Heat Pump Installation Guide

For many homeowners, heating and cooling represent one of the largest parts of household energy use. As technology improves, heat pumps are becoming an increasingly practical alternative to traditional heating systems.

Unlike systems that generate heat by burning fuel, a heat pump transfers existing heat from one place to another. In winter, it can draw heat from outdoor air and bring it into the home. In warmer months, the process can be reversed to provide cooling.

The result is one system capable of supporting year-round indoor comfort.

How Does a Heat Pump Work?

An air source heat pump works by transferring heat between the outdoor air and your home using a refrigeration cycle. Even when outside temperatures feel cold, there is still thermal energy in the air that the system can capture and use indoors.

The process relies on a continuous loop of refrigerant that absorbs, transports, and releases heat. A compressor drives the cycle, and a reversing valve allows the system to switch between heating and cooling modes. Here is a simplified view of what happens:

• The outdoor unit absorbs heat from the outside air — or releases it, when cooling.
• Refrigerant circulates through the system, carrying thermal energy between the outdoor and indoor units.
• The indoor unit distributes warmed or cooled air throughout the home.
• Smart controls monitor indoor and outdoor conditions to maintain comfortable, consistent temperatures.

Because the system moves heat rather than generating it from scratch, it can often deliver more usable energy to the home than it draws from the electricity supply. That efficiency advantage is one of the main reasons homeowners consider switching.

What Makes Heat Pumps Different?

Traditional heating systems typically do one job: they generate heat. A boiler burns fuel to warm water, a furnace burns fuel to warm air. Cooling, if present, is handled by an entirely separate system. Heat pumps take a different approach by combining heating and cooling into a single, integrated system.

They can also use energy more efficiently than many conventional heating technologies. Rather than converting fuel into heat, they transfer heat that already exists in the surrounding air, which typically requires less energy for the same level of comfort.
