How Your Car’s A/C System Works

Your vehicle’s air conditioning system doesn’t just blow cold air—it uses a combination of mechanical and chemical processes to remove heat from the cabin. Here’s how it works:

Compressor: Pressurizes the refrigerant and moves it through the system.
Condenser: Cools the hot refrigerant gas and turns it into a liquid.
Receiver-Drier or Accumulator: Filters out moisture and debris.
Expansion Valve or Orifice Tube: Controls the flow of refrigerant into the evaporator.
Evaporator Core: Absorbs heat from the inside of your car and cools the air.

When each component is working properly, your A/C delivers cool, refreshing air all summer long.

Why Your Car or Truck A/C Might Stop Working

If your air conditioner isn’t performing like it used to—or not at all—there are several common culprits we frequently see in our Lindon auto shop:

Low Refrigerant: Caused by leaks. Not enough refrigerant = not enough cooling.
Compressor Problems: Can wear out over time or fail due to lack of lubrication.
Leaky Hoses or Fittings: Let refrigerant escape, decreasing system performance.
Blocked or Dirty Condenser: Stops the refrigerant from cooling down properly.
Bad Sensors or Switches: Electrical issues can prevent your system from turning on.
Moldy or Dirty Evaporator: Reduces airflow and causes foul smells.
