How much range an A/C or heater uses is tied into your speed, duty cycle, passengers, and driving habits.
The best you can figure, is what the peak draw is on the A/C unit. Probably less than 5kW. This can be tested on cars with a kW meter. Sit idle with A/C off and record the value. Turn A/C on max and record the highest value. Subtract.
Example: Say idle is 1 kW, then AC Max is 6 kW, your AC uses 5kW (but probably less).
So every hour the compressor runs, it takes 5 kWh of your battery.
So if you are driving at 75 mph solo and the compressor is running 50% of the time, it's wildly different than 25 mph with 4 people in the car running 100% of the time.
