How Does a Heat Pump Work?
Even in cold temperatures, heat still exists in the air.
The heat pump refrigerant absorbs the heat from the outside air, compresses it making it even hotter, and sends it to the coil.
The coil heats up from the heated refrigerant passing through it and conditions the air as it is blown across the coil.
As the passing air grabs the heat from the coil, the refrigerant inside the coil cools down and is sent back to the heat pump to absorb the heat from the outside and repeats the process.
As the temperature outside drops, it is harder for the heat pump to extract enough heat to keep up with the home’s heating needs.
When the heat pump cannot keep up the home’s heating needs, it has reached its “Balance Point” and needs backup heat sources, such as resistant heat strips to keep the home comfortable.
