As temperatures drop and winter weather settles in, building systems face new risks—and your elevator is no exception. Cold air, freezing pipes, and increased moisture can cause sudden issues that disrupt operations when you least expect it. For property owners and facility managers, winter isn’t just about keeping tenants warm; it’s about protecting mechanical systems that are sensitive to temperature and humidity changes. Elevators are among the most vulnerable. From malfunctioning tank heaters to water intrusion in the machine room, winter conditions can quickly lead to costly repairs and unsafe conditions if not addressed early. This blog will outline essential steps you can take to prepare your elevator for the cold season and ensure reliable performance all winter long.
Why Winter Puts Elevators at Risk
Winter weather affects mechanical equipment in several ways. As temperatures fall, elevator components contract, lubricants thicken, and condensation increases. These changes can cause slow operation, noisy rides, or even system shutdowns. Buildings with older elevator systems or poorly insulated machine rooms are especially vulnerable during extreme cold spells.
Facility managers should consider winterization a vital part of annual maintenance planning. Proactive care keeps your equipment running smoothly and minimizes the likelihood of mid-season breakdowns that inconvenience tenants and disrupt operations.
Protecting Against Freezing Pipes & Water Intrusion
One of the biggest winter-related threats to elevator equipment is water damage—which often comes from frozen or burst pipes. When temperatures drop below freezing, pipes in or near the machine room or hoistway can crack, sending water directly into sensitive electrical components.
Water damage can cause:
-
Electrical shorts
-
Corrosion of components
-
Equipment shutdown
-
Long-term repair costs
Facility managers can prevent this by:
-
Ensuring plumbing lines near elevator systems are insulated
-
Keeping the machine room temperature above the manufacturer’s recommended minimum
-
Scheduling a water intrusion inspection before the coldest months begin
Early detection is key. Even minor leaks can cause major operational problems if ignored.
The Role of Tank Heaters in Winter Reliability
Hydraulic elevators rely on tank heaters to maintain the proper oil temperature. As oil thickens in the cold, elevator performance slows, causing leveling issues, longer travel times, and sometimes system faults. A properly functioning tank heater ensures smooth, reliable operation even on the coldest days.
Key steps for winter readiness:
-
Check tank heaters for proper operation
-
Inspect power supply and thermostat accuracy
-
Verify that the machine room maintains adequate ambient temperature
Neglecting tank heater maintenance can lead to unexpected downtime—something no building wants during a busy winter season.
Moisture Control: Preventing Condensation Damage
Rapid temperature changes increase humidity inside machine rooms and hoistways. Excess condensation can form on equipment, electrical panels, and cables, leading to corrosion or electrical failure.
To control moisture:
-
Seal gaps that allow cold air into the machine room
-
Ensure adequate ventilation without exposing equipment to outdoor temperatures
-
Inspect weather stripping around hoistway doors
-
Schedule routine cleanings to remove dirt and moisture buildup
Taking these steps keeps the elevator’s most sensitive components safe from winter’s harsh effects.
Winter doesn’t have to mean elevator downtime. By preparing your system early—checking tank heaters, preventing water damage, and maintaining consistent machine room temperatures—you can ensure safe, reliable operation all season long. If your building has older equipment or has experienced cold-related issues in the past, now is the best time to schedule a professional evaluation.
A winter-ready elevator not only prevents costly repairs but also keeps your tenants safe and comfortable.
