What is the AC Compressor all about? An AC system has many components: compressor, condenser, receiver dryer, evaporator, and hoses. The compressor, the “heart” of the car’s air conditioning system works like a pump taking refrigerant, ( R-12 Freon in older cars, R-134a in 1995 and newer cars) and pressurizing it, passing it along to the evaporator. The AC compressor has several moving parts (including pistons and valves). These internal parts can fail, causing the AC compressor to stop working. It is common for the internal parts of the compressor to come apart and disperse metallic debris throughout the system. Consequently, it is a requirement to replace the orifice tube and the receiver dryer when replacing the compressor since some of the debris may have ended up there. For an AC compressor to work, it needs a clutch, bearing, and an electrical connector. The clutch is driven by a drive/serpentine belt, which engages the compressor when you switch on the AC. The clutch can burn or the bearing can fail.

If the bearing or clutch have failed, it is recommended that the compressor be replaced. Sometimes replacing the entire compressor with a remanufactured one can be cheaper than replacing an individual clutch or bearings. It is also common for the seals in the AC compressor to go bad. The compressor may start leaking refrigerant and/or the AC oil. If the seals no longer hold, you will need a new compressor, as the seals cannot be replaced. A compressor may also fail if there is sludge or debris in the air conditioning system. If there is sludge or debris, the hoses, evaporator, and condenser should be flushed to get rid of the contaminants. When it is not possible to flush the parts, you may need to replace those parts. This service comes with receiver dryer and orifice tube. It is very common for metals from the compressors to go throughout the system and get caught in different components. If the compressor is replaced without the dryer and the orifice tube, it will ruin the new compressor and it will not be covered by the warranty from parts manufacturers.

Check for pressure in the AC system. Check for power and ground at the compressor. If compressor is found to be faulty, remove all of the refrigerant. Remove the compressor, receiver drier, orifice tube, and/or expansion valve. Flush all foreign materials from the AC System. Install new compressor, receiver drier, and orifice tube. The most common reason for an AC compressor to fail is leaky seals and inadequate lubrication. It is good practice to turn the AC on periodically so that the seals don’t dry up and stay lubricated. If you notice a change in the temperature of the air through the AC vents (not as cold as it should be), get it inspected. What common symptoms indicate you may need to replace the AC Compressor?

We are one of the nation's leading inspection and evaluation companies in the industry and specialize in Pre-Purchase Inspections, Lease Return Inspections / End of Lease Inspections, Mechanical Failure Inspections and also provide Legal Inspections and Evaluations for attorneys involved in Lemon Law and Breach of Warranty cases. Important things to remember when planning to purchase a used vehicle without the opinion of a professional and the addition of an extended warranty:cost of new ac and heating unit ENGINE REPAIRS: There are hundreds of internal lubricated parts. wall mounted air conditioning unit installationThe average repair for an internal engine failure repair is over $2000.00 and up to $5000.00 if the engine needs replaced. split system air conditioners cost

There may be symptoms present that are not detectable by the average used car buyer. TRANSMISSION REPAIRS: There are internal lubricated parts, including seals gaskets and clutches that rely on each other. The average cost of repair for internal failure can be as much as $2000.00 and up to $4000.00 or more for the average vehicle. DRIVE AXLES and DIFFERENTIAL REPAIRS: Repairs to any of the vehicles drive axles or differentials can be very expensive, especially if they were not maintained. The average repair costs can range from $1000.00 to $2000.00 for an internal failure and more if the complete assembly needs to be replaced. FOUR WHEEL DRIVE - ALL WHEEL DRIVE REPAIRS: These are also very complexed systems that are very expensive to repair or replace costing $1000.00 to $2000.00. STEERING SYSTEM REPAIRS: There are one hundred or more individual parts (moving or stationary) - The average cost of repair is $500.00 to $1500.00. SUSPENSION SYSTEM REPAIRS: There are many individual parts depending on advanced systems - The average cost of repair is $500.00 to $1000.00 or more.

BRAKE REPAIRS: There are many individual wearable parts not including the Anti-Lock Brake System (ABS) - The average cost of repair is $350.00 to over $1000.00. COOLING SYSTEM REPAIRS: There are many components in the cooling system that are affected by normal wear and tear driving - The average cost of repair is over $400.00. Timing belt driven water pumps can cost over $900.00. SEALS and GASKETS REPAIRS: Cylinder head gaskets and intake manifold gaskets are common failures to many vehicles - The average cost of repair can range from $500.00 to over $1000.00. AIR CONDITIONER and HEATER REPAIRS: Many vehicles do not blow cold air. The seller states it just needs a tune-up charge of freon. This means the original charge must have leaked out somewhere over time. A professional inspector has many years of training and experience to detect where freon normally leaks from and may be able to tell with a visual inspection of the air conditioning components if evidence is present.
