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 does a 3-ton AC unit cover?
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 4 ton AC unit cool?

How do you figure out what size HVAC you need?
To calculate the size of the air conditioner you need for a room, first, multiply the length of the room with its width. Then multiply it with 25 BTU to get the ample cooling for the room under different weather conditions. For example, if the room is 15 feet long and 12 feet wide, it comes to 180 square feet.
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.
Is the a big difference between a 2.5 ton and 3 ton AC?
The general guideline is a 2.5 ton unit for a home that’s 1,500 to 2,000 square feet. A 3 ton unit is ideal for a home that’s 2,000 to 2,500 square feet.
Is 2.5 ton AC big enough?
According to this common but somewhat inaccurate method, you need 1 ton of air cooling capacity for every so many square feet of living space. While there’s some dispute over the exact amount, an often-used amount is 600 square feet. A 2.5-ton unit, then, theoretically would fit a 1,500-square-foot home.
How much does a 4 ton HVAC system cost?
Average AC Unit Prices by Size or Capacity Central AC Unit Size AC & Coil AC & Coil Installed Cost 2.5 Tons, 30,000 btu $1,525 $2,695 3 Tons, 36,000 btu $1,650 $2,990 3.5 Tons, 42,000 btu $1,780 $3,250 4 Tons, 48,000 btu $1,860 $3,350.
What happens if AC unit is too big?
An oversized HVAC unit can make your home’s inside temperature uncomfortable. An HVAC system with excess capacity can heat or cool your home faster, but that speed often results in a couple of other issues. As a result, you could end up with a number of hot or cold spots throughout your home.
What size AC unit do you need for a 2000 sq ft house?
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 tonnage is calculated?
tonnage, in shipping, the total number of tons registered or carried or the total carrying capacity. Gross tonnage is calculated from the formula GT = K1V, where V is the volume of a ship’s enclosed spaces in cubic metres and K1 is a constant calculated by K1 = 0.2 + 0.02 log10 V.
What size AC unit do I need for a 1300 sq ft house?
When looking for the quick answer to how much air-conditioning power you’ll need to adequately cool a 1,300-square-foot space, the answer is 23,000 BTUs per hour of air conditioning power. This is the base capacity needed for a 1,200- to 1,400-square-foot house.
What size AC unit do I need for a 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.
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.
Is a 3 ton air conditioner 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. This means that if your house requires a 24,000 BTU unit (2 tons), you should not install one that is larger than 30,000 BTU’s (3 tons) to maintain energy efficiency.
Is a 2 ton AC big enough?
For those of you that don’t understand the way AC systems work, a 2-ton unit typically provides cooling for about 900-1,400 square feet of space – give or take.
What size furnace do I need for a 3 ton AC unit?
In the case of a 1500 sq. ft. home, the air conditioner would need to be 37,500 ÷ 12,000, which comes out to about 3 tons. For the furnace, an 80% efficiency unit would need a BTU output of about 37,500 × 0.8, which is about 47,000 BTU.
What is the average cost of a 2.5 ton air conditioning unit?
Average cost: $3,200 – $7,800 For a 1,300 to 1,600 square ft home you would want a 2.5 ton AC unit and the average installation cost would be around $3,570 with the unit alone costing around $1,285. Read more about these cost factors below.
