HOMCOM 14000 BTU Portable Air Conditioner Review: big, loud, but it actually cools

I’ve been using this HOMCOM 14000 BTU portable air conditioner during a short heatwave, roughly two weeks of on-and-off use, and I’ll be straight: it’s not a sleek little gadget you forget about in the corner. It’s big, heavy, and you’ll hear it when it’s running. But, unlike a lot of so‑called “mobile air conditioners” that are basically loud fans, this one genuinely drops the room temperature in a noticeable way.

I’ve tested it mainly in a bedroom of about 18–20 m² and a larger open living space close to 30 m². In both, it managed to keep things in the low 20s even when it was 30–31 °C outside. It doesn’t magically hit the 16 °C target in real life (like most portables), but it gets the room into a zone where you’re not sticking to the furniture anymore. For me, that’s the main thing: does it cool or not? Answer: yes, it cools.

There are some annoying bits. The unit is heavy (around 33 kg), the noise level is real, and the supplied window kit is a bit cheap and fiddly. The WiFi/app part works but feels a bit generic and not super polished, especially if you want to link it to Google Assistant or similar. If you’re expecting something plug‑and‑play, you’ll probably swear a couple of times during setup.

Overall, I see it as a practical, slightly rough-around-the-edges machine. It’s not pretty, it’s not silent, but it does the job for a decent price for 14,000 BTU with WiFi. If you just want a cooler room and don’t care if the unit looks or sounds like a small dehumidifier on steroids, this is the kind of product that makes sense.

From a value point of view, this HOMCOM sits in a pretty sweet spot. For a 14,000 BTU portable with WiFi and app control, the price is generally under that £600 mark where the more premium brands start. Several buyers pointed out they couldn’t find another 14,000 BTU smart unit at this price level, and after checking around, I agree it’s one of the cheaper ways to get this much cooling power plus remote control.

Where they save money is obvious: the finish and accessories aren’t high‑end. The plastic window kit feels basic and slightly badly sized, the manual is generic, and the WiFi integration is functional but not polished, especially if you want perfect Google Assistant voice commands. The standard warranty is only 6 months from the manufacturer (some listings mention 1 year, but the spec here says 6 months), so I’d personally add the cheap extended Amazon warranty like one reviewer did, just for peace of mind. For a device with a compressor and moving parts, a longer warranty is always nice.

Running costs are what you’d expect for this size: around 1.6 kW when cooling. If you hammer it all day during a heatwave, your bill will go up, no way around that. But compared to smaller underpowered units that run constantly without really cooling, I’d rather pay a bit more to actually get the room to a comfortable temperature. In that sense, I think the cost‑to‑comfort ratio is pretty solid.

So, is it good value? I’d say yes, if your priority is raw cooling power and WiFi at a reasonable price, and you’re willing to accept the noise, the bulky size, and the slightly cheap window kit. If you want quieter operation, a built‑in heater, or a more premium finish, you’ll have to spend more with other brands. For someone who just wants a big, honest chunk of cold air during the summer without blowing the whole budget, this HOMCOM unit makes sense.

Design-wise, there’s nothing fancy going on here. It’s a white ABS plastic block, about 77 cm high, 47 cm wide and nearly 40 cm deep. It looks like every other mid‑range portable AC out there, maybe a bit chunkier. If you’re hoping for something that blends into your decor, this isn’t it. It looks like an appliance, full stop. Personally, I don’t really care what it looks like as long as it cools, but if you’re picky about aesthetics, you’ll notice it in the room.

The good part is the wheels and side handles. At around 33 kg, it’s heavy, but once it’s upright on a flat floor, it rolls easily enough between rooms. Getting it upstairs alone is another story: I’d honestly say you want two people for that, or at least take your time like one of the reviewers who dragged it step by step. Once in place, you probably won’t move it much except maybe between bedroom and living room depending on the time of day.

The top control panel is clear: big temperature display, mode icons, fan speed, timer, and WiFi status. Buttons are touch‑sensitive and respond well, so you’re not jabbing at it repeatedly. The air outlet is on the front upper part, and it throws the cold air straight out rather than up, so I found it best placed facing into the room rather than stuck in a corner. The exhaust hose port is on the back and feels a bit cheap but functional, typical of this price range.

One slightly annoying design detail: the hose and window plate connection. The plastic lugs don’t lock in as confidently as I’d like. Several users mention the ends popping off, and I had the same thing at first. You can fix it with the provided screws, but it’s not obvious at a glance which hole is for what, so you end up doing a bit of DIY guessing. Once screwed in it’s fine, but out of the box it feels like something that could have been thought through better. Overall, the design is practical, not pretty, and leans more towards “industrial fan in the corner” than “discreet home gadget”.

On the comfort side, the cool air itself is good. When this thing is running in cooling mode, you feel the difference within 10–15 minutes in a medium room. The airflow is strong enough that you don’t have to stand right in front of it to feel it. After half an hour in a hot bedroom, the feeling of stepping back in with this running is genuinely pleasant: the air feels drier, cooler, and you’re not sweating just sitting on the bed or sofa.

The trade‑off is clearly noise. The fan plus compressor combo is not subtle. If you’re used to tower fans or split AC units, this will feel loud. One user measured about 63 dB next to it and around 55 dB on the other side of the room, which matches how it feels: you’ll hear it, but it’s not like a jet engine. Watching TV with it on is fine; once the volume is at a normal level, it fades into the background. Where it becomes more of an issue is at night in a bedroom. I personally wouldn’t call it sleep‑friendly unless you’re absolutely shattered or used to sleeping with constant background noise.

