R134a Freon AC Repair

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 Westminster, Colorado winters and cool during Arvada, Colorado summers, but our vehicles' air conditioning and heating systems are fairly complex. 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, then travels to the expansion valve. In the expansion valve, the refrigerant turns back into a gas and rapidly cools in the evaporator. A fan blows over the evaporator and cools the air that blows out of your vents. If any parts of your vehicle's heating or air conditioning systems are damaged, it can affect the entire system.
