air conditioning calculations rule of thumb

How many square feet is a ton of air conditioning?
Usually, the rule is based on the amount of conditioned floor area, and contractors in many areas generally use the rule of 1 ton of air conditioning capacity for each 400 to 600 square feet of floor area. The rule is usually specified in square feet per ton (sf/ton). The rule doesn’t account for the window type, orientation, or overhang.
What size air conditioner should a contractor install?
When I talk to potential clients, a lot of them tell me their contractor wants to size their air conditioner using a rule of thumb. The rule is usually something like this: Install one ton of air conditioning capacity for every 500 (or 400 or 600) square feet of conditioned floor area.
How much air conditioning do you need for 500 square feet?
The rule is usually something like this: Install one ton of air conditioning capacity for every 500 (or 400 or 600) square feet of conditioned floor area. How far off are they? Let’s take a look. True HVAC designs always start with a load calculation. So we can look at the data.
