Car and Truck Air Conditioning repair Chicago
Where does the cold air come from? Where to get Air Conditioning repair Chicago? Why does my cars Air Conditioning blow warm air? Why not ask the air conditioning repair to the specialists in Chicago? Modern Air conditioning systems use refrigerant to absorb heat. The refrigerant absorbs heat from the interior of a vehicle in a component called the evaporator. Air is pushed across the evaporator. Since the evaporator is colder then the air coming across it the heat is absorbed by the refrigerant, resulting in cold air being blown into the passenger compartment.

This air is really the same air but has the heat removed or absorbed. The heat that was absorbed is now absorbed in the refrigerant. The Air conditioning compressor pumping the refrigerant is moved to the air conditioning condenser. The condenser’s job is to dissipate the heat. The compressor has increased our pressure. We have an enormous amount of heat loss across the face of the condenser. As the refrigerant is pushed across the condenser it sheds the absorbed heat from the passenger compartment.
The refrigerant still under high pressure, and with heat removed the refrigerant is now ready to absorb heat again. The refrigerant is then pushed thru a small orifice called a “orifice tube” or expansion block which drops the pressure in the Air conditioning repair system. Once the pressure is reduced it is pushed thru the evaporator again to absorb heat again from the passenger compartment. The air conditioning compressor is the hardest working component of the air conditioning system. The traditional design consists of pistons and valves. Other styles include vanes and some are a scroll type air conditioning compressor.
Considerable heat is generated by a compressor, and the cold refrigerant returning to the compressor is vital to its longevity. If an air conditioning system is not full to capacity. The compressor is not receiving enough cold refrigerant and oil, and overheating of moving parts, seals is occurring, and a shortened compressor life is inevitable.
The air conditioning condenser receives high pressure refrigerant from the air conditioning compressor. A series of small tubes allows heat energy contained in the refrigerant to transfer to the condenser, and on to the air rushing thru the condenser. The condenser is located in front of the radiator in front of the vehicle in order to allow maximum amount of air flow. In the air conditioning condenser the refrigerant is both a gas and a liquid. As the refrigerant enters the condenser it is very hot, high pressure gas. As the gas passes thru the condenser, sufficient cooling allows the hot gas to condense and turn into a liquid by the time it leaves the condenser. An enormous amount of heat is shed in this process.
The expansion valve has one job, and that’s to drop the pressure. The pressure can be 250-300 psi are common and by the time the refrigerant passes thru the valve they will drop to 20-30 psi. This drastic pressure drop allows the refrigerant to be very cold and ready to absorb heat.
The evaporator receives cold low pressure refrigerant from the expansion valve. This allows heat absorption. In the evaporator the hot air from the evaporator there is enough heat in the air to boil the refrigerant. An enormous amount of heat energy is absorbed this way. As the refrigerant leaves the evaporator, it is transformed almost completely to a gas.
The air conditioning drier, as heat load increases or decreases , the refrigerant expands or contracts. The drier allows this to happen in this space. Located inside the drier are fabric pouches that contain silicon beads that absorb moisture.
The rest of the air conditioning system is made up of hoses, pipes, wiring, switches, modules, motors, fans, doors, actuators, and refrigerant. All vehicles have most of these additional items. The air conditioning systems are getting more and more complex as vehicles are getting more efficient. Car and truck repair in Chicago has been our specialty since 1966.
