The recommendation to let an air conditioner sit for 24 hours after installation or movement is often advised to allow the refrigerant system to stabilize before operating the unit. This period is commonly referred to as the "settling" or "resting" period. Here's why it is suggested:
Refrigerant Flow: Air conditioners contain a refrigerant, a substance responsible for absorbing and releasing heat to cool the air. During installation or movement, the air conditioner may have been tilted or jostled, causing the refrigerant to shift from its intended position. Allowing the unit to sit undisturbed for 24 hours ensures that the refrigerant settles back into its proper place, preventing potential damage to the system and ensuring optimal performance.
Oil Return: Within the air conditioning system, there is typically oil that lubricates the compressor, which is responsible for circulating the refrigerant. When the unit is moved or installed, the oil can flow away from the compressor. Allowing the air conditioner to sit for 24 hours allows the oil to return to its intended location, ensuring proper lubrication and preventing potential compressor damage during startup.
System Pressure: During transportation or installation, the air conditioning system can experience changes in pressure. Allowing the unit to sit for 24 hours allows the internal pressure to stabilize. This is particularly important before starting the system to avoid potential damage and ensure proper functioning.
While the 24-hour resting period is often recommended, it's essential to consult the manufacturer's guidelines or the installation manual specific to your air conditioner. Different models may have different requirements or considerations, so following the manufacturer's instructions will ensure the best practices for your particular unit.
