Haier Pearl Premium Plus 3.5 kW sits at the top of Haier's domestic line on the Polish market — aimed at buyers who want a full feature set and a genuinely high energy class without paying for a Japanese premium brand. A+++ in cooling (SEER 8.5) and A++ in heating (SCOP 4.6) translate into noticeably lower running costs compared with A++ models at a similar installed price.
The model stands apart through its three-layer hygiene package: UV-C PRO sterilisation using a built-in LED lamp that generates both UV-C and VUV radiation, 56°C Steri Clean which heats the heat exchanger to a temperature that eliminates bacteria and viruses, and Self Clean which purges the evaporator using frozen condensate. COANDA Plus with 3D airflow, the I FEEL remote temperature sensor and a built-in Wi-Fi module with the hOn app round out the feature list. The unit works in heating mode down to -25°C outdoor temperature, and a drip-tray heater prevents condensate from freezing even in hard frosts.
The 4,623.60 PLN installed price covers the full installation by the LeoKlima team — with an authorised Haier partner warranty, nitrogen pressure test, vacuum evacuation and commissioning. A premium anti-vibration support under the outdoor unit, premium-class pipe insulation and gravity condensate drainage are standard. After commissioning the customer receives a technical handover report and a brief walkthrough of the remote and the hOn app.
Overview and positioning
Pearl Premium Plus sits directly above Revive Plus in Haier's range — it is aimed at customers who want a clearly higher energy class and an advanced hygiene package without giving up an accessible installed price. In the producer's hierarchy the Pearl Premium Plus series delivers A+++ in cooling and A++ in heating at a price close to the lower end of the Value & Quality segment, bridging the gap between the entry-level Revive line and higher-tier European models.
Haier continues to build its presence on the European market — the Polish branch provides a five-year compressor warranty, full service infrastructure and authorised-partner status for networks such as LeoKlima. Pearl Premium Plus is available in both Split and Multi Split configurations, so a single outdoor unit can serve several rooms. The 3.5 kW capacity covers cooling and heating of a room up to about 35 m² in the typical climate of the Warsaw area.
The colour choice is limited to a single variant — White Matt — which keeps the indoor unit visually unobtrusive against a light wall. The matte finish resists fingerprints and is easy to wipe clean. From LeoKlima's perspective Pearl Premium Plus is the model we recommend to customers who plan year-round use and care about keeping electricity bills low over the long term.
Cooling and heating technology
At the centre of the refrigeration circuit is a rotary compressor driven by a DC inverter. Nominal cooling capacity is 2.7 kW (range 0.8–3.6 kW); nominal heating capacity 3.1 kW (range 0.8–4.3 kW). The inverter modulates output continuously, eliminating the abrupt starts and stops of on/off systems and holding the set temperature to within 0.1°C using a PID control loop.
The unit runs on R32 refrigerant, which has a lower GWP than R410A and better heat-exchange efficiency per kilogram of charge. SEER 8.5 puts the unit in energy class A+++ for cooling; SCOP 4.6 corresponds to class A++ for heating. Nominal power draw is 0.71 kW in cooling mode (range 0.4–1.06 kW) and 0.83 kW in heating mode (range 0.4–1.39 kW) — resulting in very low annual running costs.
Heating operation extends to -25°C outdoor temperature — well beyond the capability of typical entry-level models. The drip-tray heater built into the outdoor unit prevents condensate from freezing during heavy frosts, ensuring uninterrupted winter operation. In cooling mode the unit works up to +43°C outdoors, covering the full Polish summer without limitation.
Comfort and air quality
Pearl Premium Plus delivers a three-layer hygiene package. UV-C PRO sterilisation uses a built-in 40 mm LED lamp emitting both UV-C and VUV radiation — a combination that can deactivate airborne contaminants and inhibit bacterial growth. The Texcell laboratory confirmed 99.991% effectiveness against SARS-CoV-2 in a 6.7 m³ sealed environment over 24 hours. The 56°C Steri Clean function (triggered from the app) heats the heat exchanger to 56°C for 30 minutes, destroying pathogens settled on its surface.
Self Clean cycles frozen condensate across the evaporator surface to dislodge accumulated dirt when defrosting. A dirty evaporator can cut cooling output by 15–30%; regular Self Clean cycles keep the unit performing at full rated capacity and reduce the risk of mould forming inside the indoor unit. A washable mechanical filter traps pollen, dust and larger particles before they reach the heat exchanger.
3D airflow is delivered through horizontal and vertical louvres driven by stepper motors, producing 670 m³/h. COANDA Plus directs the jet toward the ceiling in cooling mode — air then drops along the walls, bypassing people in the room — or toward the floor in heating mode, where warm air collects at floor level and rises naturally. I FEEL reads temperature at the remote rather than near the ceiling, so the unit regulates to the actual temperature at the user's location.
Controls and Wi-Fi
The built-in 2.4 GHz Wi-Fi module connects to the hOn app — Haier's shared platform for air conditioners and home appliances. Setup consists of pairing the unit with a router via a QR code in the Android or iOS app. Once paired, the air conditioner is accessible remotely from anywhere: you can check room temperature, change operating mode, set a weekly schedule or trigger UV-C PRO sterilisation without leaving your seat.
