A two-ton air conditioner removes 24,000 BTUs per hour. When an air conditioner is listed by BTUs rather than by tonnage, it’s usually referring to BTUs per hour, so the two measures are directly comparable if you multiply or divide by 12.
How many BTUs is a 4 ton unit?
The measurement for heat is the British thermal unit (BTU). One ton of air conditioning can remove 12,000 BTUs of air per hour. A four ton unit can move 48, 000 BTUs and so on.
How many square feet can 1 ton cool?
The smallest residential unit is 1.5 tons (18,000 BTU) and the largest is 5 tons. On average you need 1 ton of cooling for every 1000 square feet of home.
How do I know if my AC unit is big enough for my house?
Rule of Thumb — The maximum size unit you should buy would be 15% over the BTUs you need for cooling and 40% of the BTUs for heating. The max for heat pumps is 25%, since it handles both cooling and heating.
How many BTU is a 2 ton furnace?
So a 2-ton unit has 24,000 BTU/hr capacity and a 3-ton has 36,000 BTU/hr, and so on.
How many BTUs is a 5 ton air conditioner?
Average Cooling Capacity
One ton of cooling capacity equates to 12,000 BTUh. For homeowners, residential air conditioners usually range from 1.5 to 5 tons or, 18,000 – 60,000 BTUh.
Can I replace a 3 ton AC with a 4 ton?
Proper size is a must. There is no reason for you to install a 4 ton if you can use a 3 ton. The low stage isn’t that much less than full capacity because of the unloading scroll systems.
What does SEER mean in HVAC?
SEER stands for Seasonal Energy Efficiency Ratio—a rating system of the air conditioner’s cooling capacity to power input. In technical terms, it’s the ratio of the amount of cooling produced (in British Thermal Units, or BTUs) divided by the amount of electricity (in watts) used.
What SEER AC should I get?
For most homeowners, opting for a unit with a SEER between 15 and 18 is a good choice because it’s a balance between the money you’ll spend for the unit and the amount you’ll save on utility costs.
What size air conditioner 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 house will a 5 ton air conditioner cool?
Most homes from about 2500 to 3000 square feet require a 5 ton air conditioner.
