my Skoda Octavia NFL (2020-Present) AC is not cooling properly, what’s the problem?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to ensure safety while working on electrical components.

2. Recharge Refrigerant

• Tools Required: Manifold gauge set, refrigerant canister, safety glasses, gloves.
• Connect the manifold gauge set to the low-pressure and high-pressure service ports.
• Start the engine and set the A/C to maximum cool.
• Check the pressure readings:
  • If low, add refrigerant according to manufacturer specifications (typically R-134a or R-1234yf).
  • Monitor pressure while adding refrigerant until it reaches the optimal range.

3. Inspect and Replace Components

• Tools Required: Socket set, torque wrench, screwdrivers.
• If the compressor is not engaging, inspect the electrical connectors and fuses. Replace any blown fuses.
• If the compressor is damaged, remove it:
  • Disconnect the electrical connector and discharge line.
  • Unbolt the compressor from its mounting bracket.
  • Install the new compressor and reconnect the lines.
  • Torque bolts to manufacturer specifications.

4. Replace Cabin Air Filter

• Tools Required: Screwdriver (if necessary).
• Locate the cabin air filter housing, usually behind the glove compartment.
• Remove the old filter and inspect for debris and blockages.
• Install a new cabin air filter and ensure it is seated properly.

5. Test A/C System

• Reconnect the battery and start the vehicle.
• Set the A/C to maximum cool and check for cold air coming from the vents.
• Observe the A/C system operation to ensure it cycles properly without excessive noise.
