Why Does My AC Compressor Break?

A serpentine belt does more than power the air conditioning system on modern cars; it also powers alternators and water pump. When this belt malfunctions, its impact could lead to engine overheating.

If you hear chattering, whining or chirping noises near the engine, this could indicate that it needs service for several reasons.

Slackening Belt

A serpentine belt may last for thousands of miles before starting to loosen and cause your compressor to stop functioning properly.

Misaligning of pulleys is often responsible for this situation. Aligning pulleys correctly reduces friction and allows accessories to rotate at normal speeds – helping prevent sheave damage and heat build-up.

To check alignment, loosen but don’t remove the motor bolts and move the motor closer to the pump. Place a straight edge across two points on your belt at two locations on it before adjusting the pulley until its path follows that straight edge exactly. Correct tension can help protect sheaves and bearings against damage as well.

An untight belt may need replacing. But with a serpentine belt tensioner in place, automatically adjusting tension is no longer a worry and saves money over time.

Seizing Compressor

An AC compressor that won’t start is likely mechanically stuck; its main function is to initiate compression-induced chain reactions within its condenser, receiver/drier and evaporator to keep your vehicle cool.

Your air conditioning draws power from the serpentine belt when activated. As your engine churns away, so does its compressor, cycling on and off to reduce wear and improve fuel economy.

When the AC switch is turned on, a clutch connecting to the compressor pulley and belt engages. While its center remains stationary when turned off, when activated by an electrical signal from the compressor cycling switch it starts spinning around its own axis.

As your serpentine belt also connects the alternator, power steering pump, and water pump, its failure can have serious repercussions for your car’s engine. A seized compressor could overheat and stop working while driving, leaving no cooling for passengers or prompting the check engine light to illuminate.

Low Refrigerant Levels

Your air conditioner requires a certain level of refrigerant, usually known as Freon, in order to operate effectively. This chemical cycle between liquid and gaseous states as it travels between compressor and evaporator fins; any leakage or contamination could reduce system performance and have detrimental results on system efficiency.

If your compressor makes strange clunking or rattling noises, this could indicate low refrigerant levels in your system and needs immediate attention.

Modern cars rely heavily on serpentine belts to power more than just their air conditioning; they may also connect to alternators and power steering pumps. When the belt fails, additional strain will be put on these components which could cause them to wear out and lead to expensive repairs down the line. If you suspect your serpentine belt may have gone bad, seek advice from an auto repair expert immediately if that is suspected.

Stationary Compressor

The stationary compressor is a heavy-duty unit designed to deliver large volumes of air, making it perfect for powering pneumatic tools. Since this type of air compressor doesn’t need to be moved from place to place, its efficiency far outstrips that of portable alternatives. However, you should keep in mind that three-phase electricity may not be readily available where you live or do business.

AC compressors are essential components of your car’s cooling system, pumping refrigerant through its lines to absorb heat and expel cold air. A well-maintained compressor may last 15 years with proper care but eventually wear down; any damage due to internal or external factors could be detrimental to other electrical components in your vehicle, so always pay attention to symptoms of an impaired compressor so it can be addressed as quickly as possible.
