Do you charge AC on high or low side?
Every auto air conditioning system has two service ports: one on the high pressure and one on the low pressure side. When recharging with AC Avalanche refrigerant, for safety, you will charge through the low side service port. Never charge through the high side port.
How often do you recharge freon?
Never. You shouldn’t have to “add” refrigerant to a central air conditioner because it doesn’t “use up” refrigerant. The only reason you would ever need to recharge (that is, add refrigerant to) your A/C is if you have a leak; once the leak is fixed, the problem should be solved.
How do you fill r134a refrigerant?
Service port usually located on the larger line that goes to the compressor into the firewall. And remove the dust cap. You can tell that the system has no refrigerant.
How do you use avalanche 134a refrigerant 10oz?
Directions
- Remove the clear plastic cap.
- Locate the vehicle’s low side service port.
- Start engine and turn in conditioner to maximum cool and maximum air flow.
- Shake can well.
- Connect the recharge hose to the low side service port by pulling the connector ring back as you push the fitting onto the service port.
Do you need to vacuum AC before recharge?
The air needs to be evacuated to remove not only the air (which makes a lousy refrigerant), but also the water vapor in the air. Yes, you need to add the proper amount of oil. But you need to drain the old oil first to ensure you don’t end up with too much.
What happens if you charge car AC on high side?
The damage from trying to charge on the high side would be to you – not the system. More than likely the pressure would back up into the can and explode it like a grenade. If you don’t know what you’re doing, seriously get someone to help out. You ALWAYS want to connect to the low side.
How do I know if my AC is low on Freon?
Five Signs your AC is Low on Freon
- It takes much longer than it should to cool off your home.
- Your utility bills are higher than usual.
- The air coming out of your vents isn’t cold.
- Ice has started to build up on your refrigerant line.
- You hear loud or unusual noises coming from your unit.
How do you know if your AC needs Freon?
How to Know If Your AC Needs Freon
- The AC runs constantly without cooling the house.
- The air from your vents isn’t cold.
- You have abnormally high energy bills (because the system runs continuously.
- There’s ice on the refrigerant lines.
- Bubbling or hissing sounds happen when the AC isn’t running.
Is R134a the same as 134A?
Yes, it’s the same refrigerant. The regular R-134A has a 1/4″ flare connector, and the Auto (Mobile Air Conditioning) cylinder has an SAE connector. If you look at the following links, you can see that they are both 1,1,1,2 tetrafluoroethane.
Does R134a need to be charged as liquid?
R134A……
Being a pure refrigerants, R134a, R12 and R22 can be charged either way. The blends like R401A, R409A, R410A and all in the 400 series of refrigerants must be charges as a liquid.
How do I put an avalanche refrigerant in my car?

What happens if I don’t vacuum my AC system?
KOG. What will happen if you don’t evacuate moisture is that the acids formed by high temperature reaction of refrigerant and moisture will destroy the condenser, the evaporator, the compressor and any control valves in the system as well as any aluminum lines. In other words, every part of the entire system.
How do I evacuate my car AC without a vacuum pump?
Here are some steps to show you just how to vacuum your AC without a pump.
- Depressing the Access Valve.
- Charging the Low-Pressure Side.
- Repeat Step One (Depress the High-Pressure Side Access Valve)
- Repeat the 2nd and 3rd Steps.
- Charge With Refrigerant.
How do I evacuate my car AC without a pump?
What is the correct AC pressure on a car?
The low-side should be near 30 PSI at 90 degrees Fahrenheit or less. Pressure that is too much lower or higher shows there is a problem. On a properly working system, high-side pressure will be about twice the ambient temperature, plus 50 PSI.
Is it OK to run AC without Freon?
Without any refrigerant at all, your air conditioning system would be incapable of cooling your home.
Can I add Freon to my AC unit myself?
It’s possible to add Freon to your air conditioner unit yourself, but you’ll need some general knowledge about ACs and a few specific tools to do it correctly. The process can be dangerous, so hire a qualified professional if you feel unsure about what to do.
What happens if Freon is low?
A low Freon charge can lead to compressor damage and overall inefficiencies of the air conditioning unit. This problem happens when the low refrigerant causes freezing on the evaporator coils. Eventually, the ice build-up leads to the insulation of the coils and slows the cooling process.
When was R134a banned?
HFC-134a will no longer be approved for use in new light-duty vehicles manufactured or sold in the United States as of model year 2021 as a result of EPA’s July 2015 final rule under SNAP (July 20, 2015, 80 FR 42870Exit Exit EPA website).
Can I use R134 instead of R134a?
Is R134A refrigerant liquid or gas?
1,1,1,2-Tetrafluoroethane – R-134a – is an inert gas used primarily as a high-temperature refrigerant for domestic refrigeration and automobile air conditioners.
Can you charge refrigerant through the high side?
For systems under a vacuum, once the desired vacuum level has been reached, the vacuum pump has been isolated from the system, and no leaks exist, always charge liquid refrigerant in the high side of the system until high- and low-side pressures equalize and liquid stops flowing.
