How many square feet will a 2 and 1/2 ton AC unit cool?
Air conditioners that are 1.5 tons can cool off a space that is 600-900 square feet. 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.
What size HVAC do I need for 2500 sq ft?
Step 5: Match your square footage to an HVAC size chart
| Home Sq Footage | Air Conditioner Size (tons) |
|---|---|
| 600 – 1,000 square feet | 1.5 tons |
| 1,000 – 1,500 square feet | 2 tons |
| 1,500 – 2,000 square feet | 3 tons |
| 2,000 – 2,500 square feet | 4 tons |
How do you determine AC tonnage?
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.
What is the thumb rule for AC tonnage calculation?
The most basic thumb rule to get started is to calculate the volume of your room in feet and divide it by 1000, this will give you the required capacity in TR (tons). So a 10 foot by 10 foot room which is 10 feet high will need a one ton AC (10’x10’x10′ = 1000 Cu. ft. / 1000 = 1 ton).
How many tons does a 3000 square foot house need?
1 ton equals 12,000 BTU. That means that, on average, we will need 0.0016 tons per square foot….Tonnage Table.
| Area (Square Feet): | BTU | Tonnage |
|---|---|---|
| 2,700 sq ft | 54,000 BTU | 4.5 Tons |
| 3,000 sq ft | 60,000 BTU | 5 Tons |
| 3,300 sq ft | 66,000 BTU | 5.5 Tons |
| 3,600 sq ft | 72,000 BTU | 6 Tons |

How to calculate HVAC load?
To calculate the estimated HVAC load for a house with 2,500 square feet, 12 windows, and 3 exterior doors occupied by 4 people, simply plug it into this formula: 2,500 x 25 = 62,500 base BTU 4 people x 400 = 1,600 12 windows x 1,000 = 12,000
How many BTU per square foot do I Need?
The general rule of thumb is that furnaces need to provide 25 to 30 BTU output per square foot in moderate climates and 40 BTU output per square foot in colder regions. The furnace output is less than its input. This difference is the unit’s efficiency, and manufacturers express it as a percentage.
