Note: Your manufacturer’s warranty may cover the replacement of several AC components, including the compressor. So, before you opt for a replacement, check what your warranty covers.

Is It Worth Replacing the AC Compressor?

Yes, of course!

The AC compressor is vital for pressurizing the refrigerant. If it fails, the AC condenser and evaporator won’t be able to cool your cabin, and eventually, the vents will blow warm air.

Without proper cooling, the humidity in the cabin will increase, which can fog up the mirrors and reduce your visibility. It can also lead to mold growth in the cooling system, which is dangerous for health.

Besides the air conditioning system, a worn compressor can damage your car’s drive belt (serpentine belt), making it loose and slip off. If the belt slips, other engine parts like the power steering pump, alternator, and water pump will stop working too. 

In addition to AC compressor issues, you may also notice a weak car battery, engine overheating, and power steering trouble. 

So, to save your car from major damage, call an auto repair mechanic to replace the bad AC compressor immediately. 

Signs You Need an AC Compressor Replacement

Watch out for these glaring signs that indicate a bad air conditioning compressor: 

  1. Musty smell in the cabin due to mold growth 
  2. Warm air blowing from the vents
  3. Noises from the engine block when the AC is turned on
  4. Refrigerant leak
  5. AC clutch failing to engage
  6. A damaged serpentine belt 
  7. Finding contaminants in the AC system on visual inspection

How Long Do AC Compressors Last? 

Compressors can last about 150,000 to 200,000 miles or 10 to 12 years

However, some factors can damage your compressors faster, such as: 

What Are the Different Types of Car AC Compressors?

Here are some common variants of compressors you’ll find in the market: 

  1. Scroll compressor: Also known as a rotary compressor, this compressor uses interwoven spiral scrolls to compress the refrigerant. It’s widely used in small modern cars. 

  2. Rotary vane compressor: This variant pressurizes the refrigerant using a rotor with movable vanes (blade-like parts). It’s ideal for small to midsize cars. 

  3. Reciprocating compressor: A reciprocating compressor pressurizes the refrigerant using pistons that move up and down. It’s also called a ‘piston compressor’ and is usually used in older heavy-duty vehicles.

Should I Replace the AC Compressor Myself?

No!

To replace the AC compressor, you’ll have to: 

  1. Disconnect your car’s battery to avoid electrical mishaps. 
  2. Remove the drive belt.
  3. Unplug the electrical connectors on the compressor. 
  4. Use a wrench to disconnect the refrigerant hose.
  5. Detach the bad air conditioning compressor.
  6. Install the new compressor.
  7. Refill the system with fresh refrigerant.

These steps can be quite advanced for people with limited car repair experience. Moreover, the refrigerant mentioned above is highly toxic. So, for your well-being, you should seek help from a professional mechanic.
