TCL 3.5kW Portable Air Conditioner vs Dimplex 3.5kW Portable Air Conditioner with Wi-Fi

What you'll actually notice

TCL TAC-12CPB-MZ and Dimplex DCP35FS are both 3.5kW cooling-only portable air conditioners, so headline cooling capacity does not separate them. The differences show up in ownership and day-to-day use.

TCL gives you a three-year warranty and unusually clear acoustic labelling: 51–53dB(A) sound pressure plus 65dB(A) sound power. Dimplex gives you built-in Glen Dimplex Connect Wi-Fi and a much lighter 22.5kg body, compared with TCL at 27kg.

That makes the choice straightforward once 3.5kW is the right capacity tier: TCL leans toward longer written cover and clearer noise specifications; Dimplex leans toward easier movement and connected control.

Both still require an outdoor exhaust route. If heating is mandatory, skip both.

What changes the choice

Capacity is effectively tied

Both products are rated at 3.5kW cooling. Once that capacity class fits the room's actual heat load, there is little value in trying to manufacture a winner from the cooling number.

Manufacturer room-size guidance can help orient the decision, but it is not a standardised cross-brand test. Sun load, glazing, insulation, ceiling height and climate still matter.

Dimplex is lighter and connected

Dimplex weighs 22.5kg, while TCL weighs 27kg. A 4.5kg difference matters if you genuinely roll the unit between rooms or regularly move it for storage. Dimplex is also narrower in the published cabinet dimensions.

Dimplex also supports Glen Dimplex Connect Wi-Fi/app control. TCL does not have verified built-in Wi-Fi on this exact Australian model. If app control is mandatory, that is a meaningful reason to choose Dimplex.

TCL gives you longer written cover and clearer noise data

TCL publishes a three-year warranty; Dimplex lists two years domestic warranty. That describes the period of manufacturer cover, not a guaranteed difference in service life.

For noise, TCL publishes both sound pressure and sound power with clear labels. Dimplex publishes ≤65dB(A), but the available specification does not identify a directly comparable acoustic metric. That means TCL's noise information is easier to interpret. It does not prove TCL is quieter.

Dehumidification and exhaust do not create a winner

Both are rated at 1.7L/h dehumidification. Dimplex also describes self-evaporative operation, which can reduce routine water handling in some conditions but should not be read as “never needs drainage”.

Both include window/exhaust hardware and require heat to be exhausted outdoors. An unsuitable window or hose layout rules out both before Wi-Fi or warranty becomes relevant.

What this means: once 3.5kW is established as appropriate, this is mainly a choice between TCL's warranty/acoustic-documentation strengths and Dimplex's lower weight/Wi-Fi strengths.

Switch when: move to Dimplex when app control or regular movement is genuinely important. Move to TCL when the extra year of written cover or more clearly labelled noise data matters more.

The practical choice

Think about how the unit will actually live in the room. A portable AC that stays in one position all summer makes Dimplex's 4.5kg weight advantage less important. A unit that moves between a bedroom and living area makes that difference much more tangible.

Likewise, Wi-Fi is valuable only if you intend to use it. If a remote control and timer are sufficient, TCL's conventional control set may be perfectly adequate.

For noise-sensitive use, do not compare Dimplex's ≤65dB(A) headline with TCL's 51–53dB(A) sound-pressure range as if they were the same measurement. The safer conclusion is simply that TCL's published acoustic information is more clearly classified.

When to choose TCL TAC-12CPB-MZ

Choose TCL when 3.5kW cooling fits the room and you value a three-year written warranty.

It is also the better documented option if acoustic specifications are part of your screening process. TCL's sound-pressure and sound-power figures are labelled separately, which makes them easier to interpret without inventing a cross-metric comparison.

Choose it when 27kg is acceptable, app control is not essential and the supplied window exhaust arrangement works in your room.

When to choose Dimplex DCP35FS

Choose Dimplex when built-in Wi-Fi and the 22.5kg body materially improve the way you will use the appliance.

That lower weight is especially useful when the unit will move between rooms on the same level. The connected-control option also gives Dimplex a clearer role for shoppers who want app-based scheduling or remote operation.

Accept the trade-offs: the domestic warranty is two years, and its published ≤65dB(A) number should not be ranked directly against TCL's labelled sound-pressure figures.

Choose neither when

Choose neither if you need reverse-cycle heating. Both are cooling-only models.

Choose neither if the room cannot support a practical outdoor exhaust route or if the window kit cannot be made to work with the actual opening.

If quiet overnight operation is the dominant requirement and you need a precise numerical cross-brand ranking, the available Dimplex acoustic labelling is not strong enough to support one. In that case, widen the shortlist rather than pretending the numbers are directly comparable.

PIQSY conclusion

TCL is the warranty-and-documentation choice; Dimplex is the lighter connected-control choice.

Choose TCL when the three-year warranty and clearly labelled acoustic specifications matter more than app control and lower weight. Choose Dimplex when built-in Wi-Fi and a 22.5kg body better match your room-to-room workflow.

Capacity is tied at 3.5kW, so do not let a temporary price difference distract from those durable ownership differences. Confirm exhaust fit first, then compare current delivered price and availability.
