Serviceability features: Features a convenient convertible airflow design and comes complete with easy power, control, and utility connections. These units feature a service-minded design with front-facing components for easy access and individual removable panels to reach different sections. This product line also features easy-access gas valves, propane conversion components, and slide-out blowers.

Noise-reduction features: Features industry-leading sound performance, particularly considering how much air these units can move. The upward airflow carries the normal operating noise up and away from the living area. The rigid top panel effectively isolates noise. The isolator-mounted compressor and rippled fins of the outdoor coil muffle the normal fan motor and compressor operating sounds. The uniquely formed base pan also aids in sound attenuation with its structural design.

IAQ equipment supported: External air filters are used for maximum flexibility in meeting customers’ indoor air quality needs, while standard protection helps prevent air intake, exhaust venting, or condensate blockage. The package moves a lot of air, which provides good airflow to help rapidly cool or heat a home. This high airflow performance is also what allows the package to overcome legacy ductwork layout challenges in older homes where some spaces don’t get enough air.

Thermostat compatibility: Compatible with most thermostats.

Replacement parts compatibility: Shares replacement parts with other models.
