Overall Impression

Heating performance is a genuine strength for many owners. Several users say the AM09 heats rooms quickly and effectively, with one calling it excellent as a heater and another reporting their cold flat warmed up fast and happily. One user specifically said they love the heater despite other complaints. This suggests the heating element performs well when the unit functions correctly, making it a viable primary heat source for smaller spaces.

The 'cool' mode disappoints because it isn't real air conditioning. Multiple commenters express frustration that the cooling function is just unheated airflow rather than genuinely cold air, with some calling it bad marketing or an overpriced fan. Users specifically say it doesn't blow cold air, doesn't cool as much as hoped, or returned the unit immediately because it 'cools nothing.' This mismatch between expectation and marketing is a recurring complaint.

Long-term reliability is a serious concern for a chunk of owners. Several reviewers report the unit failing after a few years or even months, commonly citing the H2 error code that disables heating regardless of cleaning attempts. One user described going through three units that all failed within three years, while another called it a paperweight after four years. These complaints suggest durability issues that undermine the premium price for some buyers.
