How Many Square Feet Can a 5 Ton AC Unit Cool? - A Comprehensive Guide

When it comes to cooling your home, it's important to understand the size of the air conditioning unit you need. But how many square feet can a 5-ton AC unit cool? The answer is that it will cool it down quickly, but the air conditioning unit will never be able to remove moisture. To achieve this, you need two-stage condensers and air treatment systems with variable speed drives. To take into account the size of the house, we can divide the load or capacity by the floor area, but the numbers would be small.

For example, a 3000 square foot house with a 3 ton air conditioner would have 3 ÷ 3000 = 0.001 tons per square foot. By investing, we get a nicer number, 1000 square feet per ton. Of the 167 zones, only 53 were less than 1000 square feet per ton and only 20 areas were less than 700 square feet per ton. This means that only 12% of the areas in this group could have been close to having refrigeration equipment of the right size, according to the rule of 400 to 600 square feet per ton. The average load of the 75 homes was about 1200 square feet per ton.

In those 63 homes, we selected 151 individual heating and cooling systems. As you can see, here the columns have been shifted to the left, indicating that the air conditioning equipment we chose was larger than the loads. That's why the average capacity of the systems we selected was 856 square feet per ton, making our average capacity 28% higher than the average cooling load (1192 square feet per ton). Designing an air conditioning system starts with getting the right size. Look at the number of square feet per ton to see if you're in the ballpark.

If the number is less than 1000 square feet per ton for newer homes, then either the number is wrong or the house isn't as efficient as it should be. For instance, with a 1-ton Midea modular vibrator (basically a mini-split in a can) mounted on the window of my approximately 2400 foot vintage house from the 1920s, while all interior doors remain open, it covers 100% of my 1% cooling load (1% local temperature container = 83°F) at an average indoor temperature of mid-70s F. That's a ratio of tons to 2400 feet under design conditions. Without the window unit turned on, with an oversized central air with 5-ton ducts, the duty cycle never exceeds ~ 50%, even when outdoor temperatures are around 90°F (like now), implying a load ratio of one ton per 1000 feet at outdoor temperatures 10 °F or more ABOVE design temperature of 1%.It's also pretty easy to tell how many square feet a 3-ton air conditioner can cool. If you apply the general rule of 20 BTU per square foot, you'll see that a 3-ton air conditioner cools approximately 1,800 square feet of space.

When selecting an AC unit for your home or office space, it's important to understand how many square feet each unit can cool. A 5-ton AC unit will cool down your space quickly but won't be able to remove moisture from your home or office. To achieve this goal you need two-stage condensers and air treatment systems with variable speed drives. To determine what size AC unit you need for your space you need to calculate how many BTUs are needed per square foot in your area and divide that by 1000 to get an estimate of how many tons are needed for your space. Generally speaking, newer homes should have an AC unit that is less than 1000 square feet per ton while older homes may require more than 1000 square feet per ton. It's also important to consider other factors such as outdoor temperatures and efficiency when selecting an AC unit for your home or office space.

By understanding these factors and calculating how many BTUs are needed per square foot in your area you can ensure that you select an AC unit that is best suited for your needs.
