalent.

Condenser coil cleaning

External condenser coil benefits from quarterly cleaning. Procedure: power off and disconnect; remove debris with soft brush; gentle low-pressure water rinse from inside-out direction; allow to fully dry before restart. Avoid high-pressure water that can bend fins.

External unit visual inspection

Quarterly visual inspection: mounting hardware tightness, refrigerant line condition, electrical termination quality, paint and surface corrosion, debris in fan or vent area. Address any abnormality through dealer service before it escalates.
