What Size Air Conditioner Do I Need?

If you’re wondering what size of air conditioner you need, this post is for you. Here’s how to determine what size air conditioner unit will best fit your needs.

Cool Your Room Efficiently

The right air conditioner helps you cool a room efficiently.

An undersized unit won’t cool adequately while one too large will not remove enough humidity, leaving the air feeling damp.

The first thing to consider is “How big a space are you trying to cool?”

Measuring your space helps determine the best window air conditioner unit size to fit your needs.

To calculate the square footage of your space, multiply the length of your room by the width of your room. Measure from the inside of your room.

Use the simple equation of Length In Feet x Width In Feet = Square Footage. Compare the square footage of your room to the list below.

This is how much you can expect a typical window air conditioner unit will cool in total square footage.

What Size Window Air Conditioner Do I Need?

– 150 to 350 sq ft: look for a 5,000- to 8,000-BTU unit
– 350 to 550 sq ft: look for an 8,000- to 12,000-BTU unit
– 550 to 1,050 sq ft: look for a 12,000- to 18,500-BTU unit
– 1,050 to 1,600 sq ft: look for an 18,500- to 25,000-BTU unit


Use the measurements above to get the best air conditioner unit to cool your space.

Does the room you are trying to cool receive a lot of direct sunlight? If so you may need to step up one size to cool it efficiently.

It is also important to determine the power source. Most homes are equipped to run 110 volt units but some have wiring that will support 220 volt units. Larger units often require 220 volts to operate and many homes are not wired to support 220 volt units. These units will cool a larger area but take special plugs and wiring.

Let us help you make sure the unit you pick matches the voltage output in your home.

Lastly, make sure the unit will fit into the window you want to put it in. A lot of times the customer will select a large unit only to find out that the window they want it installed in is too big or small to support the AC unit.
