Yep I did that to mine, HUGE difference. In fact it still gets rather warm as there's a piece that's not insulated well enough because of how it bends. I can bring the room down to 22C or so on a hot day. The best is when I get back from outside all sweaty and feeling really crappy, I go in there, close the door and let it blow right on me. Instant comfort.

I know it's hard to resist but that is surely a good way to catch a sniffle! 😉

Well a poorly maintained condensate pan can harbor nasties but my point was that cold air blowing on a sweaty person is bad. Just like one should not walk outdoors in colder months right after showering with wet hair...

ductless? then how does the hot air get vented from the room?

It's a split system.

Indoors there is a fan+coil which connects to an outdoor unit via piping (liquid and suction lines). This outdoor unit has the compressor, fan, and coil. Some of these also are heat pumps so the cycle is reversible and can provide heat in cooler months. They are very quiet as the indoor fan can be designed to produce very little noise. Efficiency can also be very high (over 21 SEER).

Generally pro installation is recommended but those that are handy can do it. They come with the lines pre-charged so there is no worry of handling refrigerants or brazing copper tubing, etc. Just mount indoor unit, set outdoor unit on pad, bore holes in wall, connect electrical power to both units, pass precharged lines through wall(s) and connect following detailed instructions. Some may want to have an electrician install the power feed if they are not familiar with local wiring codes and methods.

These units work well and will deal with hot areas where equipment is mounted nicely.
 
I have the mitsubishi ductless as recommended by rubycon. These things are awesome.

I used to have a 20,000 btu window unit. I only ran it from 11PM -7AM - I can't sleep in my own sweat. It still does not cool the room well but that's what I had. During summer, just running that 1 room cost around 250/month

After i switched to the ductless units, I run ac in 2 room from 6pm till 8AM and my electrical bill was around 189/month.

Granted they're from 2 different years and I have no way to compare the temperature between the years that I had a window unit and years that I'm using the ductless. But running the units longer and probably hotter periods of summer is costing me less.

They're also quiet as hell, you barely notice that compressor humming and kicking in and out.

Of course i pay through the nose but they are so worth it when its hot as hell outside.
 
An 8000 BTU unit should be sufficient for that small of a room, but be warned it is will be loud. Get a dual-hose system.

FYI I use a 9000 BTU unit for a 14x20 basement room in the worst of summer heat waves, but I am happy with 75 degree room temperatures. But it is not sun facing, so you will need something 25% stronger than what a BTU calculator says.

oh.. so it's like a mini central air unit

gee.. that sounds ALOT more than a portable a/c unit

Mini split is essentially like central air, but without the ducts. It's a permanently installed system. They are good, but for the money they cost (couple grand) it makes more sense to pay double and get a full central air system. Though if a single room needs to be cooled more than another, mini split is a good alternative to noisy portable/window units.

My particular unit actually evaporates the water out, so there's no drain pan. Some have a drain pan which is quite a pain to use, some the pan does not even come out and you have to wheel the unit over and lift it into the tub and let it drain. Was reading reviews online on some before I bought mine.

Never gotten sick from standing in front of it though, it's a 1 ton unit for a room that's just under 100 square feet, so I'm pretty sure any bacteria that exists are frozen to death in there. I probably should clean it out at the start of each season though. If there's any standing water anywhere it can grow legionaries disease and stuff.

Modern systems drip the water on the coils. It improves the efficiency of the system by using evaporative cooling. I don't think portable units (can) do this. So they're less energy efficient.

Mine actually does, it's one of the "extra features" it has, but yeah most of them don't, and have the drain pan. Some have a hose that goes outside and has a pump.

Mind you this was a very expensive unit too, think I paid like $800 for it several years ago. Will keep the room to 21-22 nicely though. It's just so loud. 😱 I also went overkill and oversized to the highest I could find. This could technically do like half the house if I was to duct it to the rooms.

but if i buy a full central air system for twice the $ of a mini-split, wont i also have to spend $$$ for duct work?
 
IMO, don't get a portable. I would mount one in the wall before I bought a portable. They just don't do a good job. Based on experience.

Oh with no duct work then yeah makes more sense to go with mini split. Retro fitting duct work can be a challenge especially if the basement is drywalled. If it's open, it's doable but still would add to the cost.

Yeah if I was to do it over again think I would have gotten a window unit and just made it fit through the wall and install it in a permanent way. All my windows are crank windows so it makes window units hard to setup. They actually make 2 ton window units too, they require a 240v outlet. They also make through the wall units that are designed for going through a wall, guessing they're probably better insulated and longer.
 
I was in the same situation years ago, ended up buying one online that had good BTU rating, remote, and other bells and whistles. I was unimpressed with the documentation when installing it, and had to really screw with the window adapter and tubing to make it work.

It worked great installed in our bedroom for almost 2 summers, kept us cool so we could sleep without opening windows (and letting in biting things small enough to fit through the screen). When it started to suck I thought, no worries, just needs a coolant recharge. Unfortunately for me I had purchased a product from a shitty company. Unit was sealed, i.e, no recharging. You only find that out when you call them upset; sleazy bitches made no mention of it in product descriptions, on the box, or in the manual. So, beware!

Ended up replacing it with an LG unit from Lowes. It was rated at lower BTUs than the POS that came before it yet did a much better job, and at a lower wattage. Cheaper too. I remember being impressed at how little water it produced, apparently LGs "Evaporative Technology" is not a gimmick. With the first unit I was emptying my homemade reservoir every day. With the LG it was once, maybe twice a week.


So my advice is to check out LG.

Better than having a HOA that pretty much told me to go f*ck myself :|

Got a DeLonghi for ~$200AR at Sam's last summer (single-duct type). No leaks and works extremely well in supplementing my central AC (small condenser, can barely keep the apartment at 85-90 during the TX summers).

[FONT=&quot]The best small portable air conditioner will have an energy star rating that reduce the electricity bills. Check the rating before buying the cooling unit as this type of air conditioner is extremely energy-efficient. And also these are environmentally friendly. [/FONT]
