This estimate is most accurate in new construction or newer homes that have proper insulation.
1 500 x 30 45 000.
To figure out what size air conditioner you require you first need to determine the amount of btus you require.
There are 12 000 btu s per ton.
So for instance a 1 500 square foot home would look something like this.
If your btu requirement is between sizes simply go with the bigger unit.
In general you should have approximately 1 ton of ac capacity to cool 600 sq ft.
But your hvac dealer only has air conditioners that handle 24 000 or 30 000 btus.
Having a little extra power isn t bad.
Residential central air conditioners come in a range of sizes from 1 5 ton to 5 ton models.
The system capacity will be coded into the model number of the outdoor unit.
Both offer a measurement of an air conditioner s cooling ability over an hour s time.
For example the manual j calculation may say you need 25 000 btus for cooling.
One ton of cooling capacity is equal to 12 000 btuh.
This is close to the 400 square feet per ton sizing of the hvac industry in chicago and orlando but you will notice the variance due to us adding a kitchen and windows.
Assuming one ton of cooling capacity can cool 400 square feet of your home you ll need about 5 0 tons of air conditioning capacity.
Instead of subtracting 1 0 instead subtract zero to get the appropriate ac size for hot and arid climates.
For homes that range 3000 sq.

An air conditioner s cooling capacity is expressed in btuh british thermal units per hour or tons often referred to as tonnage.
The number 24 in the model number indicates the unit is 24 000 btu s divided by 12 000 btu s per ton equals 2 tons.
Btus stand for british thermal units and refer to the amount of energy your air conditioner is using per hour.
