Hello.

I noticed that refrigerator compressors are leaps and bounds more expensive per watt than air conditioner compressors here, but, I am also curious, what is the difference?

Could it be that refrigerator compressors can operate safely at low freezing temperatures that typical air conditioner compressors cannot?

Also, does anyone know what the minimum temperature a 9,000 BTU standard A/C can safely operate at is?

Thank you for your time.
