How do I know if my AC unit is the right size?
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.
What size air conditioner do I need for a 1,500 square foot house? A 2.5 ton air conditioner is best because about 30,000 BTU is needed for a house that's 1,500 square feet.
Is a 3-ton air conditioner enough for my house? Apart from the capacity of the air conditioner, you also need to account for things like your climate, house size, and existing insulation. In general, a 3-ton air conditioner will work well in an area of around 1,200 square feet.
First, find out your the area of you room. Then divide it by 600 to get the basic capacity. So, if you room is 100 sq. feet, the basic AC capacity required will be 0.167 tons (100 / 600).
1,201 to 1,500 square feet homes should use 2.5 tons. If your home size is higher than the number above but is less not more than 1,800 square feet, you can go for a three-ton A/C.
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. First, your home won't benefit from gradual, even heating and cooling.
A 2-ton split AC is best suited for larger rooms, measuring up to 240 sq. ft of space.
The recommended capacity for a home that is 1,201 to 1,500 square feet is 2.5 tons. For a home 1,501 to 1,800, the recommended capacity is 3 tons. For a 2,000 square-foot home, the best AC capacity is 3.5 tons. Since larger homes are costlier to cool, you'll need a 5-ton unit to cool a 3,000 square-foot home.
Square Footage | BTUs per hour | AC Unit Tonnage |
---|---|---|
1,200 to 1,400 | 23,000 | 2 Tons |
1,400 to 1,500 | 24,000 | 2 Tons |
1,500 to 2,000 | 30,000 | 2.5 Tons |
2,000 to 2,500 | 34,000 | 3 Ton |
Is 3 ton AC too big?
While a local HVAC professional can help you with this, the general rule of thumb is that one ton of AC capacity will cool approximately 500 square feet. So if your home is 1,500 square feet, a two to three-ton unit would be best.
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 2 ton AC coverage area? The room size for 2 ton AC will be around 200 to 240 square feet. However, the figure will be between 180 and 200 if the space is a cooling facility for equipment or an electrical panel room. This is the 2 ton AC cooling capacity you must know.
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.
Room size and power consumption
For instance, a 1-ton window AC or a 1.5 ton split AC is an ideal choice for rooms measuring up to 150-160 sq ft.
House square footage * | Furnace Output [BTU/hr] | Air Conditioner size [ton] |
---|---|---|
1300 to 1700 sq ft | 45,000 BTU/hr | 2 ton |
1700 to 2500 sq ft | 55,000 BTU/hr | 2.5 ton |
2500 to 3500 sq ft | up to 65,000 BTU/hr | 3 to 3.5 ton |
3500 to 4500 sq ft | up to 80,000 BTU/hr | 4 to 5 ton |
