What are the dangers to the car from too little refrigerant?  

Not having enough refrigerant in a car’s air conditioning system can lead to serious risks for the vehicle. Here are some of the most important ones:

Decrease in air conditioning performance: not having enough refrigerant in the system can lead to a decrease in air conditioning performance, which means the car cabin will cool less effectively.

Compressor damage: not having enough refrigerant in the system can lead to damage to the A/C compressor, which means it needs to be replaced or repaired.

Damage to the cooling system: lack of sufficient refrigerant can lead to insufficient cooling of the car’s cooling system, which in turn can lead to overheating of the engine and damage to its components.

Increased fuel consumption: not having enough refrigerant in the air conditioning system can lead to an increase in fuel consumption, as the engine will have to work harder to reach the right temperature.

Summary

In summary, not having enough refrigerant in the car’s air conditioning system can lead to serious risks for the vehicle, such as a decrease in air conditioning performance, compressor damage, cooling system damage and an increase in fuel consumption. Therefore, it is essential to regularly refill the refrigerant in the system to ensure its proper operation.
