NYC AC BTU Calculator
Estimate BTUs and tonnage for a single room — built for NYC realities like kitchens, uneven sunlight,
and higher ceilings. Use this as a planning estimate for mini-splits, VRF systems, and apartment HVAC upgrades.

How this NYC BTU estimate works
The calculator starts with a baseline of approximately 20 BTUs per square foot for a typical room, then applies
NYC-oriented adjustments: kitchens add heat load, hallways typically need less capacity, and sun exposure changes demand.
If your ceilings are 9ft or higher, we add a volume factor because the system must condition more air.

- Initial VRF zoning conversations
- Apartment HVAC replacement planning
- Quick “is this wildly undersized?” check
- Multiple rooms / multi-zone systems
- Co-ops/condos with strict equipment rules
- Commercial spaces with high internal loads
- Comfort issues, short-cycling, or poor airflow
