Home air conditioning systems typically use R-22 or R-410A refrigerant, while car air conditioning systems usually use R-134a refrigerant. These refrigerants have different properties and characteristics, so using the wrong one can cause problems.
Car recharge kits are also designed for the smaller, more compact air conditioning systems found in cars. Home air conditioning systems are much larger and may require a different type of refrigerant and a higher charge pressure. Using a car recharge kit on a home air conditioner could result in overcharging the system, which could cause damage to the compressor and other components.
It is important to consult with a qualified HVAC technician to properly recharge your home air conditioning system. They will have the knowledge and experience to safely and effectively recharge your system with the correct refrigerant and charge pressure.
