How Do You Recharge a Semi Truck Air Conditioner?

Recharging a semi truck air conditioner is a relatively straightforward process that most truck owners are capable of doing. All that is needed to recharge the air conditioner is the correct type of refrigerant, a set of gauges, and a few tools.

With these tools, it is possible to accurately add the correct amount of refrigerant to the system without damaging it.

The first step in recharging your semi truck air conditioner is to locate and identify the low-side service port. This will be located on the line going from the compressor to the evaporator core. Once you have identified it, you can attach your service gauges and turn on your truck’s engine.

Next, you will need to start adding refrigerant slowly until both of your gauges reach their optimal readings. This will let you know that you have added enough refrigerant for your system to work correctly. It’s important that you do not overcharge or undercharge your system as this could lead to serious damage.

If after adding refrigerant, both of your gauges do not reach their optimal readings, then there may be an issue with one or more components within the air conditioning system. If this happens then it’s best to take your vehicle into a professional mechanic who can diagnose and repair any underlying problems.

Conclusion:

Recharging a semi truck air conditioner is something that most DIYers are capable of doing with relative ease. All that is needed is the correct type of refrigerant, some service gauges, and a few basic tools. With these items in hand, it’s possible to safely add enough refrigerant for your system to work correctly without causing any damage.
