Hisense 1.5 Ton Full DC Inverter AC AS-18TW4RMATD01BU

Hisense 1.5 Ton Full DC Inverter AC AS-18TW4RMATD01BU is aimed at households that run cooling for long stretches, day and night, and care most about what the meter reads at the end of the month. It delivers 18000 BTU/h (5275 W), which suits a 120–160 sq ft bedroom or living room.

This is a genuine inverter unit: the compressor is a rotary inverter type, so once the room reaches temperature it slows down instead of switching off and slamming back on. That keeps the room temperature steady and cuts the repeated start-up surge. Hisense rates this Hisense Full DC Inverter AC at up to 65% energy saving, and its EER of 3.20 is the highest of the three Hisense 1.5 ton models we stock. Rated input power is 1650 W at 7.3 A.

If you are weighing a 1.5 Ton Inverter AC 18000 BTU against a fixed-speed model of the same tonnage, this is where the difference shows. A fixed-speed unit is fine for a couple of hours a day, but for eight to ten hours of nightly use a 65% energy saving air conditioner of this type will show a visibly smaller electricity bill, and the 12 year compressor warranty reflects how much less start-stop stress the compressor takes.

It is an R32 inverter split AC carrying 0.710 kg of refrigerant, with a copper tube evaporator and copper tube condenser, both finished with golden hydrophilic fin to resist corrosion in humid coastal air. Refrigerant leak detection is built in. Indoor noise is 40 dB at mid fan speed and the outdoor unit measures 56 dB. Auto Restart returns the unit to its previous settings after load-shedding, and temperature can be set from 16°C to 30°C with a 24 hour timer, sleep operation, super function, washable PP filter and both auto swing louvers.

Important Usage Instructions

• Have the indoor and outdoor units installed by a trained technician and keep the connecting pipe run within 4 metres.
• Let an inverter unit run steadily rather than switching it on and off; that is where its saving comes from.
• Set 24°C to 26°C with the fan on auto, and keep doors and windows shut while cooling.
• Rinse the washable PP filter every two to three weeks in summer so airflow and efficiency stay up.
• Keep the outdoor unit clear of obstructions and away from standing water, and use a stabiliser if your line voltage swings badly.
