dmaxorpantax 10-17-2008, 06:27 PM is it bad for my air conditioning system,eg. pump, lines, seals to unhook it through winter so it does not kick on every time the defrost gets turned on?. so basically unhooking it for 7 months. is this going to cause leaks or pump failure by it not moving all winter??? the seals could dry out??? nmband13 10-17-2008, 06:38 PM if you unhook it your windows will fog up, the a/c is used to dehumidify the air in the winter so that your windows dont fog over, you can unhook it but I wouldn't. edit: if you do unhook it make sure you only take the one wire connection going to the a/c compressor. dmaxorpantax 10-17-2008, 07:22 PM how does it de-humidify it? brian1 10-17-2008, 07:42 PM When air passes over the evaporator coil it is cooler and condense water vapor in the air to water and drains away. Also it is recommended that the compressor run from time to time like it does in the winter to keep oil in the refrigerant recirculating to keep seals from drying out and causing leaks. Brian dmaxorpantax 10-17-2008, 08:36 PM i will hook it back up then thanks guys CAJUN86 10-18-2008, 12:35 PM I have unhooked mine the past 4 winters, with no ill-effects . A/C still works great during the summer, blew 42 degrees inside this summer when outside temp was 92 degrees. Fogging is not an issue 95 % of the time, only if you keep it on re-circulate for extended periods. I keep it on re-circulate till its warm enough inside or in stop and go traffic, saves on the exhaust smell. I live in Michigan and gets unhooked for 6 months every winter.

Brian Well said, alot of folks do not realize the system works together.... Roegs 10-18-2008, 07:36 PM I used to disconnect my AC during the winter years ago. The theory was that it would protect the compressor from running when it was too cold. AC systems are much better now, and much better protected. My advice is to use it as it was designed to be used. If nothing else, it's a safety issue by providing the best possible defrost during humid times. The small savings you get by disconnecting are not worth it IMHO. snopro 10-31-2009, 06:38 PM I used to disconnect my AC during the winter years ago.

I am unhooking mine for this winter as well - this will be the first time I have done this. I guess I will see how well it defrosts. I just hate the AC coming on in the middle of winter just to try to defrost the windows...

Ever see the water dripping from the truck in the summer on a hot humid day? Winter days can be just as humid. A 32 degree day with heavy wet snow fall....thats 100% humidity. You'll fog up quick!! It doesn't hurt a thing to run these systems. Its probably worse to not run it. | ||
