AC Button Help!!!

BMW_Fan01 · 02-25-2019, 12:55 AM

Okay so I have to this for long time but couldn't find the answer. Also I'm new here.
So I have a BMW F10 and my question is simple. Do I need to turn on the AC button when I'm using the heat? Recently I had radiator fan issue and someone told me that it happened coz I never turned on my ac button while using heat?? They said I need to keep the AC button on at all times. Is it true and why?

You don't 'need' the A/C switched on to run heat. If you want full climate control, including dehumidifying, you do need it switched on. Many users simply leave it on and let it do its job. Cabin can be more comfortable and set without having heating/cooling extremes.

There is concern that if you don't run the A/C, there can be issues with premature failure/leaks due to not being used regularly.

Latest HVAC systems are not so energy hungry, like older systems. Variable output compressors mean fuel penalties are not of any real concern, when demands are low.

Put your car on AUTO, find a temperature you like and let your car do the work to keep you comfortable. It'll turn the AC on when needed for you.

Ditto the above...I believe it is discussed in the owners manual. If you use the AUTO function...it will run the AC compressor if needed...as well as activate the condensation sensor as needed.

It will also reduce the need to constantly adjust the blower speed (except for very rare occasions). Why have to touch the HVAC buttons when you can basically set-it and forget-it for most of the year.

EDIT: yep...it's discussed in the owners manual.

Press AUTO, Select your temp, and let the car do the rest. BMW taught me this 18 years ago. I cannot go back to toggling setting any more
