    Feature Request - Eco-Mode Air Conditioning

    All Models: Eco-Mode - Reduce consumption of the Air conditioner by about half. Heater Toggle - Turn off the heater for the air conditioner to draw fresh air instead. Recirculation timer - turn off recirculation after 15mins to avoid high condensation. After using the Polestar 2 for three...

    Heat off control (like AC off control) or have a temperature range setting

    Having a single temperature setting means that either the heat or AC is on all the time. Being able to set a range where one gets ventilation only without heat or AC would be helpful in temperate conditions, or when the AC is on but the temperature drops in the evening. In the latter case...

    2023 MY Not Blowing Cold Air

    The temperature in town yesterday was a whopping 103 degrees. I had to go to a store and was there about an hour. When getting back to the car, the temperature on the dash said 114. I turned on the Aircon and was driving home. Set the TEMP inside to LOW. All the way home it was blowing cool...

    2019 M3 Rear Vent blows warm air when low-level cooling is required

    My 2019 Model 3 SR+ seems to have an issue with blowing warm air to the rear vent when it should be cold. This issue happens when mild cooling is required, for example, outside 76°F and inside temp set to 72°F. The front vents will blow cold, but the rear will blow warm. If air recycle is on...

    Intermittent AC issues

    I have a MYP on software 2023.20.9 and have notice that on some drives, my ac will not blow below 64 degrees (using a temperature gun shooting directly at the vents) even after driving for 30+ minutes when temp is around 100 degrees outside and temperature set at lowest setting. I know this is...

    Tesla Software Irritations

    Hi everyone, I'm new to this forum and am hoping to be able to learn more about my Model Y and - in particular - some tips of optimal configuration of the software. Given I'm in Australia (Sydney), my experiences might be a little different from others, but I'd appreciate any thoughts people...

    Excessive A/C energy usage

    Drove 109 miles in MYLR yesterday @ average 100deg normal WPM for this round trip is 240 yesterday 309. Energy screen showed 51.5% of battery used for drive of which 15% was consumed by climate, thats 29%! Drive time was approx 3 hrs Climate set to auto 73 deg rear/passenger vents on. I have...

    2023 M3 air conditioner using 70% of energy

    We live in Phoenix, so it is hot, our 2023 M3 standard range at 80% was getting about the range shown 223 miles during the winter. In the summer we are getting less than half of that, we now get less than 100 miles. The energy app shows that all the energy is lost under climate (only occurs...

    AC Blowing Hot Air

    Hi Everyone I have been having problems with the AC since few days now. It has been fixed for a sensor problem last year but not sure if it is the same problem coming again. Unfortunately, my MS2020 went out of warranty only few weeks ago 😪 The AC suddenly and after a recent system update...

    A/C only works in Park. Hot smelly air when driving

    I have a 2016 Tesla Model X and for the past few weeks my A/C only works if the car is in park. When the car is in drive, it blows hot air that smells like dirty laundry. In park it blows cold A/C air. It has consistently followed this pattern. There have been software updates since it started...

    New wrinkle in HVAC

    After a week of noticing the air conditioner, here in sunny SW Florida, seemed to be intermittently blowing warmer than it ought to have, we got a notice on the screen saying HVAC system needed dealer service, and stopped working all together., this on last Friday evening. Research here talked...

    Late 2021 onwards MIC Model 3s Have poor/faulty air conditioning from factory

    After 4 Months of sending my Model 3 (December 2021, china factory) back to the service center for blowing on my knees and being told that "nothing was wrong" and everything being correct in the dash, it turns out that I was just the first of people noticing that the Model 3 with the new Heat...

    HVAC Cooling Performance Degraded

    With spring arriving in the Midwest and the warmer temperatures, I've noticed that my 2018 Model 3 is experiencing issues keeping the cabin cool over a few drives in the last 3 weeks. During the past two summers I've kept the AC around 70-72F in the summer with no issues. This year I'm having...

    MAJOR breakthrough in HVAC control (heating with single occupant)

    Okay, so I'm an eco nerd and hate the impact that driving in the winter has. I've had my Model 3 through 4 winters now and just today (with the help of the Scan My Tesla app) did I discover that you can go manual temperature control, split the HVAC for left/right controls, set the passenger side...

    HVAC Control - for those over 50

    30 years ago, most houses had a thermostat with two settings: How LOW the room temperature will go before the HEATER kicks on. How HIGH the room temperature will go before the A/C kicks on. Yes, you set a temperature range. There were two slider adjustments to limit "how warm" and "how cool"...

    Pro Tip: Setting the climate 71F or lower uses less energy in hot weather

    With hot Summer weather approaching, I thought to point out that setting the climate above 71F consumes about double the amount of energy. Intuitively, the thinking is setting the climate warmer means the a/c runs less often. The reality is that in Teslas, it creates heat to get the air to the...

    How good is YOUR Climate Control - Temperature Consistency

    Okay, I spent a while scouring for some information and haven't found any threads on this. I have had a temperature regulation issue and I am trying to decide if I just need to live with it or keep pushing Tesla Service on this. It mainly seems to occur in the first 10-20 minutes of a drive. I...

    Air conditioner cutting out

    Im thinking this is a service call. Hoping a member can test to make sure its not how its supposed to function. This happens more apparently when the car is hot. so turning the thermostat all the way to low from a normal temperature will increase the fan and cooling. It will work fine for 3-5...

    Tesla should show how much energy is going to heating

    A main reason range is significantly reduced in cold weather is heating the passenger compartment and the battery. It would be nice if Tesla would show energy usage of this heating and how much it is effecting range. This can help people appreciate the issue and perhaps get them to reduce...

    Don't want heater on, want vent

    Afternoon is still warm enough to require AC. Next morning I keep forgetting and after about 10 minutes of driving I realize heater is on. It is around 62 degrees out which is lower than the 72 degree setting in the car. In that scenario I don't want heater! I want vent. Keep the car cool until...
