Quick Answer: The best currently-available Honeywell air conditioner in 2026 is the MO08CESWK6 (9,000 BTU ASHRAE / 6,100 BTU SACC compact), covering up to 400 sq ft and priced roughly $370-465 depending on retailer. The classic-series MN10CESWW this guide previously recommended as best overall is now confirmed discontinued directly on Honeywell’s own store — along with its would-be successors, the HL10CESWW and HL10CESWK, which are discontinued too. Want app control instead, the HF0CESVWK6 10,000 BTU Smart WiFi model adds Alexa voice control at $589.95 list. The fact most shoppers don’t realize going in: Honeywell doesn’t build these units itself — the brand is licensed to JMATEK Limited, a Hong Kong home-comfort manufacturer, the same kind of licensing arrangement Toshiba uses with Midea for its own AC line.
Last updated 2026-08-21: confirmed directly on honeywellstore.com that the MN10CESWW (“best overall” in a prior version of this guide) is discontinued, along with the HL10CESWW and HL10CESWK that looked like its successors — Honeywell’s classic 10,000 BTU single-hose tier has effectively been wound down. The MO08CESWK6 compact and HF0CESVWK6 Smart WiFi models are still current, though both show as out-of-stock directly on Honeywell’s own store (Walmart and Best Buy carry the MO08CESWK6; the HF0CESVWK6 has been seasonally hard to find everywhere in-stock this summer).
Honeywell’s name carries real trust — it’s a 100-plus-year-old industrial and aerospace giant — but that reputation doesn’t extend to in-house engineering on the portable AC aisle. Here’s what’s actually behind the Honeywell nameplate, how the current lineup breaks down, and which classic-series models have quietly disappeared.
Honeywell’s current lineup, decoded
| Model | BTU | Series | Room size | Price |
|---|---|---|---|---|
| MO08CESWK6 | 9,000 (ASHRAE) / 6,100 (DOE/SACC) | Compact | 400 sq ft | $370-465 |
| MN10CESWW | 10,000 | Classic — discontinued | 350-450 sq ft | N/A |
| HF0CESVWK6 | 10,000 (ASHRAE) / ~6,500 (SACC) | Smart WiFi | 350-450 sq ft | $589.95 |
| MN14CHCSWW | 14,000 | Classic, heat pump | 450-550 sq ft (cool) / up to 500 sq ft (heat) | ~$670 |
The classic MN-series was Honeywell’s mainstream single-hose lineup, sized 10,000-14,000 BTU, with a dehumidifier mode standard and an optional heat-pump variant (the MN14CHCS) that adds cooling and heating in one unit — but the 10,000 BTU entry, the MN10CESWW, is now confirmed discontinued, along with the HL10CESWW and HL10CESWK models that appeared to be its direct successors (also discontinued, per Honeywell’s own store). The compact MO-series remains current and drops to a smaller footprint for a single bedroom or office, at 9,000 BTU on the ASHRAE rating (6,100 BTU under the newer, stricter DOE/SACC standard, which is normal for the category, not a Honeywell-specific issue). The HF-series layers Smart WiFi and Amazon Alexa control on top of similar hardware, at a price premium over a non-connected model.
Who’s actually behind the Honeywell name
| Fact | Source |
|---|---|
| JMATEK Limited, a Hong Kong-based company founded in 2007, is the exclusive licensee of the Honeywell brand for Air Comfort products — evaporative coolers, portable air conditioners, and dehumidifiers — using the Honeywell trademark under license from Honeywell International Inc. | JMATEK company profile |
| The MO08CESWK6 currently ranges from about $370 (Appliance Guys) to $465 (Honeywell Store list price) across retailers | Cross-checked Honeywell Store, Walmart, Appliance Guys listings |
| The MN10CESWW ("best overall" in an earlier version of this guide) is confirmed discontinued directly on honeywellstore.com, as are the HL10CESWW and HL10CESWK models that looked like its successor | Honeywell Store product-page status (checked directly, 2026-08-21) |
This is worth knowing before you buy: like several other legacy brand names in this category, “Honeywell” on a portable AC box means you’re buying a licensed product, not something engineered in-house by the industrial giant. JMATEK has run this license long enough to build a genuinely wide MN/MO/HF catalog, but the arrangement also means Honeywell’s own corporate site and support infrastructure aren’t the ones actually standing behind the unit day to day — check honeywellstore.com or honeywellaircomfort.com (JMATEK’s own storefronts) rather than honeywell.com for support and warranty questions. And because pricing on these licensed lines swings unusually wide across retailers, treat an unusually low or high listing as a reason to double-check the seller, not a reason to buy immediately.