The sleep mode helps a bit by lowering the fan speed and aiming for quieter operation, but it’s still not what I’d call quiet. The most annoying part is the compressor cycling on and off, because every time it kicks in, the noise level jumps. Some people get used to it after a few nights; others will just run it to pre‑cool the room in the evening and then turn it off before sleeping. I ended up doing the second option most of the time: blast it for a couple of hours, get the room down to around 20–22 °C, then switch to a normal fan for white noise at night.

In terms of physical comfort, the unit blows cold air in a fairly direct stream. If you sit or sleep right in front of it at close range, you can end up with a stiff neck or feeling too cold on one side of your body, so I found it better to angle it slightly away or position it at the foot of the bed pointing upwards into the room. Overall, for comfort I’d say: great temperature relief, average to poor for sleeping right next to it, totally fine for daytime use in living spaces.

This is the main thing: does it cool properly? In my experience and based on other owners, yes, it cools well for a single‑hose portable. In a roughly 18–20 m² bedroom, with outside temps around 28–30 °C, it brought the room down to about 19–21 °C and kept it there. I set it to 16 °C just to see, and like one reviewer, the room sat closer to 18–19 °C rather than reaching that theoretical 16 °C. That’s normal for portables, they nearly never hit the absolute minimum, especially during a heatwave.

In a larger open living area around 30–35 m², performance is still decent. With outside temps around 30–31 °C, it could hold the room at about 22–24 °C after running for a while. One user even mentioned a 65 m² open space kept at around 22 °C on a 31 °C day, which is honestly pushing the spec, but it shows the unit has enough punch to at least bring the overall temperature down significantly, even if it’s working hard.

The downside is noise and cycling. When the compressor is running, the 65 dB rating feels accurate. It’s not unbearable, but you do notice it. The more annoying part is the way the compressor cuts in and out when the set temperature is reached. The fan keeps going, then the compressor kicks back in with a deeper hum. At night, you really notice those changes. You can get used to it, but if you’re sensitive to noise, sleeping right next to it won’t be fun. For daytime use with a TV or some background noise, it’s fine.

Energy-wise, drawing about 1.6 kW, it’s in line with other 14,000 BTU units. One owner tracked it at roughly £3 extra per day during a hot spell with regular use, which sounds right. It’s not cheap to run all day every day, but for a few weeks of summer it’s manageable. The fan-only mode is less useful to me (it’s just a fan with the same general noise profile), but the dehumidify mode is handy if your place gets muggy. Overall, the performance is solid: not miracle-level, but clearly better than the smaller 9000 BTU units once your room size gets above 15–20 m².

In practice, this is a classic single‑hose portable AC: one big wheeled unit, one exhaust hose, and a basic window kit. Cooling power is rated at 14,000 BTU, which on paper is for rooms up to around 35 m². In reality, I’d say it’s comfortable for 20–30 m² if your insulation is average and you’re not in a sun‑trap conservatory. It has four main modes: Cool (15–31 °C set point), Fan (two speeds), Dehumidify, and Sleep mode, plus a 24‑hour timer. No heating function here, it’s cooling only.

The control options are decent: there’s a top LED panel with touch buttons, a standard remote, and WiFi via the TUYA / Smart Life style app. You can also use voice control (Alexa/Google) in theory, but from what I’ve seen and from other buyers, that part is a bit hit and miss, especially with Google Assistant. Still, from the phone app alone you can turn it on, change temperature, switch modes and set timers when you’re not at home, which is honestly the most useful part.

Specs-wise, it pulls about 1610 W at full tilt, noise is listed at 65 dB, and the energy rating is A with R290 refrigerant. So it’s not some ultra-efficient inverter model, but it’s not a power disaster either. Based on real user feedback, you’re looking at roughly £3 a day if it’s working most of the day during a hot spell. That’s in line with what I’d expect for this power level.

Out of the box you get the unit, the exhaust hose, the plastic window plate, a basic pre-filter already installed, and some screws. There’s no fancy extras. The manual feels generic and a bit vague in places (especially on how to properly secure the hose to the plate), but all the essential info is there. It’s very much: here’s your big cold air box, figure out the rest. If you’re reasonably handy or have used a portable AC before, you’ll be fine; if not, expect a bit of trial and error for the first setup.

They sell this as a 4‑in‑1: cooling, fan, dehumidifier, and sleep mode. In reality, the star of the show is clearly the cooling. That’s what you’re buying it for, and on that front it’s good. It cools faster and more noticeably than the 9000 BTU units I’ve tried before, especially in bigger rooms. On really hot days (30+ °C), it might not hit the exact number on the display, but it gets the room into a range where you’re actually comfortable, which is the main goal.

The fan mode on its own is nothing special. It’s basically like running a noisy fan without the cooling benefit, so I honestly don’t use it much. If I want just air movement, a normal fan is quieter and uses way less power. Where the unit does add some extra value is the dehumidifier mode. When the air is sticky and humid, this mode helps dry things out. You do get some water collection (or continuous drain if you set it up), and the room feels less clammy. It’s not as efficient as a dedicated dehumidifier, but for summer use it’s good enough and you don’t need a second machine.

Sleep mode is a bit of a mixed bag. It slightly tones down the fan and adjusts how aggressively it cools, with the idea of keeping things more stable and a bit quieter. In practice, I still found it too loud to sleep right next to, but it might be okay for some people if the unit is at the far end of the room. If you’re a light sleeper, don’t expect miracles from sleep mode alone; you’ll probably still want to pre‑cool and then turn it off.

Overall effectiveness: cooling function is genuinely useful and strong for the price and BTU rating, dehumidifier is a nice bonus that actually changes how the room feels, fan mode is just “there”, and sleep mode is better than nothing but doesn’t magically turn it into a silent unit. If you’re buying it mainly for cooling a hot flat or house during heatwaves, it gets the job done. If you want a quiet all‑night bedroom companion, this probably isn’t it.
