If a large amount of lubricant is removed from a system during refrigerant recovery?
tis is normal for an expansion valve/receiver dryer type
Can Replacing the AC Compressor in a 1996 ETC be a DIY Job?
Unless you have the proper equipment, skill, and knowledge to recover the refrigerant and to pressurize the system and install the proper amount of lubricant & refrigerant then you should seek out a professional. It is illegal to release refrigerant into the atmosphere and you will be fined heavily if caught.
What do you do to reduce the amount of friction?
put a lubricant
Why is subcooling desirable?
It increases the efficiency of the system since the amount of heat being removed per pound of refrigerant circulated is greater. In other words, you pump less refrigerant through the system to maintain the refrigerated temperature you want. This reduces the amount of time that the compressor must run to maintain the temperature. The amount of capacity boost which you get with each degree of subcooling varies with the refrigerant being used. Subcooling is beneficial because it prevents the liquid refrigerant from changing to a gas before it gets to the evaporator. Pressure drops in the liquid piping and vertical risers can reduce the refrigerant pressure to the point where it will boil or "flash" in the liquid line. This change of phase causes the refrigerant to absorb heat before it reaches the evaporator. Inadequate subcooling prevents the expansion valve from properly metering liquid refrigerant into the evaporator, resulting in poor system performance.
How do you change freon in a 1999 2.2 liter Chevrolet Cavalier and do you use the R134A kit to do it?
99 model year already is fitted with R134a from the factory. you shouldn't have to change the refrigerant. if there is a leak, repair the leak, then evacuate the system using a refrigerant recovery tool. Add the correct amount of oil if needed, and recharge the system with 134a.
What is the disadvantage of a dial scale?
They are more difficult to use when charging refrigerant into a system and more calculations are necessary to determine the amount of refrigerant charged.

What is the maximum recovery amount in small claims court in Florida?
The maximum amount of damage recovery for a small claims suit is $5,000. The state establishes the laws regarding monetary recovery, therefore, the maximum amount would be the same in any Florida small claims court.
Do you need a license to repair r-134a compressor?
By law, to do such work, you must be ASE certified, and the shop you're working in must be EPA certified to perform work on AC systems, and possess the necessary equipment. The refrigerant must be evacuated from the system - this requires a machine which does the recovery (it also weighs the amount of refrigerant recovered, which lets you know if more needs to be added or not). When the compressor is removed, the AC system is opened up. This means that the receiver-drier (if it's a Thermal Expansion Valve system) or accumulator (if it's a Fixed Orifice Tube system) must also be replaced.
How do you add refrigerant to 2004 Chrysler pacifica?
Refrigerant System ChargeWARNING: REFER TO THE APPLICABLE WARNINGS AND CAUTIONS FOR THIS SYSTEM BEFORE PERFORMING THE FOLLOWING OPERATION.After all refrigerant system leaks have been repaired and the refrigerant system has been evacuated, a refrigerant charge can be injected into the system. For the proper amount of the refrigerant charge, refer to the Underhood HVAC Specification Tag. An R-134a refrigerant recovery/recycling/charging station that meets SAE Standard J2210 must be used to charge the refrigerant system with R-134a refrigerant. See the operating instructions supplied by the equipment manufacturer for proper care and use of this equipment.REFRIGERANT CHARGE CAPACITYNOTE: Always refer to the underhood HVAC Specification Tag for the latest fill specification for the vehicle being serviced.CHARGING PROCEDUREEvacuate the refrigerant system .A manifold gauge set and a R-134a refrigerant recovery/recycling/charging station that meets SAE Standard J2210 should still be connected to the refrigerant system.Measure the proper amount of refrigerant (1.88 lb) and heat it to 52°C (125°F) with the charging station. See the operating instructions supplied by the equipment manufacturer for proper use of this equipment.Open both the suction and discharge valves, then open the charge valve to allow the heated refrigerant to flow into the system.When the transfer of refrigerant has stopped, close both the suction and discharge valves.If all of the refrigerant charge did not transfer from the dispensing device, open all of the windows in the vehicle and set the heater-air conditioner controls so that the compressor is engaged and the blower motor is operating at its lowest speed setting. Run the engine at a steady high idle (about 1400 rpm ). If the compressor will not engage, test the compressor clutch control circuit and repair as required.Open the suction valve to allow the remaining refrigerant to transfer to the refrigerant system.WARNING: TAKE CARE NOT TO OPEN THE DISCHARGE (HIGH PRESSURE) VALVE AT THIS TIME.Close the suction valve and test the system performance.Disconnect the charging station and manifold gauge set from the refrigerant system service ports.Reinstall the caps onto the refrigerant system service ports.Run the HVAC Control Cooldown test to verify proper operation.
How do I bleed excess refrigerant from my car?
When Releasing excess refrigerant from a car you are basically left with three options. Release the air using a $1,200 recovery unit, take it to a Certified ASE technician and have them do it right to the car's specific recomendations. The last option I personally do not recomened to anyone which is releasing the refrigerant into the atmosphere. Buy a set of manifold gauges, find the correct amount of refrigerant the car requires and keep releasing until the correct measurment is acheived. All together the illegal way is about $1,165 cheaper unless someone reports you and the EPA slaps the individual with a $10,000 fine.
