Aug 20, · How to recharge AC in a car. Want cold air in your car this summer? I show you a quick and cheap way to get cold air if you have a slow leak in your AC syste.
Recharging your AC means adding more refrigerant to your AC system to allow the air to start blowing cold again. Important to know: recharging your AC is a temporary fix to a likely bigger problem. If your system is indeed missing refrigerant, your air conditioning system has a leak and needs to be inspected and repaired with a certified mechanic.
Refrigerant does not evaporate in an airtight system, so air must be leaking in. Though an ac recharge can be completed at home, it is still considered a more professional repair, as it contains work with hazardous liquid and is best left for a certified mechanic. Because of the sensitivity of this procedure, we will explain how to use the AC recharge kits.
Tip : Always wear safety glasses when performing work under the hood. It is especially important to be careful to not get any refrigerant on your skin as it freezes quickly and is very painful. Step 2: Determine if AC compressor is engaging.
An AC compressor is a device driven by the accessory belt that converts the refrigerant from liquid to gas. The compressor has a clutch at the end of it that should be spinning with the accessory belt when the AC is on high. Look for these pulleys moving. If the clutch on the compressor is indeed engaging, then it is likely that the system is low on refrigerant, especially if the air is still blowing slightly cold.
You will still want to move ahead with testing the pressure before adding refrigerant. If the clutch is not engaging the compressor, then the AC system is either very low on refrigerant, there is an electrical problem, or the compressor itself has failed.
Adding more refrigerant after pressure testing will allow you to know which of these the cause is. Step 3: Test the pressure. To test the pressure, turn the vehicle off and locate the low side pressure port. The low side pressure service port is generally located on the passenger side of the engine bay.
Step 4: Attach the recharge hose from the kit. To attach the recharge hose, place the quick-connect fitting — found on the end of the recharge hose — over the port and push down firmly until you hear it click into place.
Step 5: Restart the vehicle and monitor the gauge. Restart the vehicle and make sure the air conditioner is on the highest settings. Begin to monitor the gauge by watching for the AC compressor to engage the clutch. Once the compressor is engaged, if the low side pressure is under 40 psi, it is verified that the AC system is undercharged.
You want the reading to be as close to 40 psi as possible. Step 6: Thread the refrigerant can onto the recharge hose. Threading the can onto the hose allows you to slowly top off the AC system with liquid refrigerant. Once the can is installed, hold the can upright and squeeze the trigger for 5 to 10 seconds to add the refrigerant to the system. After you release the trigger, check the pressure gauge to be sure you are not overcharging the system.
Step 7: Return to the inside of the car and check the temperature. A fully charged system will blow air as cold as 28 degrees. This can vary slightly depending on ambient temperature as well as whether the vehicle has been stationary. You have successfully recharged your AC! Your AC should be running colder now and your drive should be much nicer. The most popular service booked by readers of this article is Car AC Repair.
