What should I verify about heating before signing a lease?

Confirm the heating system for the specific unit, how the thermostat/radiators are controlled, whether utilities are included, and what the building’s process is for heat complaints during cold weather.

Does a high “heat” signal guarantee strong heat in every apartment?

No. The filter is based on building-level signals and rated buildings data, but unit conditions and seasonal factors can still affect comfort. Tenant Q&A and unit-specific questions matter.

Where do Openigloo’s heat and condition signals come from?

Openigloo combines signals shown on building pages (including open-data indicators and what renters report in reviews/Q&A). Always treat them as starting points and confirm details directly with the building.

How should I use the 3-train location filter during my search?

Use it to narrow your shortlist, then validate the daily route: check which station entrance is closest, typical walking time, and whether the building’s location changes your commute when you leave at different hours.

Which neighborhoods are trending right now in this scope?

East Village with 11,857+ buildings; Hell's Kitchen with 6,943+ buildings; Yorkville with 9,328+ buildings; Lenox Hill with 8,357+ buildings; Kips Bay with 4,472+ buildings.

What to check before choosing a building highly rated for heat near the 3 train in South Harlem

Confirm what “best-heat” means for each building: read the heat notes in reviews and tenant Q&A, since performance can vary by unit and season.
Verify the commute reality: use the map to confirm the walk time to the 3 train stop you’ll use most, not just the general area.
Ask the super or management about heating responsibilities (thermostat control, radiator vs. central heat, and response times during outages).
Before applying, request the current utility/heat setup for the specific unit and check whether any portion is landlord-paid vs. tenant-paid.
If the building has multiple entryways or wings, ask whether heat results differ by floor or exposure (corner units and top-floor units can behave differently).
