What does a heat pump do?

A heat pump functions primarily by transferring heat from one location to another, utilizing the principles of thermodynamics. In heating mode, a heat pump extracts heat from the outside air or the ground and transfers it indoors, even in cooler temperatures, providing heating for a space. Conversely, in cooling mode, it reverses the process by removing heat from the indoor environment and discharging it outside, effectively cooling the space.

This dual functionality distinguishes heat pumps from other HVAC systems that typically only perform a single function, such as only heating or cooling. Instead of generating heat directly like a furnace or only providing chilled air like an air conditioner, heat pumps excel in their ability to efficiently move thermal energy where it is needed, making them versatile and energy-efficient options for temperature regulation in residential and commercial settings.
