How to Choose a Room Air Conditioner
Compared to large capacity central units, room air conditioners have several advantages. The initial cost of a room air conditioning unit is significantly lower than the cost of central air. Because room air conditioners are designed for cooling small spaces, operating costs are reduced. And, room air conditioners can provide personalized temperature and humidity controls that central systems cannot.
Calculating Cooling Capacity
Cooling capacity is the critical factor in properly selecting a room air conditioner. Cooling capacity is measured in British Thermal Units (BTUs) and typical models will range in capacity from 5,000 BTUs to 28,500 BTUs.
Choosing an undersized unit will overwork the unit and it will not cool properly. Choosing an over-sized unit will cost more to buy and operate and it will not dehumidify properly.
We can help you to calculate capacity. Be prepared to provide specific information on:
- Room Dimensions
- A simple floor plan to show the location of doors and north-facing windows
- The number of people it will serve
- Sources of heat such as lamps, TV and appliances
- An explanation of what's above the intended room
- Your insulation provisions
Cooling Capacity by Room Size
Measure the length and width of the area to be cooled. Multiply the length by the width to determine square footage or square meters. Locate the room size in the chart below to select the appropriate BTUs. Then use the product information to select the unit for your room. When cooling rooms with uninsulated ceilings, great rooms, or southern or western sun exposures - step up to the next BTU size.
| Room Size | BTU |

| Sq. Ft. | Sq. m | |
| 150 | 14 | up to 5,000 |
