Positive. I’ve investigated the coolant pump before because I can hear it when the car is charging if I’m really quiet and I’m standing next to the car. I definitely can’t hear that from inside the house. This was the heat pump - it had that distinct heat pump ‘whir-whir-whir’ and was quite loud.
I’ll keep an eye on it and try to get a video if it does it again. It was definitely strange. It’s been a very cold winter, so I figured it was something temperature related.
