Heating & Air Conditioning Systems

Is the air conditioner or heater in your vehicle not working? If you’re experiencing any of these symptoms there may be an issue with your HVAC system:

·         Low airflow or inconsistent temperatures

·         Fogging on the windshield during defrosting

·         Growling, squealing, or grinding noise during A/C or heater operation

·         Engine overheating

The Heating, Ventilation, and Air Conditioning System in your vehicle is a complicated system made up of several essential components.

Air Conditioner Components:

·         A/C Compressor

Contains refrigerant pump and control valves for A/C pressure

·         Condenser

Helps transfer heat from the passenger compartment to under the hood

·         Radiator Fan

Removes heat from the radiator and condenser processes

·         Dryer or Accumulator/Receiver

Responsible for storing refrigerant and removing moisture

·         Blower Fan

Moves air through evaporator and heater core

·         Expansion Valve

Controls pressure differentials, which helps refrigerant reduce heat from the passenger compartment

·         Evaporator

Assists in moving heat from passenger department to condenser

·         Refrigerant

Substance that can be condensed and vaporized in certain temperatures

Heater Components

·         Radiator

Helps transfer heat from the coolant to the outside of the vehicle

·         Radiator/Heater Hoses

Transfers coolant to the heating core

·         Blower Fan

Helps move air from inside of the vehicle to evaporator and heater core

·         Thermostat

Responsible for regulating the flow of coolant

·         Heater Core/Control Valve

Assists in maintaining proper passenger area temperature

Having a properly functioning HVAC system is not only important for the comfort of you and your family, but also for your safety.  If one of the components in these systems isn’t working it may result in reduced driving visibility, as windshields tend to fog and freeze.  If you are experiencing any issues with your heating or air conditioning system in your car or truck, bring it to Rydell’s Service Center for a diagnosis.
