Hitachi is a good brand, I wouldn't be afraid of it.

As to the size, it seems a little 'oversized' for the room you're talking about.

24x12 = 288 sq ft. As a general rule you need 12000 btu for every 600 sq ft.

I'm thinking between 6000 -10000 btu ought to be big enough.

Lots of things go into sizing, and the size of the room is important - but the 'heat load,' needs to be considered too. For example - will there be a lot of people in this room, or is there a lot of windows, is there electrical equipment in this room that will be putting off heat, and how well is it insulated? So you need to consider all of these things when deciding what size unit to buy.

For example - if this room is a bedroom and used primarily for sleeping - I wouldn't be afraid to put a 6000 btu unit in it - but if it was going to be used as a place with tv's, computers and other electrical equipment I might want to put a 10000 btu (or larger) in it.

Good Luck!



Generally speaking, it sounds like 18000 btu is too much AC here, and there's no reason to spend more money than you need to and you can 'oversize' just as easy as you can 'undersize' when it comes to Air Condtioning.

My model is AEV05KB and recently I see water on the cooling pipes sometimes it drips and sometimes it forms snowlike formations and also if I put the cover on the snow completely coveres the parts inside...


It sounds like the unit is too small for the area being cooled. You should figure the square footage of the area and use this th figure what you need.

Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} Using the square footage and the chart below, determine the correct cooling capacity. Cooling capacity is measured in British thermal units (BTUs) per hour.Area To Be Cooled (square feet) Capacity Needed (BTUs per hour)
100 up to 150 5,000
150 up to 250 6,000
250 up to 300 7,000
300 up to 350 8,000
350 up to 400 9,000
400 up to 450 10,000
450 up to 550 12,000
550 up to 700 14,000
700 up to 1,000 18,000
1,000 up to 1,200 21,000
1,200 up to 1,400 23,000
1,400 up to 1,500 24,000
1,500 up to 2,000 30,000
2,000 up to 2,500 34,000


Make any adjustments for the following circumstances:
If the room is heavily shaded, reduce capacity by 10 percent.
If the room is very sunny, increase capacity by 10 percent.
If more than two people regularly occupy the room, add 600 BTUs for each additional person.
If the unit is used in a kitchen, increase capacity by 4,000 BTUs.
Consider where you install the unit. If you are mounting an air conditioner near the corner of a room, look for a unit that can send the airflow in the right direction.

AC was cooling fine. Now, won't cool room even though cool air comes out. Exhaust hose is extremely hot.


Check filter, if you have a 5000BTU unit (small) and it is extremely hot, then it wont work great for a big room. BTU is the rate of what the AC will put out. 5000 BTU is good for a small single room. 10,000 will cool a bigger room and 18,000 btu is meant to cool a home.

Air conditioner equipment power in the U.S. is often described in terms of "tons of refrigeration." A "ton of refrigeration" is defined as the cooling power of one short ton (2000 pounds or 907 kilograms) of ice melting in a 24-hour period. This is equal to 12,000 BTU per hour, or 3517 watts.[13] Residential central air systems are usually from 1 to 5 tons (3 to 20 kilowatts (kW)) in capacity. To determine the correct size keep in mind that 12,000 BTU's equals 1-ton. Use the table below to determine the size AC that you need. Hope this helps. Area To Be Cooled (square feet) Capacity Needed (BTUs per hour) 100 to 150 5,000 150 to 250 6,000 250 to 300 7,000 300 to 350 8,000 350 to 400 9,000 400 to 450 10,000 450 to 550 12,000 550 to 700 14,000 700 to 1,000 18,000 1,000 to 1,200 21,000 1,200 to 1,400 23,000 1,400 to 1,500 24,000 1,500 to 2,000 30,000 2,000 to 2,500 34,000

Just put in a new ac unit and replaced a old one. old unit was 18000 btu and the new one is on 12,000 btu I used the same power outlet but the new ac unit starts up but then shuts down and seems like it is...


The 18,000 btu A/C is 230 volts, are you sure the 12,000 btu unit is 230 volts most are 120 volts.
Usually 12,000 btu is the biggest 120 volt A/C you can buy.

Window or wall mount


The differance between a window and wall mounted A/C is the mounting system.
Window units are usually smaller BTU systems they set in the window, so you do not have to cut a hole in the wall to install it.
For a bedroom say 10 x 10 you can use @ 5000 btu it plugs into a standard 120 volt electric outlet. If the room is bigger then go bigger say @ 6000 btu or so. Take your room dementions with you when shopping for a unit. sometimes they have sizing on the side of the unit box.
Wall units are usually larger units. Like whole house 18,000 btu
they slide in and out of the case and use a 240 volt seperate circuit.
Best place to shop for A/C's are Home Depot, Lowes, Sams Club, B.J.'s, and Cosco they buy in large volumeusually give a Good deal I've seen 5000 btu units as low as $89.00
Just don't drop the unit out the window when installing it
From the second floor it will void your warranty. LOL
Good Luck Phil
