If you try to blast cool air in your car and all you get is hot air, then there could be a technical break down with your car’s AC system. Earlier than seeking out a car air conditioning repair service, you need to understand a little about the inner workings of the AC’s cooling system. The Air Conditioning system consists of four major components. First of all, the compressor condenses refrigerant gasses. After that, an evaporator gets heat from the air and passes it all the way through the refrigerant agent. Subsequently, the heat boils off the water vapors, decreasing the overall humidity and temperature levels in the motor vehicle. The condenser also plays an important role. Its key function is to maintain the refrigerant cool by transferring the heat from the gasses in the compressor to extremely pressurized liquid. The ultimate component is the expansion valve, and it transfers the liquid refrigerant from the condenser into a lesser pressure liquid for entrance into th...
