Do you add Freon to the high side?
The freon is added on the LOW PRESSURE SIDE ONLY. The hose tool you bought is made so you can only hook to the low side as the high side and low side fittings are different sizes and shapes for SAFETY’S SAKE.
What is 12a refrigerant?
HC- 12a , also called ES- 12a , OZ- 12a , and Hydrocarbon Blend B, is a “drop-in” replacement refrigerant for Freon -12 and to a lesser extent, R-134a. HC- 12a provides better cooling than an R-12 system retrofitted to R-134a, with much greater energy efficiency as well.
Can I use automotive r134a in a refrigerator?
No, R 134A is a refrigerant for a car AC and cannot be used in a refrigerator due to pressure difference. Refrigerators generally use R22, R32 or R410A.
Can I add r134a to a r12 system?
No. Federal law prohibits topping off an R12 system with a different refrigerant. Or you can convert the system using one of our R134a retrofit kits, that will allow you to now add 134a refrigerant to your automotive air conditioning system .
Can I put r134a in a r12 system?
R134a systems operate at higher discharge-side pressures than R12 , which can cause compressor seals to leak. Bottom line, R134a simply doesn’t cool as well as R12 . The advantage of ester oil is that it works with both R12 as well as R134a , so you can fill the system with it and then use either refrigerant.
Can you mix r12 and 134a refrigerant?
You cannot mix R-12 with R- 134a , they are not compatible (and neither are the compressor oils used with them).
Does a mini fridge Need freon?
Just like full-size refrigerators and freezers, mini – fridges contain insulation and refrigerant that should only be handled by a professional.
Do you charge AC on high or low side?
After replacing a failed component the system is “flat” you are now ready to vacuum the system down and recharge it. The high side port should be on the line between the condenser and the expansion valve or orifice tube while the low side port will be on the return line between the evaporator (firewall) and compressor.
How do I know if my freezer needs freon?
Locate the refrigerator’s condenser and place your hand next to it to sense heat. If the condenser feels cold and the refrigerator has been running, there may be a lack or absence of Freon .
Does AutoZone add freon?

How many cans of Freon does a car take?
How much refrigerant do I add?
The General Rule of Thumb When estimating the amount of refrigerant in a residential A/C unit, the general rule that is used is in the 2-4 pounds per ton of cooling. Say, for instance, recharging a 3-ton A/C with a 35-foot line set from empty level will need an approximately 6-12 pounds of refrigerants .
