HVAC Components

The HVAC system in your vehicle is complex. When you need auto AC repair, you must replace several parts as they become contaminated. 

Auto AC Parts

The various parts of an auto air conditioning system include:

Air Compressor:

Compresses refrigerant to raise its temperature and cycles it through the system.

Receiver/Dryer:

A storage tank for extra refrigerant. It also has a filter and desiccant material to remove moisture and other impurities.

Condenser:

It cools the hot refrigerant by transferring the heat to the outside air.

Flow Control Devices (orifice tube or expansion block):

They control refrigerant flow to the evaporator.

Evaporator:

The air is blown through the evaporator, which absorbs the heat and boils the refrigerant to a vapour state.

Air Distribution System:

Includes the blower fans, air ducts, and airflow control valves.

Cabin Air Filters:

Keep the air clean from dust and soot particles found in the air in the vehicle’s interior.

Other Components:

Include high and low-pressure lines, tubes, control sensors, and pressure control devices.

Auto Heater Parts

The heating part of the HVAC system is not as complicated as the air conditioning side. The components include:

Heater fan:

Blows the heat into the cabin.

Water pump:

Pumps water through the engine to keep it cool.

Thermostat:

For most vehicles, the thermostat will open at around 195 degrees to allow coolant to flow through the radiator to cool off so the vehicle doesn’t overheat.

Blower motor:

Blows hot air from the hot coolant or cool air from the refrigerant through the HVAC system.

Heater Core:

Radiates the heat from the hot coolant past the blower fan to heat the cabin’s interior.

Heater hoses:

Carries coolant in a cycle from the engine to the radiator and heating system and back to the engine.

Any parts in your vehicle’s HVAC system could break at any time, though they are—for the most part—known to last for many years. While they are referred to as one system, if the heat breaks, you will most likely still have air conditioning and vice versa.
