What is AC Tonnage?

In HVAC, a "ton" is not a measure of weight, but a measure of cooling capacity. One ton of cooling is the rate of heat removal required to freeze 1 short ton (2,000 lbs) of water in 24 hours. This is equivalent to 12,000 BTUs per hour.

Choosing the correct tonnage is crucial. An undersized unit will run constantly without properly cooling the space, wasting energy. An oversized unit will cool the area too quickly ("short-cycling"), failing to remove humidity effectively and leading to a damp, clammy feeling.

Factors Influencing Cooling Needs

Factor Impact
Square Footage The primary driver of cooling needs. Larger areas require more BTUs.
Climate & Sunlight A home in a hot, sunny climate can require 20-30% more cooling power than a home in a cool, shaded location.
Insulation & Windows Poor insulation and old, leaky windows allow cool air to escape and hot air to enter, increasing the load on your AC.
Occupancy Each person in a room adds body heat, equivalent to about 400 BTUs per hour.
Appliances Kitchens and rooms with large electronics generate significant extra heat, requiring additional cooling capacity.

How to Use the Calculator

  1. Enter the square footage of the room or area you need to cool.
  2. Select the climate description that best matches your area's sun exposure.
  3. Enter the average number of people who will occupy the space.
  4. Specify if the area is a kitchen to account for extra heat from appliances.
  5. Click "Calculate Tonnage" to see the recommended cooling capacity in both BTUs and Tons.

Frequently Asked Questions

What is a BTU?

A BTU (British Thermal Unit) is the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. It is the standard unit of measurement for heating and cooling capacity.

Should I round up or down if my result is between standard AC sizes?

It is generally better to round down or choose the closest standard size that is slightly smaller. Oversizing a unit is often worse than slightly undersizing it because of the humidity problems caused by short-cycling. If you are on the borderline, consulting an HVAC professional is the best course of action.
