SIGNS OF AC COMPRESSOR FAILURE
AC compressor. One of the most essential parts of your car air conditioning system. Without it, cooling gases (ie air) could not be produced at the switch of a button and then carried right onto your sweaty brow. Without the common A/C compressor, who knows where we’d be now, but for sure, we’d be hot. But how can you tell when you’re having A/C compressor issues, and when is it time to get professional A/C compressor repair? And how Does the Compressor Work?
AC COMPRESSOR FAILURE SYMPTOMS
Car compressors work by pressurizing A/C refrigerant and passing it through a high/low-pressure system into the Condenser. The Condenser phase changes the refrigerant gas to a liquid state, which can then be evaporated again. These different phase changes are passed through the system, exchanging hot and cool air to cool your car’s interior. To keep this system running, the compressor typically transfers power from the engine’s crankshaft via a compressor belt. This transfer of power/energy reduces fuel economy, however. By disabling the A/C system, the A/C compressor clutch releases and spins freely, reducing friction against the crankshaft and improving fuel economy.
If you’re looking for more complex technical information about how compressors work (all compressors, car, and otherwise), check out this general info page on Wikipedia.
COMMON SIGNS OF AC COMPRESSOR PROBLEMS
If you pay attention, it can be obvious when your compressor is broken, or something is wrong with the cooling system. Check for these common issues for signs that your AC compressor is broken (or might be):
- Cooling isn’t working at all or not working well
- Loud noises, especially when the cooling system is working harder
- Using the A/C trips your vehicle’s circuit breaker (likely due to overworking the A/C system)
- The compressor clutch sticks or does not move at all
- Moisture leaks into the engine compartment or possibly even into the cabin
Many jobs on A/C systems require specialized tools like refrigerant reclamation systems and extensive time and training. Still, compressor belt replacement is a fairly reasonable job if you need to do it (presuming you have the tools, of course). Due to there being so many different makes and models of cars and trucks, we can’t give you specific advice on A/C compressor drive belt replacement, but if you’re curious about how the process works in general.
