## How many tons of AC do I need per square foot?

Understand here that the standard practice among

**HVAC**contractors sizing air conditioners for new homes is to use a rule of thumb. It's often in the neighborhood of 1**ton of air conditioning**capacity for each 600**square feet**of conditioned floor area, usually abbreviated 600 sf/**ton**.8

## How many square feet are in a 12 by 12 room?

The formula for figuring this out is pretty straightforward, all you have to do is multiple the length of the room by the width. So if your room is

**10 feet**by 12 feet, 10 x 12 =**120 square feet**.9

## How many square feet does a 8000 BTU air conditioner cool?

1. Cooling Capacity

Area To Be Cooled (Sq. Ft.) | Capacity Needed (BTUs Per Hour) |
---|---|

300 to 350 sq. ft. | 8,000 BTUs |

350 to 400 sq. ft. | 9,000 BTUs |

400 to 450 sq. ft. | 10,000 BTUs |

450 to 550 sq. ft. | 12,000 BTUs |

## How many amps does a 24000 BTU air conditioner use?

A typical 2-ton central air unit that puts out 24,000 BTUs will draw between 15 and

**20 amps**.11

## What is a SEER rating for air conditioners?

**SEER**stands for Seasonal Energy Efficiency Ratio. The

**SEER**measures

**air conditioning**and heat pump cooling efficiency, which is calculated by the cooling output for a typical cooling season divided by the total electric energy input during the same time frame. A higher

**SEER**rating means greater energy efficiency.

## What is meant by Btu of air conditioner?

The right

**air conditioner**helps you cool a room efficiently. You also need to know the**air conditioner's BTU**(British Thermal Unit) rating, which indicates the amount of heat it can remove from a room. A higher number means more cooling power for a larger room.13

## How much does it cost to replace a central air conditioning unit?

Homeowners can pay between

**$500**and**$4,000**for central air conditioning. The final cost will depend on the unit, additional installation items such as ductwork and the professional's installation rates. Here are some additional factors that will determine the kind of system you will need, as well as its price.14

## How do you measure a room?

To do so, use a tape

**measure**to determine the**room's**length and width. Then multiply the length by the width to get your square footage. For instance, if the**room**is 12 feet wide and 12 feet long, you will need enough flooring for 144 square feet (12×12=144).15

## How many Btu are in a ton?

A refrigeration ton is approximately equivalent to

**12,000 BTU**/h or 3.5 kW. Air-conditioning and refrigeration equipment capacity in the U.S. is often specified in "tons" (of refrigeration). Many manufacturers also specify capacity in BTU/h, especially when specifying the performance of smaller equipment.16

## How many BTU do I need per square foot?

Multiply the total square footage to be heated by the heating factor. If you live in a 2,500 square foot home and a climate zone with a heating factor of

**40 BTUs**per square foot, you need a furnace with an output of**100,000 BTUs**per hour.17

## What size furnace do I need for a 1000 square foot home?

A basic rule of thumb is that it takes 30 BTUs for every

**1,000 square feet**. At the most basic level, if you**have**a**1,000 square foot house**, you'll look for a**furnace**that has 30,000 BTU output.18

## What is the SEER rating mean?

**SEER**stands for Seasonal Energy Efficiency Ratio. It's a measurement of an air conditioner's cooling capacity to power input, or simply, the ratio of cooling produced (in BTUs) divided by the amount of electricity used (in watts). The higher the

**SEER rating means**the greater the unit's efficiency.

## How many square feet is my room?

Assume you have a rectangular area such as a

**room**and, for example, you want to calculate the**square**footage area for flooring or carpet. The way to calculate a rectangular area is by measuring the length and width of**your**area then multiplying those two numbers together to get the area in**feet**squared (ft^{2}).
