A vehicle's A/C system consists of a number of components, including the A/C compressor. The A/C does not cool without a working compressor, and the compressor does not function properly without a working A/C compressor clutch. In order to properly diagnose and fix problems associated with an A/C compressor clutch, consumers should develop a basic understanding of how the system works. Otherwise, they could spend time and money purchasing the wrong parts when they could have conducted some simple A/C compressor clutch diagnostics. The A/C compressor is essentially the working core of a vehicle's A/C system. When consumers turn on their A/C units, the A/C compressor starts to compress refrigerant in the system. This compression creates high pressure and raises the temperature of the refrigerant before it enters the A/C condenser. The A/C compressor clutch is in charge of alerting the compressor to start this compression. In other words, the compressor clutch is responsible for communicating to the A/C compressor when to start and stop operating.

The A/C compressor clutch actually has multiple components. Once the A/C system activates, the compressor clutch pulley starts to rotate the compressor clutch hub, which is a round metal piece located at the front of the clutch. The compressor's belt rides along the pulley. The compressor clutch hub attaches to the compressor shaft, which starts to rotate, creating both suction and discharge. The compressor's belt then forces the compressor clutch pulley to rotate, and that causes the compressor clutch coil to pull the hub against the pulley. The compressor clutch coil is tightly wound copper wire found below the pulley that acts as an electromagnet. These combined actions allow the A/C compressor clutch to engage the compressor and turn on the A/C. A lot of common A/C problems originate with the A/C compressor and the compressor clutch. However, before jumping to any conclusions, consumers should attempt to rule out any issues that could merely require simple fixes. If the A/C blows only moderately cool air when the temperature setting is at the coldest, owners can check a couple of things.

First, they need to ensure the cooling fans on the A/C radiator and A/C condenser work properly. They also need to look for debris that might be blocking the A/C condenser and keeping cold air from passing over it. 5 ton ac unit replacement costFinally, consumers should check the cabin air filter to ensure it is free of debris and contaminants.electric furnace and ac units Although a completely non-working A/C system could certainly indicate a serious problem, sometimes another culprit exists. air conditioner and heater canadaConsumers should examine A/C systems to determine that no breakers or fuses have tripped or blown because those issues prevent power from running through the A/C system. A/C compressor clutch problems regularly occur when routine maintenance does not take place on the vehicle's A/C system.

As a result, the A/C compressor clutch is often to blame for common A/C problems. Suction pressure is too high Discharge pressure is too low Compressor delivers inconsistent pressure to the refrigerant Addition of a shim to close air gaps between the hub and pulley Replace A/C compressor clutch If A/C compressor has voltage, probably defective compressor clutch Replace A/C compressor clutch A/C compressor clutch coil receiving inadequate voltage Overheating of internal winding Slippage of hub against the pulley A/C compressor clutch may have a defective pulley bearing With regards to most of these issues, the best solution is often to replace the A/C compressor clutch. However, qualified technicians are sometimes able to replace or fix individual components within the A/C compressor clutch. eBay has a wide selection of A/C compressor clutches and its components for purchase from a variety of reputable sellers, including clutches and related parts made by top brands like AC Delco, Motorcraft, and Four Seasons.

Search for the exact A/C compressor clutch part you need and then narrow down your search results by price, condition, or even the location of the seller. Before making a purchase, be sure to check out eBay's deals on car and truck parts to see if you can find what you need at the lowest possible price. Why Is My Air Conditioner’s Refrigerant Line Covered in Ice? Your outside air conditioning refrigerant line is covered in ice—which seems crazy in Arizona heat. Chances are, the indoor unit’s evaporator coil is frozen solid and cold liquid refrigerant is flowing to the outside unit through the refrigerant line (which is why it’s covered in ice). This is an evaporator coil. DO THIS RIGHT NOW: Turn off your AC and turn the fan setting to “On.” This will unfreeze the evaporator coil and prevent any damage to the compressor (a very expensive part you don’t want to replace). Now, let’s delve into what can cause an evaporator coil to freeze up and what you can do to ensure this never happens again.

What causes the evaporator coil to freeze up An evaporator coil, a group of copper tubes, freezes when the refrigerant flowing through the tubes gets too cold, causing the moisture in the surrounding air to freeze. So what causes the refrigerant to get too cold? Usually, it’s one of two things: Low airflow over the evaporator coil Low amounts of refrigerant What can cause these two problems? Let’s divide the possible causes into things you can solve right away and things you’ll need a technician to solve. Problems you can fix Clogged/dirty air filter—A dirty filter reduces airflow over the evaporator coil, causing it to freeze. Check the filter at least once a month. Closed supply vents—Don’t close supply vents (the vents that blow air out)—even in unused rooms. Closing vents reduces airflow over the evaporator coil. Blocked return vents—Ensure that furniture or curtains aren’t blocking the return vents (the grates where air gets sucked in).
