Running air-conditioning when the outside temperature is below what degree Fahrenheit may damage the unit?

The correct answer is: 65

Running an air-conditioning unit when the outside temperature is below 65 degrees Fahrenheit may potentially cause damage to the unit. This is primarily because air conditioners are designed to function efficiently in warmer conditions. When the temperature drops below this threshold, the system may struggle to process the refrigerant effectively, which can lead to issues like compressor failure or frozen evaporator coils. When the outdoor temperature is too low, there is insufficient heat to absorb through the evaporator coil, which can result in improper cycling of the compressor. This not only decreases the machine's efficiency but can also lead to increased wear and tear or even catastrophic failure due to the strain placed on the system components. Therefore, avoiding operation under these conditions is crucial to maintaining the unit's longevity and preventing costly repairs.
