BTU Size Chart

Which BTU rating should I choose?

• The appropriate BTU rating depends on the size of the space you need to heat or cool.
• A higher BTU indicates greater heating and cooling capacity, allowing the air handler to effectively condition larger areas.

*Ceiling height, insulation quality, and local climate can all affect the actual coverage area. For instance, an uninsulated space will need more BTUs to maintain comfort compared to a well-insulated room.
