Auto Air Conditioning Repair in Rockwall, TX
How do my car’s air conditioning and heating systems work?
We take advantage of the fact that we can stay warm in our cars during Heath winters and cool during Royse City summers, but our vehicles’ air conditioning and heating systems are fairly complex. Your vehicle’s air conditioning system does not create cold air. Rather, it takes the heat and moisture out of the air in your car and leaves behind the cooler air. To heat up your car, hot engine coolant is circulated through a small radiator, which is often called a heater core. There is a fan in front of the heater core to blow cool air to blow cold outside air over the fins. As this air travels through the heater core, it heats up and this is the warm air that blows out of your heater vents.
Your vehicle’s air conditioning system includes the condenser, compressor, expansion valve, and evaporator. Refrigerant or coolant is compressed in the compressor and turns into a hot gas. This hot gas is cooled into a liquid state in the condenser, which is similar to a small radiator, then travels to the expansion valve. In the expansion valve, also called the orifice tube, the refrigerant turns back into a gas and rapidly cools in the evaporator, entering the low-pressure side of the air conditioning system. The receiver contains a desiccant bag to remove and collect unwanted moisture/water and impurities. A fan blows over the evaporator and cools the air that blows out of your vents. Now that the refrigerant is in a gaseous state, it can absorb heat from the air passing through the evaporator fins. The refrigerant then travels back to the compressor through the suction hose of the air conditioning system to get compressed back into a high-pressure gas and begin the process again.
If any parts of your vehicle’s heating or air conditioning systems are damaged, it can affect the entire system. If you sense a problem, feel free to bring your car or truck to Horizon Auto Center in Rockwall today.
