Quick Answer: The best De’Longhi air conditioner in 2026 is the Pinguino Arctic Whisper Extreme PAC EX390LVYN — a 14,000 BTU ASHRAE portable whose Cool Surround remote carries its own temperature and humidity sensors, so the unit cools to where you are sitting instead of to the air beside itself. No other mainstream brand offers that. The PAC EX390LN DeLuxe is the value pick in the same cooling class, and the compact PAC EM375WRC (6,900 BTU) is the bedroom-sized option. One thing to know before you buy: every Pinguino is single-hose, none use an inverter, and the “500 sq ft” and “700 sq ft” badges come from the old ASHRAE rating, not the DOE number — size from the SACC figure instead.
De’Longhi is the odd brand out in portable air conditioning. It is an Italian appliance company best known for espresso machines and oil-filled radiators, it has never sold a window unit in the US, and it competes with Midea and LG without an inverter compressor or a dual-hose design anywhere in its catalog. And yet the Pinguino line keeps selling, because De’Longhi solved a different problem than everyone else did. Here’s the full lineup decoded, the models worth buying, and the one number on every De’Longhi box that you should not trust.
The 700 sq ft problem, in De’Longhi’s own numbers
Start with the honest part: De’Longhi publishes more than most of its competitors do. Its listing for the Pinguino Plus PAC EL290HLWKC gives you both capacity standards side by side — 8,700 BTU SACC and 14,000 BTU ASHRAE. Most brands quietly print one number and hope you don’t ask which.
Then it attaches a coverage claim of 700 sq ft — and that claim is built from the 14,000, not the 8,700.
Here’s why that matters. Since 2017 the DOE has required portable air conditioners to be rated with SACC (Seasonally Adjusted Cooling Capacity), which measures a single-hose unit the way it actually runs: with the infiltration penalty included. The older ASHRAE 128 number ignores that. ENERGY STAR and the DOE both publish a sizing rule of roughly 20 BTU per square foot, and applied to the real number, 8,700 BTU SACC covers about 435 sq ft — not 700.
This isn’t a De’Longhi-only sin, but De’Longhi makes it unusually easy to catch, because both numbers are right there. Compare how much capacity survives the switch to the DOE standard across the category:
| Model | ASHRAE | DOE / SACC | Capacity retained | Hoses |
|---|---|---|---|---|
| Midea Duo MAP14HS1TBL | 14,000 | 12,000 | 86% | Dual (hose-in-hose) |
| LG LP1419IVSM | 14,000 | 10,000 | 71% | Single (inverter) |
| Whynter ARC-14S | 14,000 | 9,500 | 68% | Dual |
| De'Longhi PAC EL290HLWKC | 14,000 | 8,700 | 62% | Single |
That spread is the single-hose penalty made visible, and it is the strongest argument for reading our dual-hose vs single-hose comparison before you commit to any portable. It does not make the De’Longhi a bad machine. It makes the badge on the box a bad sizing tool.
The rule: buy a De’Longhi for a room about 60 percent the size De’Longhi tells you it covers. At that size, these units are quiet, stable and pleasant to live with.
What De’Longhi actually does better: Cool Surround
Every brand claims a comfort feature. De’Longhi’s is real, and it is the reason to pick a Pinguino over a cheaper competitor.
Real Feel is the baseline version, and it appears across most of the line. Instead of chasing a raw temperature, the unit factors in humidity and targets how the room feels, dehumidifying rather than over-cooling to get there. De’Longhi says the logic saves up to 30 percent in energy consumption — a manufacturer claim, so treat the number as directional, but the behavior is genuinely more comfortable in a humid climate.
Cool Surround, on the flagship PAC EX390LVYN, is the one that matters. The remote itself contains temperature and humidity sensors, so the air conditioner regulates conditions at the remote’s location, not its own. Put the remote on your desk or nightstand, and the unit stops cooling the corner it happens to be standing in. When Reviewed tested the PACEX390LVYN, the sensing remote was the feature it led with — and in its test the unit pulled a room from about 80°F to a 70°F target in under an hour, with most of the drop in the first 10–15 minutes.
Every portable AC has a thermostat. Only this one has a thermostat where you are.
The other line-wide feature is Arctic Whisper, which De’Longhi describes as up to 50 percent less noise than its previous models. Read that carefully: it is a relative claim against De’Longhi’s own older units, and the company does not publish a dB figure for most Pinguino models. If a specific decibel number is what you need, our quiet AC guide covers units that actually publish one.
The De’Longhi model-number decoder
Pinguino model numbers look intimidating and are simple once you see the pattern.
| Segment | Means | Example |
|---|---|---|
| PAC | Pinguino Air Conditioner — on every model | PAC EX390LVYN |
| EM | Compact entry line, ~500 sq ft badge | PAC EM375WRC |
| EL | Pinguino Plus, mid-range | PAC EL290HLWKC |
| EX | DeLuxe / Arctic Whisper Extreme flagship | PAC EX390LN |
| 290 / 370 / 375 / 390 | Size and generation class; 390 is the largest | 390 = 14,000 BTU ASHRAE class |
| HL | Adds a heating mode (4-in-1 instead of 3-in-1) | EL290HLWKC heats; EX390LN does not |
| -3ALBK / -6ABK / -6ALLG | Color and retail channel only — same machine | Ignore everything after the dash |
The practical takeaway: match the part before the dash. A PACEX390LVYN-6ABK and a PACEX390LVYN-6AWH are the same air conditioner in different colors, and price differences between the two are a retailer artifact, not a spec difference.
The De’Longhi air conditioners worth buying in 2026
Best overall: De'Longhi Pinguino PAC EX390LVYN (Arctic Whisper Extreme)
- The Cool Surround remote's built-in temperature and humidity sensors are the only feature in this category no competitor copies — the unit cools to your chair, not to itself.
