My LG air conditioner keeps beeping for no reason. It runs fine but it keeps beeping. I know it covers 1500 square feet but that's about all I know

• Hi Tony: Don't know what this has to do with air conditioners but .......
• Square footage is the mathematical result when you multiply length by width.
• Since you're trying to find square feet. the dimensions that you are using must be in feet.
• Length (feet plus (inches divided by 12))
• times
• Width (feet plus (inches divided by 12))
• equals
• square Feet.
• Any questions or numbers for your project? Just reply as a comment to this post.
• Cheers

Hi Sharee:
The square footage is 14 times 70 equals 980 square feet.
That would be the Floor Area.
Air conditioners sometimes need to know the building volume so if you have 8 ft ceilings you would multiple 980 by 8 to get 7,840 CUBIC FEET.
Air exchange is typically are rated at cubic feet per minute and required as "specified Air Changes per Hour.
An example for your trailer would be 1/2 air change per hour required per building code. 7,840 times 1/2 equals 3920 cubic feet per hour. Divide that by 60 to get 65 cubic feet per minute.
That would be the minimum air change capacity for your air conditioner if it was also providing required ventilation.

Read size of air conditioner you need , each ton of air conditioning will keep cool 400 square.so higher ton yo pick you feel cool.please read below square feet to ton chart.
1 ton on 400 sq. ft.
2 ton on 800 sq. ft.
3 ton on 2000 sq. ft.
5 ton on 2570 sq. ft.

12000 btus = 1 Ton. A simple ballpark method is 600 to 800 Square feet per ton of cooling. Therefore using this simple method I would say that a 2 or 2.5 ton would do just fine.

With that said the best way to determine the actual size is to perform a heat load calculation on the home. The process can be pretty overwhelming if you don't do it every day. You could call a local HVAC company to perform the calculations for you or you can purchase software online for a couple of hundred dollars and do it yourself.

Either way you choose remember that a properly sized air conditioner offers less hot and cold spots in the home and keep the utility bills down.

If the system is actually doing everything it can, which I do occasionally run into, then it's time to start looking at other factors like the heat loads. Number one problem I run into is either attic insulation or attic ventilation. One thing that really sticks out in your post though is the square footage and tonnage. Now, to be honest, what the square footage is from the home owner to actual living space always varies. Home owners always get the square footage like a realtor, but includes the garage and other unconditioned rooms. What your looking for is the square footage of only the rooms that have a vent. It is 400cfm per ton, 1 cfm per square foot. So if you have a 2.5 ton system, it is capable of doing 1000 square feet of living space. You said 1500 square feet, which would need a 3.5 to 4 ton system. Hope this helps and gets you to cooler days!

The air is cool but doesn't seem cold enough If the air doesn't seem cool enough it is necessary to use a thermometer to check the difference in temperature between the air going into the unit and the air being blown into the room. Ideally, the temperature difference should be more than 15 degrees. For example, if the temperature going into the air conditioner is 80 degrees, the temperature coming out of the unit should be at least 65 degrees or less. If the difference is 15 degrees or more there is probably no cause for concern. If the temperature difference is less than 15 degrees you should check the following:

• Air damper

Check to make sure the air damper is closed. If it's open, it will bring in outside air and reduce the efficiency of the unit.

• Back cover

During the winter season many people cover their air conditioners to protect the unit from the weather. In the spring or summer they will sometimes forget to remove the cover. If your unit has a cover on the outside portion of the air conditioner remove the cover first.

• Condensing coils

The condensing coils will always be on the "warm" side of the air conditioner. That is, on the side that faces outside of the room to be cooled. Air is drawn into the back of the air conditioner on the sides through vent slots and is blown directly out through the condenser coils. If the coils get clogged with lint, dust and dirt the cooling system cannot provide the cooling necessary. To clean the coils it will be necessary to remove the entire cover of the air conditioner or pull it out of the wall to gain access to the coils. They can be cleaned by blowing compressed air at them or by using a soft bristle brush to wipe the dirt off. It is important to also clean any dirt or lint build-up in the bottom of the air conditioner so the condense water will be picked up by the condensing fan slinger properly.

It could also mean that you are trying to cool too big an area for the size of the unit.
AREA TO BE COOLED / CAPACITY (BTU/HR)

100 to 150 square feet = 5,000
150 to 250 square feet = 6,000
250 to 300 square feet = 7,000
300 to 350 square feet = 8,000
350 to 400 square feet = 9,000
400 to 450 square feet = 10,000
450 to 550 square feet = 12,000
550 to 700 square feet = 14,000
700 to 1000 square feet = 18,000

Your bryant 56cj024-d is a 2 ton unit, which cools an even 1000 square feet of space. you need a 2 1/2 ton unit, which cools 1500 square feet.

Hello, I can assist you.

If the unit is supposed to turn off and it doesn't, it will be necessary to check several things.

• First, is the unit cooling properly? See the section entitled "The air is cool but doesn't seem cold enough."
  
  
• Next, is the temperature of the room adequately cool? If the room temperature is cold enough try setting the thermostat to a higher temperature. If the unit then seems to work properly leave the thermostat set to the higher temperature.
  
  
• If the unit is cooling properly when it is turned on and the room is not cool enough the problem is probably that the unit is trying to cool an area that is too large for its capacity. Use the following chart to find the appropriate size air conditioner to use:
  
  

AREA TO BE COOLED / CAPACITY (BTU/HR)

100 to 150 square feet = 5,000

150 to 250 square feet = 6,000

250 to 300 square feet = 7,000

300 to 350 square feet = 8,000

350 to 400 square feet = 9,000

400 to 450 square feet = 10,000

450 to 550 square feet = 12,000

550 to 700 square feet = 14,000

700 to 1000 square feet = 18,000

If the room is heavily shaded, reduce needed capacity by 10%

If the room receives a lot of direct sun, increase needed capacity by 10%

Add 600 Btu/Hr for each person in the room if there are more than two people

If the unit is for a kitchen, increase the capacity by 4,000-6,000 Btu/Hr.

If the room size is too big for the air conditioner you have two possible choices. Either decrease the room size by shutting some doors or partitioning off an area of the room. Or, increase the BTU of the air conditioner for that room by installing a different air conditioner with a higher BTU rating.

Th info I keep finding is 14,7000 which is just over 1 ton of cooling. Each ton is 12,000 Btu. Probably designed to cool about 400-500 square feet.

What size unit do I need for my room? Use the following chart to find the appropriate size air conditioner to use:

AREA TO BE COOLED / CAPACITY (BTU/HR)

100 to 150 square feet = 5,000

150 to 250 square feet = 6,000

250 to 300 square feet = 7,000

300 to 350 square feet = 8,000

350 to 400 square feet = 9,000

400 to 450 square feet = 10,000

450 to 550 square feet = 12,000

550 to 700 square feet = 14,000

700 to 1000 square feet = 18,000

If the room is heavily shaded, reduce needed capacity by 10%

If the room receives a lot of direct sun, increase needed capacity by 10%

Add 600 Btu/Hr for each person in the room if there are more than two people

If the unit is for a kitchen, increase the capacity by 4,000-6,000 Btu/Hr.
