Whether it’s blazing hot summers, chilly winters, or humid seasons, this system is built to keep your home comfortable. As a heat pump, it can reverse operation to extract warmth from outdoor air, efficiently heating your space even in cooler temperatures.

Each air handler provides directional airflow, ensuring consistent and even temperature control throughout the room. Need instant cooling? Activate manual forced cooling mode with the hidden button under the front panel, ideal for post-installation testing or maintenance.
