How often do you use your A/C

Austinclr · 06-18-2017, 11:44 PM

If the A/C isn't on the car isn't on because Texas is hell on earth for a black car with black leather.

I set my interior temp somewhere between 72 and 74 and let the car decide if AC is necessary. I don't pay attention to whether it's on or not and can't think of a reason why I would.

this temp, 100%

I never turned mine off (meaning heat on cold winter). I however filled up the tank and want to experience if I will save on mpg. I'm a quarter tank and my car still reads 18 mpg. I just concluded it didn't make a difference for me so starting tomorrow I'm back to a/c.

Hell, color don't matter. Even the red is bad.

I keep Auto temp, auto fan and recirculate on year-round. Mitzee gives me what I need that way. 95% of the year, it's A/C. There's usually a couple of weeks in spring and fall that I run with the windows down.
Of course, the last couple of weeks, heat index has been around 110.

usually A/C on all the time and driving with the windows open, most of the year...

I was wondering if anyone else has noticed this and could possibly shed some light on the reasons why.

In mine, if I turn the thermostat to the coldest setting, the air flow automatically switches to recirculate and the A/C kicks on. However, the light doesn't come on indicating the A/C is on. I have to hit the A/C button so the light comes on then once again to get the A/C to kick off. If it's 90's outside then the air being pulled into the car will be in the 90's without some sort of cooling device. My guess is your A/C is actually running.

That is a possibility but the air coming from the vents doesn't seem cold enough for the a/c to be running on the coldest setting. It also seems strange that the light would not come on automatically. Perhaps I am wrong, though. I'll do some further investigation when I get a chance and let you know what I find.

It may not be as cold as deliberately turning on the A/C, it is however much cooler than running without AC. With it being mid 90s out the air coming from the vents is going to be mid 90s also unless you run the AC. The AC may not automatically kick on if the thermostat is set to the coldest setting when the car starts, it does if I turn it to the coldest setting from a higher setting afterwards though. You can completely cut off the AC by turning it on then back off.

OldGrayDog · 06-19-2017, 07:23 PM

Only if very hot and raining, so once in last 6 months. Windows, now they are open 90pct of the time.

I did a bit of experimenting and it turns out that you are 100 percent correct. You can definitely notice the difference in air temp if you cycle the a/c off in the manner mentioned. Well I just learned something new about my Z, guess I'll be riding windows down more often. It's still strikes me as odd that they design the system to kick on automatically without the light coming on but I guess they have their reasons.

Yeah and given it has two auto options on the dials. It doesn't make sense.

JARblue · 06-19-2017, 08:02 AM

Unless I have a passenger or its raining, I always have the windows down and AC off. Air blows through the vents while the car is moving, so I set the temp set to 60F in hot weather and 90F in cold weather. Even when I do have the AC on, the minimum fan speed is usually comfortable enough.
