Zones

A zone refers to a specific area you want to heat or cool. Typically, a zone is an enclosed space, such as a kitchen, living room, bedroom, or garage. The square footage is calculated based on 8-foot ceilings. If your ceilings are higher or lower than 8 feet, use our square footage calculator to determine the appropriate coverage for your space.

Air Handler BTU Guide

To determine the appropriate BTU rating for your space, start by measuring the square footage of the area you want to heat or cool.

Factors to Consider:

Insulation: Poor insulation may require a higher BTU rating.
Climate: Extremely hot or cold climates may also necessitate additional BTUs for optimal performance.

Coverage Area Guidelines:

9,000 BTU: Suitable for spaces up to 375 sq. ft.
12,000 BTU: Ideal for areas between 350–550 sq. ft.
18,000 BTU: Covers spaces from 550–800 sq. ft.
24,000 BTU: Best for areas measuring 800–1,050 sq. ft.
36,000 BTU: Designed for larger spaces between 1,050–1,550 sq. ft.

Ceiling Cassettes only come in 9k, 12k, & 18k options.

This will be used to connect the indoor unit (air handler or cassette) with the outside unit (condenser).