- Reviewed measured a drop from roughly 80°F to a 70°F target in under an hour in its test room, with most of it inside the first 15 minutes.
- Real Feel humidity logic means it dehumidifies instead of over-cooling, which is why it feels comfortable at a higher set point.
- Size it for a real room of about 400–450 sq ft, not the 700 on the box.
Don’t sweat the heat wave — Prime delivers an 83-pound portable AC like this to your door in two days, and you can try it free for 30 days.
One caution on this model that has nothing to do with cooling: at 83.33 pounds it is among the heaviest portables sold, and Reviewed flagged stair transport as its main drawback. Casters make it easy to roll across a floor and no easier to carry up to a second-story bedroom. Buy it for the room it will live in.
Best value: De'Longhi Pinguino PAC EX390LN (DeLuxe)
- Same flagship cooling class as the EX390LVYN without paying for the Cool Surround remote — the biggest price-to-performance step in the line.
- De'Longhi claims up to 17 percent better efficiency than the previous generation, plus improved sound insulation and motorized airflow.
- No heating mode: the missing HL in the model number tells you that before you read a single spec.
- The right pick if you want De'Longhi's build and quiet operation and will set the thermostat once and leave it.
Best for bedrooms and small rooms: De'Longhi Pinguino PAC EM375WRC (Compact Arctic Whisper)
- The compact EM chassis is the Pinguino you can actually move between rooms, and the one that fits beside a bed without dominating it.
- Uses R32 refrigerant, which De'Longhi markets as its eco-friendly gas — the same lower-GWP refrigerant the industry is standardizing on.
- Apply the same discount to the badge: 6,900 BTU is honest coverage for roughly 340–350 sq ft, which is a real bedroom.
- Arctic Whisper noise reduction matters most here, because this is the unit most likely to run while you sleep.
If the bedroom is the whole reason you’re shopping, compare this against the rest of the field in our best portable AC for bedrooms guide before you decide — noise floor and thermostat behavior matter more there than raw capacity.
Most transparent spec sheet: De'Longhi Pinguino Plus PAC EL290HLWKC
- The only Pinguino that publishes its SACC number next to its ASHRAE number — which is exactly what makes it easy to size correctly at about 435 sq ft.
- 4-in-1: cools, heats, dehumidifies and runs as a fan, with Real Feel humidity control across all modes.
- At 70 lb it is 13 pounds lighter than the EX390LVYN flagship, which you will notice the one time you move it.
- Caveat: De'Longhi publishes no heating BTU and no heat type for the HL models — see below before you buy it for heat.
The HL heat models: what De’Longhi doesn’t publish
De’Longhi sells several 4-in-1 Pinguinos that heat as well as cool, marked by HL in the model number. It does not publish a heating BTU rating or a heat type for them in the US, and that absence is worth taking seriously.
There is a hard ceiling that settles what the heat can’t be. Every one of these units plugs into a standard 115V, 15-amp outlet, capping draw at about 1,725 watts. Electric resistance heating converts electricity at a fixed 3,412 BTU per kilowatt-hour — a physical constant no product beats — so resistance heat from a normal wall plug tops out around 5,900 BTU, and realistically 4,300–5,100 BTU at the amperage these units actually pull. Any portable claiming meaningfully more heat than that on a household circuit must be a reverse-cycle heat pump.
De’Longhi claims nothing, so the test can’t confirm anything either way. The safe reading is that the HL models provide supplemental heat for taking the chill off a single room, not heat-pump heating you can plan a shoulder season around. If heating is genuinely part of the job, buy a unit that documents it: the Midea Duo’s own manual confirms heat-pump operation from 41°F, and our portable AC with heat guide ranks the units whose specs survive that scrutiny.
Where De’Longhi loses
Three structural gaps, none of them fatal, all of them worth knowing:
No dual-hose model. The entire Pinguino line is single-hose, which is where that 62 percent capacity retention in the table above comes from. A single-hose portable exhausts air it already paid to cool and puts the room under negative pressure, drawing hot outdoor air in through every gap. The Midea Duo’s hose-in-hose design is the current answer to that problem, and De’Longhi has no equivalent.
No inverter compressor. De’Longhi’s efficiency story is thermostat logic — Real Feel, Cool Surround, Eco mode — rather than variable-speed hardware. Inverter compressors run typically 20–35 percent more efficiently and noticeably quieter than fixed-speed ones by modulating instead of cycling on and off, which is why LG’s dual-inverter portables and Midea’s inverter units win on running cost.
No window units at all. De’Longhi does not sell a window air conditioner in the US — no slab units, no U-shaped saddle model, no mini-split. If your window is available and you just assumed portable was the category, read our window AC guide first, because a window unit is the more efficient machine in almost every case where you can install one.
The bottom line
Buy a De’Longhi Pinguino for the reason De’Longhi is actually good: thoughtful comfort control in a well-built, quiet package. The PAC EX390LVYN is the one to get, and its Cool Surround sensing remote is a legitimately unique feature — a thermostat that lives where you do. The PAC EX390LN is the same cooling class for less money, and the compact PAC EM375WRC is the bedroom pick.
Then do the one thing the box won’t do for you: ignore the 500 and 700 sq ft badges and size from the SACC number. De’Longhi publishes 8,700 BTU SACC against 14,000 BTU ASHRAE on the EL290HL, and at the DOE’s own 20-BTU-per-square-foot rule that’s a 435 sq ft machine wearing a 700 sq ft label. Size it right and you’ll like it. Size it from the badge and you’ll conclude De’Longhi makes weak air conditioners, when what it really makes is honestly-rated ones with optimistic marketing on the carton.
