4 steps to diagnose a car aircon compressor problem

4 steps to diagnose a car aircon compressor problem

If your car's airconditioning compressor fails, it may not be able to cool the car properly. A failed compressor could also cause other problems with your car's electrical system. If you notice any of the following signs that your car's airconditioning compressor is failing, take it to a mechanic as soon as possible: reduced air flow from the vents, an unusual smell from the AC unit, or warning lights on the dashboard.

4 steps to diagnose a car aircon compressor problem:

 

Step 1: With the engine running, turn on the A/C onto high. 

 

This will cause the car air con to start up, activating the aircon compressor.

 

The car aircon compressor will suck refrigerant in from the evaporator under low pressure, compress the refrigerant and forward it to the condenser under high temperature and high pressure.

 

Step 2: Listen for any unusual noises.

 

Unusual noises can arise in a number of ways, so check the following before concluding that you need a new car air con compressor.

 

Check the clamps and fixing points for breaks, cracks and any missing nuts or bolts.

Check the hoses and lines to determine if vibrations from the engine are being transmitted to the cabin. Hold each line with one hand to see if it eliminates the suspicious noise.

The car aircon compressor is driven by a belt. If the belt, clamping device, tensioner pulleys, or clutch are worn, they could cause unusual noises.

If none of these are causing the unusual noise, it’s best to get the vehicle checked out by a Natrad technician. The noise could be caused by excessive high pressure in the system or contamination of the air conditioner refrigerant. These issues need to be diagnosed by a licensed air con technician.

Step 3: Check to see if cool air comes from the air vents.

 

If there isn’t cool air coming from the vents, there are a few checks you can start with to rule out a compressor issue:

 

Check that the cooling fans are running when the air conditioner is on.

Make sure the cabin air filter isn’t clogged.

Ensure there isn’t a build-up of leaves, bugs, or dirt preventing airflow through the condenser.

 

Step 4: Check for a visible leak under the car.

 

If you do have a leak or you rule out the above possible issues, you’ll need to take your vehicle to a licensed repair technician who will test the system to diagnose the problem.

 

 

If you're experiencing issues with your car's air conditioning, there's a good chance that the compressor is to blame. Compressors can wear out over time, and when that happens, they can't produce enough air to keep your car cool. If you notice that your car's air conditioning isn't working as well as it used to, or if it's not cooling your car at all, it's probably time to take it in for a check.
