Plan each zone before selecting the outdoor unit
Provide the loads and intended use of each zone. Rooms with different exposures or schedules may call for different indoor capacities. The outdoor unit’s nameplate capacity is not a substitute for reviewing the proposed combination.
Combination data matters
Verify allowed indoor units, connected capacity limits, and capacity allocation using the selected outdoor model’s documentation. Check heating performance for the complete match and confirm any operating restrictions.
What to include in your request
- Number of zones and the preferred indoor-unit type for each.
- Individual room loads and overall heating/cooling requirements.
- Proposed indoor and outdoor model numbers, if selected.
- Line-set routes, approximate lengths, and job timing.
