Similarly, how do I calculate how many tons of cooling I need? Calculate tons of cooling capacity Tons = BTU/hr. ÷ 12,000. Oversize the chiller by 20% Ideal Size in Tons = Tons x 1.2. You have the ideal size for your needs.
Keeping this in view, how many tons of cooling do you need per square foot?
Simple answer: You need 0.0016 tons of AC per square foot. In general, for every 600 sq ft, you need 1 ton of AC. This is a general estimate. You can insert the area and calculate how many tons of AC you need per certain square footage.
How many square feet does a 2 ton AC cool?
Units that are 2 tons can cool off 901-1200 square feet spaces. Units that are 2.5 tons can cool off 1201-1500 square feet, etc. This pattern continues up to units of 5 tons that cool off 2401-3000 square feet, with every half ton increase adding about an additional 300 square feet.

How do I calculate HVAC size?
How to Determine the Size of HVAC You Need- First, determine square footage: Find out the floor space in your home.
- Second, determine the base BTU: The unit used to measure energy used for heating and cooling is the British Thermal Unit, or BTU.
- Third, account for high ceilings: If your home's ceiling is over 8 feet, multiply the base BTU amount by 1.25, or 25%.

What size of AC unit do I need?
As a rule of thumb, an air conditioner needs 20 Btu for each square foot of living space. But other considerations, such as the ceiling height and the size of your windows and doorways, might call for more cooling power. To measure your room, multiply the length by the width.How AC tonnage is calculated?
To estimate your AC tonnage needs, multiply the number of square feet you're cooling times 25. This equals the total number of BTUs you need to adequately cool your space. Next, divide that number by 12,000 to determine the tonnage capability you need in your new air conditioning unit.How many BTU do I need for a 12x12 room?
