Leaving the system off for months dries out parts, blocks the compressor and can cause losses of up to R$3,000 in the mechanic shop
Many drivers believe that car air conditioning should be completely forgotten as soon as the thermometers register the first drops in temperature. This false sense of fuel economy hides a silent and very expensive mechanical trap.
In practice, knowing Why is it important to turn on your car’s air conditioning even on cold winter days? It’s the main difference between low-cost routine maintenance and having to replace the heart of the system during the next heat wave.
What happens when the system is turned off for months
To understand the size of the problem, it is necessary to abandon the idea that the equipment is only used to cool the cabin. The air conditioning network works as a closed circuit and depends on continuous movement to stay healthy.
Refrigerant gas does not travel alone. He travels through the pipes carrying a specific lubricating oil for moving parts. When the owner spends the entire autumn and winter without touching the activation button, this oil stops circulating and ends up settling at the bottom of the reservoir.
The immediate result of long inactivity is the drying out of sealing rubbers and small hoses. With the insulation compromised, the fluid leaks without making a fuss. The aggravating factor occurs up front: the compressor, the most important part of the structure, loses its protective layer. When finally required at the arrival of spring, the internal friction between metals without oil can permanently lock components.
Clean visibility and mite-free cabin
In addition to preventing the mechanical part from suffering premature wear, maintaining the habit of activating refrigerated ventilation directly affects the your safety in road traffic.
On cold, rainy or foggy days, the windows quickly close and fog up due to the thermal difference between the human body and the outside temperature. The vehicle system operates as a powerful cabin air dehumidifier. It removes all moisture from the passenger compartment and returns visibility to the driver in a few seconds, with an efficiency that a conventional defroster cannot deliver.
Another hidden gain appears in your family’s respiratory health. Weekly operation prevents the accumulation of fungi and bacteria in the curves of plastic ducts, eliminating that classic bad smell of damp cloth that invades the car when the equipment spends months dormant.
The trick of mixing air conditioning with hot air
Most drivers avoid this feature because they don’t want to freeze their arms and face first thing in the morning. The way out of this climate dilemma is activate the refrigeration together with the heater.
The hot air button does not cancel the compressor operation. The mechanism will continue to push the gas, spreading oil through the pipes and wiping moisture from the air, while the engine heat returns a pleasant breeze and comfortable for everyone on board.
The salty bill at the auto repair shop
The classic excuse for those who travel with the windows closed and the dashboard off is to save gas. The reality of the workshop accounts, however, shows that the wear caused by lack of activation tramples on any savings at the fuel pumps.
If you use the device weekly, the cost of a preventive check at a specialized store — which involves refilling fluids, cleaning and changing the cabin filter — varies between R$200 and R$400 on the national average.
On the other hand, if the lack of prolonged lubrication causes the compressor to freeze, the bill changes. Reconditioned parts and deep cleaning of machinery rarely cost less than R$600, while installation of a zero kilometer compressor it jumps to the range of R$1,000 to R$3,000, fluctuating a lot depending on the brand of vehicle. By putting at the tip of the pencil the extra labor costs to carry out this more invasive change, which fluctuate around R$300 to R$600the repair becomes a drain on money.
To ensure that the set survives the change of seasons with a top rating, workshops recommend turning on the air conditioning at least once a weekrunning for 10 to 15 minutes. It’s a short break on the way to the bakery or work that saves mechanics, protects your bank account and offers maximum security in the rear-view mirror.
