What is an AC Recharge all about? For an AC system to work, it needs a gas or liquid substance called refrigerant ( R-12 Freon in older cars, R-134a in 1995 and newer cars). Over time, refrigerant can leak from the AC system through seals. If the AC does not have enough refrigerant, it will not blow cold air. Since the AC system is a sealed unit, the only way to tell if the car needs a recharge is if the AC is not blowing cold air through the vents. There are two types of refrigerant. These cannot be interchanged. For older cars, it should be filled with R12 Freon or converted to a newer system. For cars made after 1995, the AC should be filled with R134a. Install air conditioning manifold gauge set. Determine if the air conditioning system charge is low. Add the correct refrigerant to top off the air conditioning system. Install thermometer in vents to monitor vent temperatures. Check system for leaks. Check for proper operation of AC system.

It is common for refrigerant to leak. If the AC is not as cold as you expect, then it is probably a good time to have the mechanic look at it. Lack of proper cold air can be an indication of other problems with AC (fan not working, AC compressor not working, etc.).

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. Evacuate and recharge the AC system. 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?
