High summer temperatures make car air conditioning essential for comfort and safety. However, improper use can lead to problems such as bad smells, humidity, and costly breakdowns.
According to a mechanic, the most frequent error that can damage the system is turning off the engine with the air conditioning (A/C) still active. When the compressor is running, condensation forms in the evaporator, a key component of the circuit. If the engine is abruptly stopped, this moisture can remain trapped, promoting the proliferation of bacteria, mold, and consequently, bad odors and reduced system performance.
The advice to prevent these issues is simple: a few seconds before turning off the vehicle, deactivate only the A/C compressor button, leaving the fan running. This airflow helps dry the accumulated moisture in the evaporator, a preventive habit that can extend the lifespan of the climate control system and avoid additional expenses for cleaning or repairs.
Keeping the air conditioning in good condition not only improves comfort but also contributes to safer driving and breathing cleaner air inside the vehicle. Nevertheless, if the system does not cool properly, makes strange noises, or maintains persistent odors, it is advisable to visit a specialized workshop.
