How often do you use your A/C
 
I'm curious to see how often other Z owners feel the need to use the a/c in their cars. This is my first summer driving my Z and I have yet to use the a/c once other than to verify that it is functioning properly. I was pleasantly surprised to find that with the thermostat set to the coldest position, and the fan at low to medium speed, the airflow is able to cool the interior of the car quite effectively without having to run the compressor. Temps in Northern VA were in the mid 90s this weekend and I was very comfortable without having to use the a/c in my Z. I cannot say the same for any other vehicle that I have ever owned or driven. I was wondering if anyone else has noticed this and could possibly shed some light on the reasons why.

Uh... Daily. Except for when the temp is below say 82*F and low humidity, which does't happen very often down here in this turd state.

Mark1010 06-18-2017 07:46 PM

If the AC is on it is probably because I bumped it on.

DeliriousClam 06-18-2017 07:50 PM

Pretty damn close to daily unless it's nice outside

Fuzzzy 06-18-2017 07:52 PM

I'm not sure that I've ever turned it off.

MarkGideon 06-18-2017 07:56 PM

Pretty much any time I drive it from early March to late December, I will probably have the AC on. We do have a few weeks in Jan/Feb where it is almost winter.

JTM88 06-18-2017 07:56 PM

It's almost always on, except like 2-3 days out of the year

enkei2k 06-18-2017 09:43 PM

Rarely... I prefer to drive windows down and hearing my FI exhaust :driving:

Unless I'm doing freeway speeds, then windows up and A/C or heat set to low @ 75 degrees.

Sway 06-18-2017 09:50 PM

90% of the time mine is on...

PaulNYz 06-18-2017 09:51 PM

I only use it on the highway when its 85+ and humid. Otherwise it's windows down and fan on with no a/c.

I'm not a big fan of the slight load on the engine when shifting through gears in city driving.

Too6Z 06-18-2017 09:54 PM

Same here, but even so I rarely find that I need it and it gets pretty hot and humid here in VA.

I never shut mine off, Ever.

I've been trying to get by with wound down windows, but Atlanta is getting warm. I've been playing with the auto-temp-auto setting seeing if I like it. So far it seems to do well.

I do love that even with the AC on, I can still get up and go for highway merging.

370zHawaii 06-18-2017 10:55 PM

Everyday. Temps are between 78 to mid 90s almost all year round. I did learn a long time ago that it is a good idea to run it every now and then even if you live in cold weather climates as I didn't use my ac for 3 years in my old Mitsu and it caused the compressor to fail as it was never primed for so long, so keep that in mind.

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.

MacCool 06-19-2017 12:22 AM

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.

crazy4oldcars 06-19-2017 05:47 AM

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.

danegrey 06-19-2017 06:41 AM

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

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.

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.

Korstix 06-19-2017 08:31 AM

Same here. Only in the rain do i engage the ol' AC. Or if my GF is whining about her hair blowing around ahah.

SG4247 06-19-2017 10:28 AM

I run my A/C 100% of the time, with the interior recirculate button selected.

This filters out the smelly exhaust from running test pipes, very very well.

Smell is almost not noticeable at all with this method.

OldGuyFla 06-19-2017 02:29 PM

I only turn mine on about once a month to make sure it is still working.

Juso 06-19-2017 02:49 PM

At all times unless its not humid and not above 80 degrees. Too hot down here in the Houston summer!

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.

LOL, I live in Tucson Az over 110 here all week. We hit 90 for the first time this year in February. So I use the AC year round here.

Magic Bus 06-19-2017 06:48 PM

On 90% of the time for me. Gotta say, it's a great A/C. My old 04 G35 coupe which I had for 8 years, A/C was as cold the day I sold it versus day 1. Never did anything to it except, change the in cabin filter on a few occasions.

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.

brileafe 06-19-2017 07:47 PM

My climate control is always set to 70 so it will either heat or cool depending on the situation

I use it when my privates get damp.

I hate the thought of performance (power) going down with the AC on. But with the SoCal weather soring up to 100 recently, it's currently on.

Out of the year, I'd say the AC is on maybe 25% of the time.

MCDX 06-20-2017 12:51 AM

I am a window-down guy. Not a friend of dried air.
Normally only use A/C at speeds above 60mph or below 5mph. ;)
I don't think I can feel much of a power-loss in the Z. Never in a way as the EcoBoost Focus.

I have to try to fan-only method though!

Coupe 06-20-2017 03:02 PM

I rarely turn mine on,unless wife riding,plus just in case I get a 3 honk out of nowhere,I need full powaaaa....

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.

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.

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

jchammond 06-25-2017 08:07 AM

Everyday; windows up & A/C on recirculating.
