Weak Air Conditioning?

[Eka]

For heat sometimes I have to put it on manual mode and force the air on the floor or my feet be cold.

I noticed this same issue in my Model Y. Cold feet in the winter unless I force air to the floor. Auto mode doesn't work for the Midwest.

I notice the CT takes about 2/3 the time to cool the interior on a very hot day as my MY does. It also helps to crack the windows. That way the hot air can vent more easily. Your AC system might be a bit short on coolant. Leaves and bugs may be blocking the condenser.

For sure not the best I have had. My issue with it is when you keep active while you’re out of the truck it never keeps the temperature indicated. For some reason it never utilizes the rear air when in this mode too. Haven’t found a way to pre condition it in the rear.

You're saying Keep mode is running climate control, but not at the correct setting?

FWIW, there isn't a separate system for the rear (unlike the X 6/7 seat which had an extra air AC evaporator). So any rear air flow reduces front cooling capacity.

Yes keep mode runs but it never gets or stays at the temperature indicated. If I put it at 65 it’s not even close to 65 when I return. It’s still comfortable but it’s never cold.

My 24 FS works great in 100+ weather. I have full ceramic tint even on the front too. I've rested in camp mode in 110F weather in the middle of the day on long trips without issue.

Use your phone app to enable the ac before entering and change the temp to your desired setting. I have the fan shortcut on my top row and the Tesla widget on my home screen. I also use cabin OT set to 85F but it does seem to stop working if the vehicle is left unused for 12?+ hours and I have to reenable it from the app.

Does anyone find the CT air conditioning very weak?

On low temp, max fan, recirculation, and can barely bring the temps down on just an 82F day. And I have full ceramic window tint too!

And the fan makes a lot of noise but doesn't push a lot of air.

My 2024 Beast's AC is perfect, I leave it at 70 degrees and on hot days keeps the inside at 70 in pet mode for hours, and in below 0 degree weather blows plenty of hot air,,,,, and I keep mine in auto all the time. Sounds like yours need service for sure.

I'll check the HEPA filter and if it's OK, maybe have to take it into service.

Your radiator is likely full of leaves and debris, you can take a flashlight, plug into your wall charger and start charging, this will open the fins in the front bumper, look WAYY up in there, likely a bunch of leaves, trash, etc.
Likely need an aftermarket fine mesh guard, its the same issue people have on MY, problem is with the CT it is a LOT harder to clean the radiator.

Clean it out, or have service do it.
Change the HEPA
Buy an aftermarket grill fine mesh cover
Blast cool air

OK I'll take a look at that when I check the HEPA. One thing I forgot to mention; I keep the rear climate vents on too because of the dogs. I know the rear pulls cooling from the front, but still it's the same space so it shouldn't have such problems cooling the interior. I mean my top skylight window is completely blocked by a Urander bed cap, and all my glass including windshield is ceramic tinted. Really no CT should cool better than mine does but it's the opposite.

Has anyone else noticed that any front fan speed above 7 does nothing? Can anyone test? steps 1 up to 7 do audible increase in fan noise and air movement speed, but setting 8,9,10 seem to be exactly as level 7. Maybe test with and without the rear climate on? Maybe I'm losing my mind.

ALSO, I noticed if my wife turns off her passenger side air vents, that MY driver air vent wind speed ALSO drops. It's like turning off one of two motors or something if she turns off her vent that also affects me. Maybe my system is possessed.

EDIT: Oh I just realize something (sorry I'm sick); I'm at 8,000 feet altitude or about 2,500 meters. I get about 20% more solar radiation and 25% less air density than someone near sea level. I wonder if that is negatively impacting cooling capacity AND increasing thermal input. Any other high altitude peeps have AC issues?

I only notice sub par AC performance when I have the back vents turned on as well. When its just the front I can freeze without issue. When the rear is on at the same time it does steal the thunder.....

Oh my; after only 4 months and 5K miles in Colorado (with off-roading)

I start climate before leaving the house. Usually I start it 10 minutes before leaving, and it inevitably reaches the target temp in 5 minutes lol.

The only time the A/C couldn't keep up was during Supercharging on a hot day, where it prioritized cooling the HV pack.

The Service Menu can display temperatures and pressures in real-time.

I second all the HEPA posts, blew out the dust from my filter and it started blowing twice as hard

I'm in Denver, and the A/C in the CT has always felt weak to me. The fan is loud, even on low and it's cool enough, but just barely. I ceramic tinted the sides and windshield thinking it was just the amount of glass, but it still feels weak to me. It's been this way since new and I thought that's just the way it is, but it looks like I should check the filter anyway.

Ok so I'm not the only one...

So being in dusty rural Colorado, I thought hey let's use a "severe service" interval. Usually that's changing everything twice as often. So the manual says to change the HEPA every year, so I thought I'd be good doing at the 6 month mark. HECK FREAKING NO.

After 4 months it's basically passing no air, so maybe have to change it every 2-3 months. That gets expensive fast. I just put in a new filter and set my phone schedule for me to blow out the HEPA the 1st of every month. We'll see how it goes.

Hey I got something right and I don’t even own a ct anymore lol
