Air Conditioning Recharge |
Sometimes referred to as AC Recharge, Air Conditioning Recharge, Recharge
It may be necessary to recharge the air conditioning system refrigerant if the system has lost its cooling efficiency. Before any AC system repairs are performed, the system must be free of moisture and contaminates and leaks should already be repaired.
To recharge the AC system, gauges are attached to the AC system to measure pressures in the system, and refrigerant is added as needed.
AC systems should be worked on only by competent, trained personnel.
About this Repair: AC Recharge
Recommendations
We recommend using leak detection dye when recharging the AC to detect any problems with the AC systems.
Why this happens
AC systems require recharging when they become weak and do not perform well, or start to make unusual noise.
AC systems should not require recharging more than every 3 years, and do not require recharging if they are functioning properly.
"Stop leak" compounds are not recommended, as they are temporary solutions and can damage AC components, resulting in an expensive repair.
