Recharging a Coleman Mach Air Conditioner is not a task to be taken lightly. These units are designed as closed and sealed systems, and ideally, they should never require refrigerant recharging. However, in some cases, you might suspect that your unit has a low refrigerant charge. In this comprehensive guide, we’ll walk you through the process, the safety measures to take, and how to troubleshoot, should you encounter any issues along the way.
Recharging a Coleman Mach Air Conditioner involves purchasing the correct refrigerant and supplies, shutting off the power to the unit, and using an RV air conditioner recharge kit to install access valves. You then open your air conditioner, check the current refrigerant levels using a gauge, and add the refrigerant slowly, following the manufacturer’s guidelines. Once done, close the air conditioner, restore power, and test the unit. However, this task is recommended to be done by a professional due to safety concerns.

Some models also come with optional heating capabilities for cooler outings.
When Does Your Air Conditioner Need Recharging?
A Coleman Mach Air Conditioner should ideally never need recharging. However, there are some situations where recharging might be necessary. Common reasons include refrigerant leaks or cracked coolant lines. Signs that your unit might be low on refrigerant include a longer cooling time, reduced airflow, and warm air coming from the unit. If you notice any of these signs, it’s recommended to have the unit evaluated by a qualified service technician.
