    Can I Drive With Air Conditioner Issues

    If the air conditioning system has been emptied – either by way of a damaged component through accidental discharge, or by way of refrigerant recovery – the air conditioner will not operate. A low pressure switch ensures that the AC compressor will not operate if the refrigerant pressure gets too low, as it would if the system were empty. A vehicle without air conditioning can be an inconvenience. It does not present an immediate safety concern. The vehicle can be driven without it. However, the longer the air conditioning system is left empty of refrigerant, the higher the likelihood that moisture will enter the system and compromise the integrity of the components – especially the AC compressor – leading to premature failure.

    Disconnect The Recovery Machine

    How to recover R134a refrigerant from a car

    The final step of removing Freon from the car AC is disconnecting or unhitching the recovery machine from the service port.

    Remember you have to close the server hose valves before disconnecting the recovery machine. Otherwise, your car A/C compressor will get damaged, and when your A/C compressor gets damaged, the AC wont blow cold air when the cars idling or running. Thats why you should be careful when you disconnect the recovery machine.

    Some old model recovery machines that can only be used to drain R-12 type of Freon need to shut off valves on the hose. But in the case of an R-134a Freon, you get a quick detachment system to prevalent refrigerant loss.

    Hire A Certified Technician To Remove Your Freon

    If youve been instructed to have a technician dispose of Freon before you get rid of your refrigerator or air conditioner, its time to find the right person. Use these guidelines to make sure you hire a reputable and certified technician.

    Do Your Research

    Besides asking your local municipality for recommendations, you can also research HVAC technicians like you might for any home project: online and through word of mouth.

    If youre using the web as your primary form of research, check websites such as:

    These sites should provide a list of technicians in your area along with their BBB rating and reviews. You can also Google the companys or persons name and browse through any other reviews that pop up.

    As youre reading through reviews, watch out for any mentions of technicians who do not have the right credentials, certifications, insurance or bonding, have provided poor service or consistently receive negative feedback.

    Finally, if youre relying on the opinions and advice of people in your social circle, reach out to your friends, family, coworkers or other people you trust in person or online. For instance, you may want to consider posting something on social media or in a community group.

    Ask the Right Questions

    Once you have a list of potential technicians to work with, reach out and ask a few specific questions to screen them.

    First, ask if the technician or service company is Section 608 certified. If theyre not, move on to the next name on your list.

    Note: More Refrigerant Can Be Transferred From The System To The Recovery Tank If The Tank Is Empty And In A Vacuum

  • Bleed a small amount of refrigerant from each line through the center line and allow it to seep out at the cylinder connection. This purges any contaminants from the gauge manifold and the refrigeration hoses.
  • Set the recovery cylinder on the scale.
  • Zero the display on the refrigerant scale.
  • Start the system and open the valve arrangement between the liquid line and the cylinder. Liquid refrigerant starts to be pumped into the cylinder cylinder compressor the AC system.
  • Watch the high-pressure gauge and do not allow the system pressure to rise above the working pressure of the refrigerant cylinder.

  • Watch the suction pressure on you gauge manifold and do not allow it to fall below 0 psig. When it reaches 0 psig, you have removed all the refrigerant from the system that you can, using this method.
  • Remove the refrigerant cylinder. You may need to recover the remaining refrigerant using recovery equipment.
  • Recovery can be sped up by setting the recovery cylinder in a bucket of ice, thus reducing the pressure in the cylinder.
  • There you have it! Most HVAC Service Technicians have not had the proper training on using this method of refrigerant recovery.

In a new vehicle, it is only necessary to perform this service every two years after a complete cleaning of the system. Although this is true every summer, many motorists who notice that their cars air conditioning is not working properly, i.e. it does not cool or cool the passenger compartment as it should, look to garages that offer air conditioning recharges without the need for further inspection or testing.

    Recover Refrigerant & Pull a vacuum on your car AC

    Currently, there are digitalized machines which can remove the refrigerant, recycle it and make it reusable for your cars AC. If you are going to use the machine, then follow the below process.

    Step-1: Attach the service hose of the machine to the ac system service port of your car. You will need to attach it in the low-pressure service port of the car. Follow the hose that runs from the back of the compressor to the accumulator near the firewall. In the backside of the compressor, the low-pressure bigger two lines are the low-pressure line. The high-pressure port is in between the firewall and the condenser of the high-pressure line. The capacitor is situated in front of the radiator. The high-pressure line is usually thicker than the low-pressure line.

    Step-2: Now start the machine. It will begin removing the refrigerant from the ac system. If there is any refrigerant in the system in liquid form, then the device will reduce the drop of the system. It will make the refrigerant to turn into vapor and come out from the system. If the system becomes empty, the machine will automatically shut off and monitor the pressure inside the system. If it rises, the machine will restart again and start removing the remaining. It will wait 5 to 10 minutes, and if the system stays at the empty state, then it will complete the process.
