If you are looking for an easy method that is not based in scientific data try this:
Heating requirement is the same as cooling. To calculate Btu needed to cool look at the furnace for input Btu then multipy that by effeciency of unit.
Now think about the coldest day the furnace will provide okay heating such as 5 degrees outside and 68 degrees inside. Subtract those and you have 63 degrees.
If you heating Btu was 80000 input and 80% efficient, you need 64000 btu to heat 63 degrees.
Do similar math to hottest day and desired inside cool temperature. Maybe 103 degrees outside and 72 degrees inside.
That is 31 degrees difference.
Use heat math of 64000 Btu for 63 degree which is very roughly 1000 Btu per degree.
Apply that to cooling and it's roughly 31000 Btu, or around 2-1/2 ton cooling.
Please don't bark at me about the basic nature of my math-I thought I would explain this as a method to start or get an idea. There is a method that accounts for all factors but no way could I explain it. Also, if using electric heat your btu will be about 4.5 per watt and no efficiency applies. The watts can be found on the inside of the furnace above the blower.

What happens if you install a 2 ton coil to a 3 ton air conditioning unit?
I'm not an air conditioning expert, but I would expect that the compressor will run a lot more than it needs to. A 2 ton coil will not cool as much air as a larger capacity 3 ton coil. Experts?
How do you calculate the excess air in boiler?
To calculate excess air in a boiler, you first need to determine the theoretical air requirement for complete combustion based on the fuel's composition. Then, measure the actual amount of air supplied to the boiler. The excess air percentage can be calculated using the formula: [ \text{Excess Air (%)} = \left( \frac{\text{Actual Air} - \text{Theoretical Air}}{\text{Theoretical Air}} \right) \times 100 ] This calculation helps in optimizing combustion efficiency and reducing emissions.
How do you calculate size of return air grille using cfm?
return grille size times 2 gives u the amount of cfms u are getting out of the return air grille, i.e. 10x10x2=200cfms...
How do i calculate amount of air a furnace is handling?
To calculate the amount of air a furnace is handling, you need to know the furnace's airflow rate, typically measured in cubic feet per minute (CFM). This can often be found on the furnace specifications or determined through airflow measurement tools. Additionally, you can use the formula: Airflow (CFM) = Heating Capacity (BTU/h) ÷ (1.08 × Temperature Rise). This will give you an estimate of the air volume the furnace is processing based on its heating capacity and the desired temperature increase.
