What Is A Heat Pump?

A heat pump is a machine that can move heat from one place to another to regulate the temperature. It can be used for both heating and cooling purposes, making it a versatile piece of equipment for any climate. Heat pumps operate on the principle of transferring heat, using a refrigerant cycle to absorb heat from the air or ground outside and release it inside the house or building.

In simple words, it can be likened to an air conditioner that can run in reverse. A soft lockout on a trane heat pump is a feature that protects the device from possible damage due to low refrigerant levels, dirty filters, and other problems, making it a reliable and long-lasting option for regulating the temperature in your home or business.
