How to Recharge Your A-C – Recharging Your A-C

Before you start recharging your vehicles air conditioner system, you want to check to see which refrigerant your car uses. Some automobiles use the newer recharge genshin impact. Other vehicles may still use the R12 refrigerant. If you plan on recharging you air conditioner yourself, you should always check the owner’s manual for your vehicle to see which refrigerant your car uses. You can also check your repair manual for this information as well.

If your vehicle was manufactured in the late 1990’s then there is a good chance your vehicle takes the R134 refrigerant. If your vehicle happens to use the older refrigerant, the R12, then you should visit your auto repair shop and have it converted to the newer refrigerant. You’ll be glad you did.

These kits usually contain a can of R134 and a pressure gauge – all in one. They do a good job with this particular do it yourself procedure. Even if you have limited or no experience with maintaining an air conditioning system, these all in one kits are simple and easy to understand. Some kits have a clearly visible pressure gauge right on the cap, but any all in one type kit will do.

In order to recharge the air conditioner’s system, you’ll need a pressurized refrigerant, or Freon, and a pressure gauge to observe how much Freon in the system. You can spend quite a bit on air conditioning recharging tools. Most of them are purchased by auto repair professionals. If you happen to have several automobiles, then it might make sense; it could really be worth the investment. However, if you only own a car or two, you might do better with an all-in-one kit.

Unpack your all in one kit. Locate the can of can of refrigerant, a rubber hose and the pressure gauge. Just follow the instructions enclosed in your all in one recharge kit package and assemble the pressure gauge. Usually, the flexible hose enclosed will already be attached to the gauge. Before screwing the gauge to your can of R 134 refrigerant, make sure you turn the gauge counter-clockwise gradually until it stops. You’ll find a pin in the assembly that you will use to pierce through the can of refrigerant once everything has been put together tightly.

When you’re ready, control the pin by turning your gauge clockwise until the pin pierces through the can. Remember you don’t want to pierce the can until you’re ready, so make the pin is all the way out before the kit is completely assembled. Making sure the pin is complete out, go ahead and assemble the pressure gauge and the rest of the kit. Screw that flexible rubber hose to the pressure gauge tightly. Don’t tighten the whole thing to the top of the can just yet. We will need to check reading first.

Before taking an accurate reading, you will need to calibrate the gauge. On the face of the gauge, you’ll find indications of different temperatures. Simply turn the calibration dial to match the outside temperature. If it happens to be a nice day, say 70 degrees outside, make sure you calibrate the temperature on the gauge to reflect the same.

Your air conditioning system has a low pressure and a high-pressure side. You want to recharge your air conditioner system through the low-pressure port side. Stop and consult your owner’s manual just in case. Your automobile will also have a cap over the high and low-pressure ports. One cap should be labeled “H” for the high-pressure port and the other will be labeled “L” for the low-pressure port. The ports are different sizes so there is no way you attach the pressure gauge or hose to the wrong port. It’s a type of safety measure but it’s always a good idea to check anyway.
