There are many factors that go into a load calculation. It sounds like the contractors built an efficient house and sized the hvac system appropriate for your home.Įvery building is unique and each one requires load calculations to properly size the hvac system to match it. Sizing an HVAC system by square footage is a very crude general rule of thumb. If you have any questions, you can pose them in the comments below. 5-Zone Mini Split ACs: About 4 Tons or 48,000 BTU.4-Zone Mini Split ACs: About 3 Tons or 36,000 BTU.3-Zone Mini Split ACs: About 3 Tons or 36,000 BTU.Dual Zone Mini Split ACs: About 2 Tons or 24,000 BTU.Single Zone Mini Split ACs: 1 Ton or 12,000 BTU.When you calculate the tonnage, you can check out several 1-4 ton mini-split air conditioners here: You can insert the area and calculate how many tons of AC you need per certain square footage. Here is the formula:ĪC Capacity (Tonnage) = (INSERT AREA IN SQ FT) * 0.0016 tons/sq ft You can use the ‘tonnage per square foot’ formula to calculate how many tons of AC you need. In general, for every 600 sq ft, you need 1 ton of AC. In short, if you’re looking to cool down a 600 sq ft area, you would need:ĪC Capacity = 600 sq ft * 0.0016 tons/sq ft = 1 Ton
Simple answer: You need 0.0016 tons of AC per square foot. Here is the most frequently asked question about tonnage, BTU, and area (square footage): How Many Tons Of AC Per Square Foot? (Tonnage Per Square Foot) You can check which of these 12,000 BTU mini splits are the best to use here. You can check the best central air conditioners with prices of 2, 3, 4, 5, 6 ton AC units here.Įxample 3: 1 ton AC covers how many square feet?ġ ton AC covers 600 square feet. 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 square feet does a 3-ton air conditioner cover is quite easy to answer as well. A 1.5-ton AC unit covers 900 square feet of living space.Įxample 2: How many square feet does a 3-ton air conditioner cool? The calculator below can find the missing value in the formula above, provided that all other values are given.Example 1: 1.5 ton AC covers how many square feet? Note that this relationship does not apply if a phase change is encountered, because the heat added or removed during a phase change does not change the temperature. Thus, the relationship between heat and temperature change is usually expressed in the form shown below: However, in school problems we usually use a constant specific heat at standard pressure. So, the formula below would be somewhat more correct as: These include the starting and ending temperature, as well as the pressure and the volume of the system before and after heat is added. The heat capacity can be affected by many of the variables of state that describe the thermodynamic system under study. The specific heat capacity, often called simply specific heat, is the heat capacity per unit mass of a material.įrom this definition we have the following formula for specific heat: Heat capacity – or thermal capacity – is a measurable physical quantity equal to the ratio of the heat added to (or removed from) an object to the resulting temperature change.The standards-based unit in the International System of Units (SI) is the joule (J). Historically, many energy units for measurement of heat have been used. Heat is the amount of energy flowing from one body of matter to another spontaneously due to their temperature difference, or by any means other than through work or the transfer of matter.