The hOn app provides every operating mode: cooling, heating, dehumidification, ventilation and auto. Available presets include ECO (reduced power draw), QUIET (lowest achievable noise), Sleep (night mode with automatic temperature drift) and Turbo Cooling (rapid room cool-down). The app integrates with Google Assistant and Amazon Alexa for voice control.
A wireless remote is included as standard, and the indoor unit has a hidden LED display that shows operating status and fault codes — invisible when the unit is off. An optional wired controller can be added (requires a WK-B converter), along with an ON-OFF card for hotel and commercial environments. AUTO RESTART recovers the last settings after a power cut.
Design and build
The Pearl Premium Plus indoor unit measures 805 × 292 × 200 mm (W/H/D) and weighs 8.6 kg — a compact rectangular body in matte white with no decorative interruptions across the front face. The White Matt finish does not collect visible fingerprints under raking light, keeping the unit inconspicuous between cleaning sessions. The hidden front LED display contributes to the minimalist look.
The outdoor unit measures 800 × 553 × 280 mm and weighs 28.5 kg. Its integrated construction unites the base, drip tray and casing frame into a single assembly that limits vibration transmission and simplifies installation. A valve cover encloses both the electrical terminal block and the service valve, giving the connection area a tidy and secure appearance. The powder-coated steel casing handles many years of Polish outdoor exposure without corrosion.
Refrigerant pipework can be routed in either direction — left or right — providing flexibility when planning the pipe run through or along the wall. Standard flared copper connections mean the unit is compatible with any authorised service company; there are no proprietary fittings. Easy access to the indoor fan motor keeps service time and cost low.
Installation and service
The 4,623.60 PLN installed price covers a standard fit — outdoor unit on the building's external wall up to 5 metres from the indoor unit, copper pipework in premium-class insulation (Armacell or Ebrille), gravity condensate drainage to the sanitary stack and electrical connection to the nearest socket. A nitrogen pressure test, vacuum evacuation and commissioning with a customer briefing are all included.
LeoKlima fits premium anti-vibration brackets under the outdoor unit as standard — this removes vibration from the building structure and extends compressor service life. Every project is preceded by a free technical site visit during which the installer checks the pipe route, electrical conditions and the best location for the outdoor unit. For flats on upper floors, mounting on the external wall rather than the balcony railing is the recommended approach.
The unit is covered by the authorised Haier partner warranty — five years on the compressor and two years on all other components. After commissioning, the customer receives a pressure-test report with refrigerant charge levels and full technical documentation. In-season (June–August) response time is up to 48 hours; out of season we typically respond within 24 hours of a report. Annual cleaning of filters, evaporator and condenser is essential for maintaining A+++ class performance throughout the unit's service life.
Who this model is for — summary
Pearl Premium Plus 3.5 kW suits customers who want year-round use — summer cooling, winter heating as a primary or supplementary source — and care about keeping running costs low. A+++ in cooling and the full UV-C PRO, Steri Clean and Self Clean hygiene stack set it apart from standard value-tier offerings. It works well in a bedroom, a living room up to 35 m² or a small study, where 18 dB(A) night operation will not disrupt sleep.
For buyers with a higher budget who prioritise acoustics and refined aesthetics, Haier FLEXIS Plus or models from the Toshiba Shorai Edge line are worth considering. If price is the overriding factor and hygiene features are secondary, Haier Revive Plus remains a solid alternative at a lower installed cost. Pearl Premium Plus occupies the middle ground: it delivers meaningfully more than Revive Plus at a price close to the lower boundary of the premium segment.
The best first step is booking a free technical site visit — a LeoKlima specialist will assess room volume, sun exposure, building insulation and recommend the model best matched to the actual conditions. Contact via the form on the site or by phone on 502 010 010. The durability and efficiency of any air conditioner depend as much on installation quality as on catalogue figures — which is why trusting the install to an authorised team with full handover documentation matters.

Frequently asked questions
How does Pearl Premium Plus differ from Haier Revive Plus?
Pearl Premium Plus achieves a higher energy class — A+++ in cooling (SEER 8.5) versus A++ in Revive Plus — and adds a full hygiene stack: UV-C PRO sterilisation, 56°C Steri Clean and Self Clean. Heating operates down to -25°C (Revive to -15°C), and the drip-tray heater ensures trouble-free winter operation in severe frost.
Does UV-C PRO sterilisation run continuously during normal operation?
UV-C PRO can be switched on or off independently of the air conditioner's operating mode — from the remote or the hOn app. The 56°C Steri Clean heat-exchanger disinfection cycle is triggered manually from the app and takes approximately 30 minutes.
Can this unit heat a flat through a Polish winter?
Yes — the heating operating range extends to -25°C outdoor temperature. The drip-tray heater protects the outdoor unit from condensate freezing during frost. In Polish climatic conditions the unit can serve as the primary or supplementary heat source for most of the heating season.
