  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…

  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…

  Car AC clutch failures can happen for various reasons. It's crucial to identify the exact cause to fix the problem properly. Typically, clutch failure is due to high pressure, voltage issues, or both. How to Check for Car AC Clutch Failure: Check the Refrigerant Level: If the refrigerant charge is off, the pressure switches…

Don’t just swap out the compressor — figure out why it failed in the first place, so it does not happen again Compressor failures usually happen because something else in the A/C system went wrong. This could be due to low refrigerant, issues with the electronic fan or fan clutch, a clogged condenser, voltage problems,…

  The right type and amount of oil are crucial for your A/C system's performance. Always check the manufacturer specifications, usually found on the under-hood decal, for oil and refrigerant charge details.   Why Oil is Essential for Your A/C System: Lubrication: The A/C compressor needs oil to reduce friction and prevent metal-to-metal contact. Proper…

Most modern vehicles use parallel flow style a/c condensers. Leading aftermarket suppliers have also updated original serpentine and piccolo air conditioning condenser styles to more efficient parallel flow replacements. Keep in mind, the refrigerant charge can vary based on condenser design, so you might need to adjust it if you're swapping a factory condenser for…
