Do I need to vacuum AC before recharge?
If you don’t vacuum out an AC system prior to refilling it with refrigerant you will not get maximum performance because there will be minor amounts of air (humidity/moisture) in there. It is important to vacuum an air-conditioning system to remove any air or moisture that may damage the system in the long run.
How does an evac and recharge service work?
An “evac and recharge” service consists of connecting your car’s AC system to a special machine, which vacuums all the old refrigerant and oil from the system, and then refills it to the proper level. After the service is complete, the mechanic will test the system’s operation and verify that the air conditioner is cooling to the …
Where does the refrigerant go after an AC recharge?
The refrigerant then moves through the A/C lines and into the condenser, where the refrigerant cools as heat is released outside of the passenger compartment, and the refrigerant returns to a liquid. For the system to work optimally, the system must have the proper amount of refrigerant and be free of contaminants.
How often do air conditioners need to be recharged?
There’s no service or maintenance schedule here – you don’t need to recharge your air conditioning system every year, or even every two years. The best indicator that you need to recharge the refrigerant is when the system begins to cool less than it used to, but before it stops cooling completely.
Can a Jiffy Lube evacuation and recharge be repaired?
Jiffy Lube® does not recommend servicing systems with detected leaks or damage. The Jiffy Lube® A/C evacuation and recharge is designed for periodic maintenance rather than A/C repair, but rest assured that Jiffy Lube® can recommend the next steps to be taken to get you’re A/C system up and running.

When do I need to recharge my air conditioner?
When an air conditioning system loses its ability to cool properly, it may be necessary to recharge the system with new refrigerant. Keep reading for a R-134a A/C pressure chart and steps on how to recharge the A/C system when the system is low on pressure or has been vacuumed out following a repair.
Which is better, evacuation or recharge on a MVAC?
Evacuation and recharge service allows technicians to add the precise amount of refrigerant recommended by the MVAC manufacturer. Some technicians believe that evacuation and recharge is better for MVACs because the refrigerant is cleaned before being recharged.
How can I tell how much refrigerant is in my MVAC?
There is no way for technicians to determine how much refrigerant is in your MVAC system when you arrive at the shop, so they must guess how much refrigerant to charge into the system. They may undercharge or overcharge the system—both of which impair system performance.
