What size air conditioner do you need?

Answer 1

The only way to determine the proper size air conditioner required is to have a load calculation performed. This takes into account the construction features of the home as well as its' location.

that is the only for sure way to get it dead on, a trick i use a lot is 700 sq per ton on a older house 900 a ton on a newer house

Answer 2

One ton is equal to 12,000 btu, look for a 2 digit # in the model that is divisible by 6 (for 1/2 ton increments). That # is usually the units capacity in 1000`s of btu. So a model # with a 30 in it would be 2.5 tons. (30,000 divided by 12,000= 2.5) a 48 would be 4 tons and so on, usually the range for a home central unit is limited to between 1.5 and 5 tons or 18 to 60 in increments of 6 the model#.

Answer 3

Ideally you should not use an air-conditioner at all. Air-conditioners are a large consumer of electricity and and push "peak load" in electricity networks driving the demand for more electricity generation.

A well designed "passive solar" house should not require the use of air-conditioners for maintaining comfortable internal summer temperatures

Answer 4

The size of air conditioner you need depends on the square footage of the space you want to cool. A general guideline is to calculate the square footage of the area and then match it with the appropriate BTU (British Thermal Units) rating for the air conditioner to ensure efficient cooling. It's best to consult with a professional HVAC technician to determine the right size for your specific needs.

Answer 5

It Takes 12,000 BTU To Equal One Ton If You Have An 18,000 BTU You Have 1 & 1/2 Ton

Answer 6

It depends on many factors, including the size of the room, how insulated it is, and what sources of heat gain are present.
