What size air conditioner or furnace do i need for my home.
Ton ac unit per square foot.
This is done by calculating your square footage.
If you need a unit that has more than 5 ton cooling capacity then it is likely you will need multiple ac units.
A ton is a measure of an air conditioner s ability to cool.
Ac calculator uses your house size square feet climate zone efficiency and equipment type standard central air vs central heat pump to show you exactly what size central air unit you need.
So now you are likely asking what is a btu.
If you have a one ton ac unit it means it has the ability to cool 12 000 btus an hour.
We get this question a lot and it s an important one.
The system capacity will be coded into the model number of the outdoor unit.
One ton is the ability of your air conditioner to cool 12 000 btus british thermal unit in an hour.
Likewise a 2 ton central air conditioner is able to cool 24 000 btus per hour.
If your home doesn t receive much direct sunlight and is well insulated with properly sealed windows and exterior doors a unit on the lower end of that range would.
For example model gsx140241k is a 2 ton unit.
Air conditioners are sized by the number of btus they put out.
Residential central air conditioners come in a range of sizes from 1 5 ton to 5 ton models.
Higher efficiency units may receive special certification called energy star a department of energy program that recognizes consumer products for their energy saving capabilities.
Btus stand for british thermal units and refer to the amount of energy your air conditioner is using per hour.
There are 12 000 btu s per ton.
Therefore if your home is 2 400 square feet an ac unit that is between three and four tons would likely be a good choice for cooling your space both effectively and efficiently.
This would require 4 39 tons of ac or 455 square feet per ton.
Your hvac unit will need to remove about 4 0 x 12 000 btus or 48 000 btus per hour to keep your home cool.
And if it s too small you won t get enough cool or warm air flowing through your home.
Ac unit size calculator accurately estimates the size of the central air conditioner unit you should install in your house.
Assuming the minimum cooling capacity of 400 square feet per ton for your hvac unit a 1600 square foot home will require 4 0 tons of air conditioning to cool.
Thus a 2 000 square foot area with two windows four regular occupants and one kitchen would have a btu of 52 720.
Get the cost of 1 ton 2 ton 4 ton and 5 ton ac unit.
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.
For example when looking at two different 3 ton air conditioner models one might be rated at 13 seer and the other might be a much more efficient 19 seer unit.
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.
