Why do you charge an air conditioner or heat pump with refrigerant using the low side of the system?

the main reason is because the low side of the circuit is in a suction pulling from service port toward compressor when calling for cooling

Can you mix R401a and R409a?
No. You absolutely cannot mix any refrigerants. You should completely recover all the old refrigerant and charge the system, with the new refrigerant, using the superheat method.
How do you know when you need freon?
The only way to know if Freon (refrigerant) is needed in an air conditioner is to use tools and gauges to measure the performance of the system. The amount of refrigerant needed is based on the design of the entire system including the size of the unit, length and size of the refrigerant lines, temperatures, and type of refrigerant. Refrigerant is not consumed. If refrigerant is needed then the system was either not charged correctly when installed or there is a leak. There could be many reasons a system is not cooling. The correct answer to the question is: A skilled service technician will determined that the system was low on refrigerant by using pressure gauges, thermometers and other tools. There not function a home owner can perform to see if refrigerant is needed.
Will using an air conditioner in the winter break it?
not necessarily, but you will slugg the refrigerant back into compressor causing it to ware before its time
What is unlikely to affect refrigerant charge accuracy Ac compressor failure to calibrate the scale not accounting for refrigerant hoses using pressure reading to determine corr?
Ac compressor
How does one charge the air conditioner on a 1993 Jeep Grand Cherokee Limited?
First you need to find out if the system is a 134a system or not. It is then it recharged through the low port using one of those recharge kits from Walmart or Autozone or wherever. The port only fits on one side. If it is not a 134a system then you will have to have the expensive older freon put in or get a retrofit kit. The later is cheaper. Then refill with 134a. If system has been opened up then the system will have to be hooked to a vacuum pump and then filled with the proper amount of refrigerant and oil. Hope this helps.
When using R-134a refrigerant with UV dye as a liquid charge Can you use the same hose and adapter as with regular recharge?
the same hoses can be used. The dye only tints the Freon but does not hurt the hoses or the system.
What does the air conditioner refill port look like on a 2001 ford focus?
Schrader valves for R134a systems look the same in all vehicles using that refrigerant. It's a quick connect system... go to any auto parts store, and they can show you one.
How do you recharge the AC system on a Lincoln navigator?
Using r134 refrigerant. Look for the silver 5/8 line. Use a a/c charge kit attached to the low pressure side. I normally start the vehicle. But this is not the recommended method. Open valve on the charge kit and your done. You should see a professional to recharge. There is also an oil in the ac system that local store bought kits don't supply. Plus why did the refrigerant leak out in first place
How do you purge gas lines on a new samsung split system air con?
you need some specialized equipment this process generally refers to pumping pressurized nitrogen gas through the components (the tubing running to and from the indoor unit). The nitrogen gas carries out the moisture and any minor pieces of contaminate which will shorten system compressor life. Then you pressure test your connections based on the refrigerant you will be using. Then you pull a vacuum on the system to eliminate the nitrogen gas. then you release the refrigerant charge into the tubing and the indoor component (the entire refrigerant charge is shipped in the outdoor unit and is sealed in place until you unseal it with an allen wrench).
You added freon to your 2001 Sebring LXi and now it makes this humming noise The air works but you dont know what that noise is?
Did you add an oil charge to the system when you recharged it and did you recharge the system using refrigeration gauges. The system may be low on refrigerant oil or you could have overcharged the system causing the compressor to have to work too hard.
Can you have too much freon in your car?
Yes you can have too much refrigerant in your A/C system and it will damage the system. The only way to know how much is in the system is to measure it by using a gauge.
How do you use the gadget to put the freon in the car?
If you don't know your way around a refrigerant system get a mechanic to charge it for you. The pressures and temperatures in an operating HVAC system aren't trivial and should not be worked on by inexperienced personnel. You can check out the website linked below. It isn't difficult to put the refrigerant into your AC system. You will be charging on the low side and depending on which gauge you are using on how to use it. Check out the website and they also have a Tech Support Line to give you detailed answers.
