I live in Southern New England where it gets fairly cold in the winter, down in the single digits.
I noticed on my 97 Maxima, the air conditioner compressor runs when ever the car is set to defrost.
Is this normal?? Will this shorten the life of the unit running it in really cold weather???
Should I consider putting in a toggle switch to disable the compressor in the winter???
There are probably two schools of thought:
1) It destructive, the cold is bad for the seals with the oil being thick from the cold, seals fragile, etc.2) It's good for the compressor, because it keeps the compressor lubricated from time to time.
Air Conditioner professionals what would you do?
