How to Use an Air Conditioning Vacuum Pump

A/C Tips
    Using an air conditioning vacuum pump for your car is key to keeping your A/C system in top shape. This device removes air, moisture, and contaminants from the system before you add refrigerant. This "evacuation" process is crucial for ensuring your A/C runs smoothly and efficiently. Before recharging your car's air conditioning, it's…

What Are AC Evaporators?

A/C Tips
AC evaporators are crucial parts of your car's air conditioning system, usually found inside the passenger compartment under the dashboard. In vehicles with rear air conditioning, there might be two evaporators: one behind the dashboard and another at the rear. The main job of the evaporator is to remove heat and moisture from your vehicle’s…

What Are Expansion Valves?

A/C Tips
What Do Expansion Valves Do? Expansion valves are crucial components in your car's AC system, acting like a faucet for refrigerant flow. They control the amount of refrigerant entering the evaporator based on the temperature. When it's hot, the valve opens more to let in more refrigerant; when it's cooler, it closes to let in…

Air Conditioning Orifice Tubes

A/C Tips
What Do Car AC Orifice Tubes Do? Car AC orifice tubes create a restriction to drop the pressure and temperature (around 30°F) while allowing enough liquid refrigerant to flood the evaporator. It's a fixed device with a specific diameter at the outlet and no control over refrigerant flow. It works with the compressor to maintain…

What Are AC Driers and Accumulators?

A/C Tips
How They Work: Receiver Driers & Accumulators The main job of receiver driers and accumulators in your car's AC system is to store excess refrigerant until it's needed by the evaporator. These components also help remove small amounts of moisture from the refrigerant as it cycles through the system. Inside both receiver driers and accumulators,…

Air Conditioning Pressure Switches

A/C Tips
  Air conditioning systems use pressure switches to manage internal pressure and prevent component failure. Here are some of the most common pressure switches you'll find: Low Pressure Cut Out Switch (LPCO) The LPCO shuts off the compressor if the system pressure drops too low, indicating a lack of refrigerant. It does this by creating…

Understanding High Pressure and Low Pressure in Air Conditioning Systems

A/C Tips
  In your car's A/C system, the compressor is powered by a pulley connected to the engine's crankshaft. The cooling process hinges on creating pressure changes between the condenser and evaporator. When refrigerant enters the evaporator, it absorbs heat from the cabin air, causing it to evaporate and carry the heat away. This refrigerant vapor…
