The cold is concentrated near a window, door, or one room
A localized cold spot with otherwise functioning heat may reflect drafts, blocked airflow, or room balance and can be documented with reversible renter-safe steps.
Why this result fits
- Most of the apartment is adequately warm.
- The coldest area is near a window, exterior door, or one room.
- There is no dangerous cold, equipment warning, or active leak.
What to do now
Map temperatures
Compare the affected room with an interior room using the same thermometer placement method.
Keep heat paths clear
Move belongings away from radiators, baseboards, and supply or return vents.
Use reversible draft control
Use lease-permitted removable weatherstripping, window film, curtains, or a door draft blocker without obstructing egress, vents, or fire doors.
Request inspection if the gap persists
Report failed seals, damaged windows, exterior-door alignment, or a large room-to-room temperature difference.
Stop and escalate if
- The room becomes unsafe or temperature keeps falling.
- A window is cracked, loose, leaking, or required for egress.
- Condensation, ice, or wall damage appears.
What not to do
- Do not permanently caulk windows, cover heaters, or block required ventilation.
- Do not modify a fire-rated corridor door.
- Do not use an unsafe space-heater setup.

Message you can send to maintenance
