Sense on the lines of A/C I find no need to creat a new post.. I have noticed my A/C is running quite frequently when I have my controls set to defrost. I know this is normal but would it be recommended to unplug the compressor during colder weather we’re A/C is not actually required. To help offset some of the weather fuel mileage drops? No matter if controls are set to the hottest setting or not on defrost it cycles.
