heat pump

After some conflicting info on heat pump efficiency/longevity I ask the experts here: Claim 1: Running the heat pump at low fan setting (comfort aside) is more efficient as less air needs to be heated cooled. Some observations in servicemode where lower fanspeed equals lower compressor rpm...

Hello my dear Tesla owners, I want to share my first experience on owning a Tesla. Buying a new car is a new experience and for some it can be a troublesome exercise and for some it can be a breeze. For me leaning towards an EV, Tesla model Y, was a big step and from there on everything was...

Hi community, hope someone can help me with this before I can drop the car off at a service center. Today i noticed a strange howling sound coming from the front / trunk (heat pump possibly?). It happened after approx. 1 hr of driving and repeated every minute or so. Has anyone heard this sound...

Hey y’all! For a while now, my 2021 TM3 (heat pump) has been experiencing heating issues by throwing error codes every so often, disabling cabin heater. Out of warranty replacement from tesla is charging $2,000 USD. A workaround I discovered to reset the system is to disconnect 12v and negative...

Hi, My model Y AC stopped working when I’m driving long trip, I’m driving on highway with 104 degrees interior temperature today, and feel like dying. Also my heat point is activated the whole time, making loud noises the whole day time. The earliest appointment available is 17th, have anyone...

Hey everyone, I created a couple videos to try to explain the Octovalve system in depth and what makes it so special. Hope it can help some of you understand the system better. Still new to this, so I'd appreciate any feedback anyone wants to provide. Thanks! Octovalve: The Holy Grail of...

2021.44.30.6 is rolling out to vehicles now and UK owners are now receiving the update. There are no release notes for this version. There were unconfirmed reports that the heat pump issues were being fixed. It looks like they haven't been from the reports that I've been seeing. If you had...

This is primarily directed to those in cold northern cold environments who have/had older Model S and now have the refresh. With the refreshed Model S, how are you finding the heat with the heat pump, especially when it gets colder? Is it noisy? Is it getting the job done? How is are you finding...

Hello Community, I have quite a loud rattling sound coming from the front wheel well / frunk area that seems to be AC / heat pump related. It occurs mostly when it is hot outside and/or the AC is producing cool air. I also get the rattle one or two times quite often when I open the driver...

Hello, I'm new to this forum and I have a question for Tesla Model 3 owners. Recentry I wanted to experience a super fast charging session (LG Battery - yes I know) at a V3 SC. So, I made sure I got there with warm battery and low state of charge. I got extremely good speed at the starting of...

So, my car just got this issue. It seems to be fairly quick to diagnose (besides not actually feeling heat) since the climate screen will have the "Climate Keeper is unavailable..." message, and you won't be able to turn on Dog or Camp mode, etc. You also won't be able to use the remote climate...

Is there any data out there comparing the earlier M3, no heat pump, with the new M3 with heat pump for efficiency and range in cold weather?

As an imminent MY customer, I've been paying attention to the various threads about Heat pump problems. At the moment these are mostly stories of inoperative cabin heating/defrosting in extreme winter conditions. However, there are also older threads floating around about weak or occasionally...

So I was wondering how the heat pump would perform in extreme cold and today I got to find out. I put on about 200 kms today and while I was driving around the city the heat worked as expected, it kept us toasty warm. However, this evening I went out on the highway and the combination of -35 C...

Hi Everyone, I have a 2021 TM3. the one with the heat pump ;-) This week end I was on a road trip with my family, We went to Ottawa (200km from Montreal). On saturday every thing went well but today it was a nightmare. This morning, I entered the adresse for a supercharger, the car started to...

Took delivery of my MSM Model Y on 12/30. This morning when wife is backing out of the garage the car is blowing super loud noise, literally sounds like someone is sitting in the frunk blowing a conch. Seems coming out of the front intake vents. Is it possible this is heat pump related? I am in...

Anyone else noticing that when the temperature is below freezing that the heater takes a lot longer to warm the car? This morning it took close to 30 minutes before the climate even approached the right level (while also still attached on the charger). Comparatively, my Model S with resistance...

EPA test docs for the US 2021 SR+ have been published. (EPA datafile and EPA new car website not yet updated though.) https://iaspub.epa.gov/otaqpub/display_file.jsp?docid=51461&flag=1 -> It has a heat pump (heat pump confirmed!) -> Battery capacity seems similar to that of the 2019, though...

Suddenly our heat is not working in winter. It is exact same as described here. Anyone else?

I have a Model Y performance that is having heat pump issues after taking it to my nearest service center to have the retrofit heat pump cover (AC Compressor Acoustic Cover, Model Y Part #: 1502213-00-A, I think) installed. I must say that I'm not real happy with the service there and would...

"I did notice that it didn't feel 70 in the car" was iTesla's comment about the cold portion of his 1000 mile run last week when asked "At what temperature did you notice the heat pump not keeping the interior of the car warm? I'm in Minnesota and It has to work in pretty cold temps here."...
