Single-stage and two-stage heat pumps differ in their operation and offer distinct benefits::
Single-stage heat pumps have one output setting. They either are on or off, which might impact comfort and reduce efficiency.
Two-stage heat pumps can operate at both high and low speeds. The low-stage setting provides gentle heating or cooling for most days, while the higher setting kicks in during extreme temperatures, ensuring efficient temperature control in extreme climates. Two-stage heat pumps are generally more energy-efficient and offer more consistent temperature control improving home comfort.
