Exact Room Measurements Mean Lower Cooling Costs
Did you know that many people buy oversized AC units because they think they'll provide better cooling? The truth is that oversized AC units are less effective and waste energy.
Here's Why
AC units remove heat and humidity from the air. Oversized units, though they may cool rooms quickly, only remove some of the humidity. This leaves rooms with a damp, clammy feeling. A properly sized unit will remove humidity effectively as it cools.
Figuring Out the Right Size
To figure out which unit size is best for your cooling needs, you need to determine the square footage of the area to be cooled. For square and rectangular rooms, multiply the length of the area by its width. In triangular areas, you should multiply the length of the area by its width and divide by 2.

Most rooms can be further divided into these basic shapes to determine the square footage. If the shape of your room is something other than square or rectangular, ask your sales associate to help you determine the square footage.
You can also use the square footage and the chart below to determine the correct cooling capacity. Cooling capacity is measured in British thermal units (BTUs) per hour.
| Area To Be Cooled (in Square Feet) | Capacity Needed (BTUs per Hour) |
|---|---|
| 100 to 150 | 5000 |
| 150 to 250 | 6000 |
| 250 to 300 | 7000 |
| 300 to 350 | 7000 |
| 350 to 400 | 9000 |
| 400 to 450 | 10000 |
| 450 to 550 | 12000 |
| 550 to 700 | 14000 |
| 700 to 1000 | 18000 |
| 1000 to 1200 | 21000 |
| 1200 to 1400 | 23000 |
| 1400 to 1500 | 24000 |
| 1500 to 2000 | 30000 |
| 2000 to 2500 | 34000 |
