Drivers cautioned against turning on car A/C immediately and running on low fuel

Experts warn that activating a vehicle’s air‑conditioning system as soon as the engine starts puts sudden stress on the compressor, shortens its lifespan and can lead to costly repairs. They recommend waiting at least 30 seconds before turning on the A/C and increasing cooling intensity gradually after opening doors to vent hot air. Brief use of the recirculation function helps cool the cabin faster, but should not be left on for long periods to avoid excess humidity.

The same specialists note that a weak battery can impair the A/C’s performance, so regular battery checks are advised. Clean ventilation openings and filters are essential for proper airflow and to prevent bacterial growth. For very short trips, opening a window may be more efficient than using the A/C. Additionally, driving with less than one‑quarter of the fuel tank can cause the fuel pump to overheat and accelerate wear, increasing the risk of corrosion and failure. Keeping the tank above the quarter‑tank level helps avoid these issues.
