CENTEK CT-65A09 / CT-65A09 air conditioner

Our verdict on the CENTEK CT-65A09

The indoor unit delivers on the promise: a two-row heat exchanger and, by our measurements, 0.22 m² of copper tube surface area with a 7 mm diameter—almost twice our minimum benchmark of 0.13 m², while competitors at this price point typically stick right to that minimum. The outdoor unit, however, shows an anomaly: the exact same 0.22 m² area, but with thinner 5 mm copper and a radiator only 12 mm thick. Normally the outdoor unit should be about 30% larger than the indoor one—but here they’re the same. That means the compressor will have to work under strain, and the owner will need to clean the outdoor module regularly. All the “saved” copper ends up right here, and this one-to-one sizing essentially rules out heating.

A JMCC Class A compressor with index 95 is a confident choice for a 2.8 kW rated unit. The maximum line length is 20 meters—above the market average (typically ~15), a real installation advantage. But this is an on/off unit, so it doesn’t make—and cannot make—a serious claim to cold-weather operation.

The remote, built on the AUX platform, is done properly: Russian labels, color-differentiated buttons, dedicated backlit mode keys, and instant response. There’s no Wi‑Fi, apps, or presence sensors—this is an honest, straightforward control tool. The louvers are adjusted manually, with only two sections. Filtration is limited to a coarse mesh: no fine filtration, no UV lamps, no ionizers, and no self-cleaning.

The manufacturer claims 23 dB—we measured 35 at the lowest fan speed, slightly above our average of 33 dB, but within normal limits for a non-inverter. The fan has five speeds, which is generous for the budget class. It also handles reduced supply voltage confidently: at 150 V it runs at ~4.2 A; when voltage sags to 100 V it shuts down and then restarts on its own once voltage returns—useful for southern grids.
