NYC Seasonal Maintenance Checklist

A simple seasonal routine helps catch small apartment maintenance issues before they become a last-minute punch list.

NYC apartments deal with humid summers, cold winters, window AC units, steam or hydronic heat, and a lot of daily wear. The exact maintenance responsibilities depend on your lease, building and equipment, but this checklist is a useful starting point.

🌸 Spring

• Check window AC units and clean or replace filters according to the manufacturer’s instructions.
• Inspect accessible window and door caulk or weatherstripping for visible gaps.
• Test smoke and CO alarms according to the device instructions and building requirements.
• Report persistent slow drains or leaks before they become larger problems.

☀️ Summer

• Watch window AC units for drainage problems or water reaching the sill or facade.
• Clean accessible AC filters and keep intake areas clear.
• Check bathroom ventilation and visible moisture buildup.
• Inspect accessible caulk around tubs and showers for gaps or peeling.

🍂 Fall

• Test heating early enough to report noise, leaks or cold spots before the coldest weather.
• Do not alter radiator valves, vents or building heating equipment if you are unsure of the system; contact the super or appropriate heating professional.
• Check weatherstripping around doors and windows for drafts.
• Confirm doors and windows still open, close and latch normally.

❄️ Winter

• Report exposed or vulnerable plumbing in cold areas to the building or appropriate plumbing professional.
• Watch for condensation, drafts and water intrusion around windows.
• Keep heating equipment clear of stored items and follow building guidance.
• Do not block required exits or egress windows with furniture or storage.

🛠 Anytime

• Tighten simple loose cabinet hinges and door handles where appropriate.
• Touch up wall scuffs and patch small holes that are within your repair scope.
• Re-check furniture anchors and mounting hardware.
• Keep a running punch list so compatible general repair tasks can be grouped together.
