TCL H12T9E1-A Smart Through-The-Wall Air Conditioner, Fan & Dehumidifier: 12,000 BTU cooling capacity
When the heat's on, the TCL 12,000 BTU Through-the-Wall Air Conditioner doesn't just cool your space—it owns it. Perfect for areas up to 550 sq. ft., this beast of a unit packs a punch with its 12,000 BTU capacity. And hey, it's not just about cooling; flip it to fan mode when you're feeling breezy, or let it dehumidify to take the swamp out of your swampy summer days.
Now, let's talk smarts. Control it from your couch with the TCL Home App, or just yell at Alexa or Google Assistant if you're feeling lazy (we've all been there). It's got tricks up its sleeve too, like Sleep and Eco modes that save energy while keeping you comfy. Plus, the washable filter means you're not just breathing in last year's dust bunnies—clean air and a happy AC, what's not to love?
Setting it up? Easier than assembling flat-pack furniture (and way less frustrating). The LED display and remote are straightforward, so you won't need a manual the size of a novel. Just a heads-up: the sleeve's sold separately, so make sure your wall's ready for a 26”x20”x15.57" hole. Yeah, it's specific, but hey, precision is key.

Smart Through-The-Wall Air Conditioner, Fan & Dehumidifier
Baptiste L.
Lyon
May 16, 2025
so, what's the deal with this thing? well, as an office worker in lyon, i needed something to handle the summer heat without breaking the bank, and this unit does the job. i've had it for a couple of months now, and it's been reliable. cooling is strong—it chills my space fast, and the dehumidifier helps on muggy days. controlling it remotely is a game-changer; i can adjust it from my couch or even while i'm out, which is super convenient. the fan mode is nice for a breeze without the chill. but, honestly, the separate sleeve purchase was annoying, and the installation required careful measuring. it's not perfect, but for the price, it's a solid choice. i'd recommend it if you're okay with a bit of extra setup work.
- Pros: frankly pretty good at cooling my room quickly, and i quite like that i can control it with my phone or just by talking to my assistant. the fan and dehumidifier options are handy for different weather, and the filter is easy to clean, which keeps the air fresh. setup was straightforward, and the display and remote are simple to use without needing a manual.
- Cons: could be wrong, but the sleeve isn't included, so i had to buy that separately, which was a bit of a hassle. it's quite specific in size, so making the hole in the wall had to be precise. also, while it works well, it might not be the quietest when running on high, and i wish it had more energy-saving options beyond the basic ones.
