Heating & Air Conditioning Systems

Heating, Ventilation, and Air Conditioning System (HVAC)

Grand Forks’ climate can be unpredictable. 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 air flow or inconsistent temperatures
  • Fogging on windshield durring defrosting
  • Growling, squealing or grinding noise during A/C or heater operation
  • Engine overheating

The Heating, Ventilation, and Air Conditioning Sytem in your vehicle is a complicated system made of 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 condeser 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 condeser
  • Refrigerant
    • Substance that can be condensed and vaporized in certain temperatures

Heater Compnents

  • Radiator
    • Helps transfer heat from coolant to the outside of the vehicle
  • Radiator/Heater Hoses
    • Transfers coolant to the heating core
  • Blower Fan

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 into Rydell's Service Center for a diagnosis.

How can I avoid losing the A/C or heat in my vehicle?

Hot summers and cold winters can take a toll on your vehicle, especially with North Dakota's extreme weather changes.  The HVAC system contains important components of your vehicle that require regular maintenance, much like other systems in your car, truck or SUV.  There are several components in this system that can be susceptible to breaking down throughout the lifespan of your vehicle.  Have your HVAC system checked periodically by getting routine inspections on your car, truck or SUV. Our knowledgeable service writers and technicians work hard to make sure you're safe and comfortable in any weather.  Schedule an appoinment online, or call us today at 701-772-7211.
