Repair or Replace: What’s Best for Your Car’s AC Compressor?

While a broken AC compressor can be repaired, replacement is often the better option

Why?

Compressors are complex components with many moving parts, and their failures usually involve extensive internal damage. So, a car AC compressor repair would require a complete teardown and rebuild of the old compressor, which isn’t practical or cost-effective. Plus, there’s no guarantee that the AC compressor issues won’t return.

Getting a complete replacement is more economical for a car owner in the long term. 

That said, there are a couple of factors to consider while deciding whether to repair or replace the broken AC compressor. These include:

Is It Worth Replacing the Car AC Compressor?

Yes, absolutely. 

The air conditioning compressor pressurizes the refrigerant, enabling the condenser and evaporator to cool your cabin. If it fails, AC vents will blow warm air, increasing cabin humidity and mold growth. 

A failing compressor can also damage the serpentine belt, causing it to slip. This will disable other components run by the belt, like the power steering pump, alternator, and water pump. Consequently, it can lead to issues like a weak battery, engine overheating, and power steering pump failure.

To prevent further damage, have an AC technician replace the faulty compressor promptly.

7 Signs You Need an AC Compressor Replacement

Watch out for these symptoms of a bad air conditioning compressor: 

  1. Musty smell in the cabin due to mold growth 
  2. Warm air blowing from the vents
  3. Strange noises from the engine block when the AC is on
  4. Refrigerant leak
  5. AC compressor clutch failing to engage
  6. A damaged serpentine belt 
  7. Contaminants in the AC unit

How Long Do AC Compressors Last?

Compressors can last about 150,000 to 200,000 miles or 10 to 20 years.

However, some factors can damage compressors in the AC unit faster, such as: 

How to Prolong the Life of Your Car’s AC Compressor?

These tips can help keep your compressor running smoothly, preventing the need for AC repair:

Can You Replace the AC Compressor Yourself?

It’s best to avoid DIY and leave compressor replacement to a trained professional if you lack car AC repair experience.

Here’s how your car repair mechanic or Heating, Ventilation, and Air Conditioning technician (HVAC technician) will replace the air conditioner compressor:

  1. Disconnect the car battery to avoid electrical mishaps.
  1. Locate the air conditioning compressor and remove the serpentine belt from the compressor’s pulley. They may need to loosen other belts to access it.
  1. Carefully unplug the electrical connector on the bad AC compressor.
  1. Disconnect refrigerant lines from the faulty AC compressor. Your HVAC mechanic will cap these lines to prevent contaminants from entering the AC system.
  1. Unfasten the bolts that hold the compressor and carefully lift it out of the vehicle.
  1. Place the replacement part (new compressor), reattach the bolts, and connect the refrigerant lines. Then they’ll plug in the electrical connector and reattach the serpentine belt. They’ll use new seals at every connection to avoid leaks.
  1. Finally, they’ll run a quick test to confirm your vehicle’s AC compressor and the entire AC unit is functional. They’ll ensure there’s no other AC problem or unusual noises.

3 FAQs on Car AC Compressors

Here are the answers to some common queries to clarify your doubts about AC compressors:

1. What Is a Car AC Compressor and How Does It Work?

The AC compressor is a pump that pressurizes and circulates refrigerant gas to cool your car’s interior. Powered by a drive belt and pulley system, it engages via an electromagnetic clutch when the air conditioner is turned on.

It compresses the refrigerant into a high-pressure gas and sends it to the condenser, which cools and changes the refrigerant gas to liquid. This liquid refrigerant moves to the evaporator coil, absorbing cabin heat and releasing cold air into your car’s interior.

2. What Are the Different Types of Car AC Compressors?

Some common variants of compressors include:

  1. Scroll or rotary compressor: This AC compressor type uses interwoven spiral scrolls to compress the refrigerant and is widely used in small cars. 
  1. Rotary vane compressor: It pressurizes the refrigerant using a rotor with movable vanes (blade-like parts) and is ideal for small to medium-sized cars. 
  1. Reciprocating compressor: This type of compressor pressurizes the refrigerant using pistons and is usually used in older heavy-duty vehicles.

3. How to Save Money on AC Compressor Replacement?
