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 square feet will a 3 ton AC cool?
3-ton is equal to 36,000 BTU. If you apply the 20 BTU per sq ft rule of thumb, you can see that a 3-ton air conditioner cools about 1,800 square feet spaces.
How many sq ft will a 2.5 ton AC cool?
For example, a 30,000 BTU, 2.5-ton air conditioner is made to effectively cool a home between 1,200 and 1,500 square feet. A slightly larger 3,600, 3-ton unit, is designed for homes that are 1,500 to 1,800 square feet.

Can you replace a 2 ton AC unit with a 3 ton?
Simple answer: yes. But that really depends on the size of you house and its condition. If the 2 ton unit is working as designed but seems to run continuously without satisfying the thermostat setting, then it might be undersized and replacing it with a 3 ton unit might be the answer.

What size AC do I need for 1200 sq ft?
STEP 1: Determine how many BTUs of heating and tons of AC you need House Square Footage BTUs Needed 500 – 700 14,000 700 – 1,000 18,000 1,000 – 1,200 21,000 1,200 – 1,400 23,000.
What size AC do I need for 1800 sq ft house?
Here’s some math: You need around 20 BTUs per square foot, which is equivalent to 0.0016 tons. For example, a 600-square-foot space requires a 12,000 BTU or 1-ton unit. By those calculations, an average 1,800-square-foot house would need a 3-ton central air conditioning unit.

Is 3 ton AC big enough?
Pro Tip: as a rule of thumb, the maximum AC unit size you need to install should not be more than 15% more than the BTU’s you need to cool your house.
