AC Tonnage: Calculating the Right Match for Your Home


As summer approaches, homeowners often consider upgrading their air conditioning (AC) systems to ensure they stay cool and comfortable during hot weather. One of the most important factors to consider when selecting a central AC unit is its tonnage. But how do you determine the right AC tonnage per square foot for your home? In this blog post, we will discuss how to calculate the tons of a central AC for your house, so you can make an informed decision for your comfort and budget.

What is a Ton of AC and How Does it Impact Your Home’s Cooling Efficiency?

First, let’s define what a ton of AC means. In the air conditioning world, a ton refers to the amount of heat that a particular unit can remove from a space within an hour. One ton of AC can remove 12,000 British Thermal Units (BTUs) of heat in an hour. So, the higher the tonnage of your AC unit, the more heat it can remove from your home per hour. Calculating the tons of AC needed for your home is not a straightforward process, as several factors come into play, such as the size of your home, insulation, ceiling height, number of windows, and the local climate. Here are the steps you can follow to calculate the tonnage of your central AC unit:

Step 1: Calculate the square footage of your home

To determine the size of the AC unit needed, you will need to know the square footage of your home. Measure the length and width of each room in your home, and then multiply these two numbers to obtain the square footage of that room. Add up the square footage of all rooms in your home to determine the total square footage.

Step 2: Determine the cooling capacity per square foot

The industry standard for AC cooling capacity is 1 ton per 600 square feet. However, this can vary depending on your home’s insulation, ceiling height, number of windows, and local climate. For instance, homes in hot and humid areas will require more cooling capacity than those in mild climates.

Step 3: Calculate the required AC tonnage

To determine the AC tonnage per square foot needed, divide the total square footage of your home by the cooling capacity per square foot. For example, if your home is 1,600 square feet, and you need 1 ton of AC for every 400 square feet, you will need a 4-ton AC unit (1,600/400=4).

Step 4: Consult a professional

While the above steps can give you a rough estimate of the tonnage required for your home, it’s always best to consult a professional HVAC contractor. At Ivannova Air Conditioning, we can perform a Manual J load calculation, which takes into account more detailed factors such as window orientation, air infiltration, and heat-generating appliances. This calculation will provide a more accurate tonnage requirement for your home and ensure that your AC unit is sized correctly.
