Heating is a big drain, to the point that Tesla has now included a heat pump in the Model 3 and Model Y now. AC usage actually has minimal impact. Another surprise for first time EV owners is that there is a 12v accessories battery in Tesla EVs in addition to the main battery. The 12V is used for the audio systems, windows, etc. like an ICE based vehicle. When the car is "sleeping" so to speak, if the 12v battery needs charging the car wakes up and transfers energy from the main battery to the 12v accessory battery.
