Can an AC car recharge kit be used for commercial vehicles?

A leaking car air conditioner may seem like an easy fix at home, but it can lead to bigger problems. DIY manual recharge kits promise to restore ice-cold air in just a few steps, but it’s important to know how the process really works, before you try it at home.

The reason your car’s AC needs to be recharged is that the refrigerant gas that makes it work will leak out over time, reducing the pressure in the system. That’s why it’s important to use a kit that uses the right type of refrigerant for your vehicle, which is typically either R134a or R1234YF.

The easiest way to find out what kind of refrigerant your vehicle’s AC uses is to consult its owner’s manual. If you don’t have the manual, the AC recharge kit’s paperwork or an online vehicle service database can help you determine what kind of refrigerant your car’s AC system needs to operate properly.

Before you can start recharging the AC, it’s important to locate the refrigerant ports under the hood. These are the barb-like fittings sticking out of the metal AC lines. You want to locate the low-pressure port, which is on the thicker pipe and marked with a blue or black cap (R134a) or an orange one (R1234YF). The high-pressure port is on the thinner tube and marked with a red or green cap. Once you’ve found the ports, remove the caps and set them aside somewhere safe. You’ll need them later for the test phase of the recharging process.

When recharging the AC, it’s crucial to wear gloves and eye protection. The flammable refrigerant can cause frostbite if it comes in contact with your skin or eyes, so be sure to wear appropriate safety gear. You’ll also be running your engine while doing the recharging, which means there will be spinning belts and pulleys and hot parts that can burn to the touch. It’s also a good idea to tie back long hair and wear pants, a shirt with sleeves, and close-toed shoes while working under the hood.

Recharge the AC by connecting the recharge kit hose to the low-pressure port. Follow the instructions in your recharge kit to determine how much refrigerant to add to your vehicle’s system, based on ambient temperature and a recommended pressure range. Keep recharging the system until the pressure gauge reads the optimal PSI for your climate. Be sure to shake the can of refrigerant slightly every 3 to 4 seconds to ensure all the contents are mixed evenly. Avoid recharging the system if it’s already filled to the max PSI limit, as this can damage the compressor and other components of the AC system. For the best results, consider having a certified mechanic or auto technician perform your a/c recharge. They’ll first clean out the old refrigerant, moisture, and contaminants from the AC system and then refill it with the proper amount of refrigerant.
