Absolutely true - efficiency drops. Electrical consumption also drops if your heat exchanger can't scavenge enough heat from the air to vaporize your refrigerant. The compressor must slow down.
Or as I pointed out - you can activate a backup heat source which causes a huge spike in electrical usage. Probably better than freezing however.
- thehappypm 4y agoMost heat pumps don’t have a backup built in anymore, though. I have 2 (LG and Mitsubishi) and neither has a resistive backup built in.
- timbit42 4y agoMy heat pump is 11 years old and doesn't have a resistive heater. I thought resistive heaters were a new thing. Many people in the Northern US and Canada need some kind of backup and a resistive heater in the heat pump would be a selling point for many.
