Weak Air Conditioning?

[CallsignVega]

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.

There seems to be a software bug that leaves it in windshield mode sometimes when in auto. Did you try manual mode?

Ya I rarely use auto mode.

Well huh. Ours pulls the truck down from 138F on the sun to 68F no issues.
There is a bunch of thermal data available in service mode.

Wow really? My system seems much weaker than my previous ICE vehicle air conditioning. Mines a 2026, hopefully they didn't make any negative changes.

I've never had any issues heating or cooling no matter what the outside temp is. I wonder if you have a refrigerant leak?

I believe you should put in a ticket w/Tesla.
The A/C in all our 2023s+ (and heat) is REALLY good.
Before that it was total crap. But around 2022/23 it finally got good.

Change your hepa filter or make sure its installed properly maybe it’s the reason

I have noticed this but it’s the same with some other models we had, it’s not a powerful blow in your face fans.

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

I live in FL and when 100+ degrees outside seems like it is as good or better than any other vehicle I have had. I have a 25 from April

My AC works like a champ no issues, blowers cold before I can put the windows all the way down. For heat sometimes I have to put it on manual mode and force the air on the floor or my feet be cold.

100 degrees here and the inside of the truck gets very cold. Family complains.

90+ degrees here and the CT (06/2026 build) has no problem getting to 68 on auto.
Our Model 3 from 2022 could never keep up with the heat.

No problems cooling down even when stationary. Last week was hot and muggy in PGH (95°+) and I kept on saying to my wife "I love never getting into a hot car". After driving my stick shift (no remote start) black vinyl 09 BMW 335i for many summers...I feel like I moved from the Flintstones to the Jetsons.

No ceramic tint on my windshield, but I definitely have the metallic stuff in the roof glass since it rejects heat insanely well. Might look into near clear ceramic tint for the windshield.