1. Honeywell MO08CESWK6 9,000 BTU — Best Overall (Currently Available)
Honeywell MO08CESWK6 (9,000 BTU ASHRAE / 6,100 BTU SACC)
- Compact-series cabinet with dehumidifier and fan modes, full remote control, and a washable air filter — the closest current equivalent to the now-discontinued MN10CESWW.
- Rated 9,000 BTU ASHRAE / 6,100 BTU SACC, covering up to 400 sq ft — a notch smaller than the MN10CESWW's old 450 sq ft claim, but the honest, current pick in this tier.
- No WiFi at this tier — for app/voice control, step up to the HF-series below.
Don’t sweat the heat wave — Amazon Prime delivers a portable AC like this in two days, and you can try it free for 30 days.
The MO08CESWK6 is now the default Honeywell recommendation simply because its former mainstream sibling, the MN10CESWW, is gone — confirmed discontinued directly on Honeywell’s own store, along with the HL10CESWW and HL10CESWK models that looked like natural successors. The dehumidifier mode is standard rather than an add-on, which matters if you’re in a humid climate and don’t want a separate unit. For how it stacks up against the site’s other compact portables, see our best portable AC for an apartment guide.
2. What happened to the MN10CESWW (and its HL-series successors)
Honeywell MN10CESWW (10,000 BTU) — Discontinued
- Confirmed discontinued directly on honeywellstore.com, where the product page now reads "This item has been discontinued."
- The HL10CESWW and HL10CESWK — same 10,000 BTU ASHRAE spec, same dehumidifier and remote features, and the models that looked like the MN10CESWW's direct replacement — are also confirmed discontinued on Honeywell's own store.
- If you already own an MN10CESWW, our portable AC filter replacement guide covers the washable mesh filter it uses, which is still the same maintenance part regardless of the model being discontinued.
For how the MO08CESWK6’s compact 400 sq ft footprint compares against other bedroom-sized portables, see our best portable AC for bedroom guide.
3. Honeywell HF0CESVWK6 10,000 BTU — Best Smart/WiFi Pick
Honeywell HF0CESVWK6 (10,000 BTU ASHRAE / ~6,500 SACC)
- Smart WiFi app control plus Amazon Alexa voice support — power on, change temperature, and adjust fan speed remotely.
- Same 10,000 BTU ASHRAE class the discontinued MN10CESWW used to occupy, at a premium for the added connectivity.
- A larger sibling, the 13,000 BTU HF2CESVWK8, has been discontinued by the manufacturer — confirm current availability before assuming a bigger HF-series unit is still in production.
Honeywell’s WiFi tier is a straightforward add-on to the same MN-class hardware rather than a separate engineering effort, so the case for paying the premium comes down to whether you actually want app/voice control. If you’d rather have that feature on a window unit instead, our best window air conditioner guide covers several smart-enabled options.
How to choose your Honeywell
- Want the mainstream, dehumidifier-equipped pick? The MO08CESWK6 9K — the safest current default at $370-465, now that the MN10CESWW is discontinued.
- Looking specifically for the MN10CESWW or an HL-series model? All three are discontinued — the MO08CESWK6 above is the closest currently-buyable equivalent.
- Want app/voice control? The HF0CESVWK6 adds WiFi and Alexa at a premium over the equivalent non-connected model.
- Need heating too? The MN14CHCSWW 14K cools up to 550 sq ft and heats up to 500 sq ft in one unit.
- Care who actually built it? JMATEK Limited, a Hong Kong appliance company, licenses the Honeywell name — the same kind of arrangement Toshiba uses with Midea, covered in our Toshiba air conditioner roundup, or see our best Arctic King air conditioner guide for Midea’s own budget house brand.
The bottom line
The Honeywell MO08CESWK6 is the best Honeywell air conditioner you can actually buy new in 2026 — its longtime mainstream sibling, the MN10CESWW, along with the HL10CESWW and HL10CESWK that appeared to replace it, are all confirmed discontinued directly on Honeywell’s own store. The bigger takeaway for shoppers: Honeywell doesn’t design or build these units itself, JMATEK Limited does under a brand license, which is worth knowing when you’re deciding whether Honeywell support channels or JMATEK’s own storefronts are the right place to go for warranty questions — and worth remembering that Honeywell’s own store showing an item “out of stock” or “discontinued” doesn’t always mean it’s gone everywhere, so cross-check Walmart and Best Buy before writing off a model.
