How Cold Winters Affect Elevator Performance and What to Do to Prepare Your Elevator for Winter Weather

By the Quality Elevator Company Team

Winter weather presents a distinct set of mechanical and operational challenges for elevators in the Mid-Atlantic and DC metro region. From the frigid January temperatures that grip Pennsylvania and western Virginia to the wet, freeze-thaw cycles that stress equipment in Maryland and the District of Columbia, building owners who wait until problems appear often face costly breakdowns, code violations, and service disruptions. This guide explains exactly what happens to an elevator in cold weather and provides a practical, step-by-step preparation protocol for owners across DC, Maryland, Pennsylvania, and Virginia.

What Happens to an Elevator When Temperatures Drop?

An elevator is a complex electromechanical system, and nearly every major subsystem responds to cold in some way. Understanding which components are most vulnerable helps building managers prioritize their winter maintenance spending and schedule service before problems arise.

Hydraulic Fluid Viscosity

Hydraulic elevators rely on fluid pressure to raise and lower the cab. When ambient temperatures fall significantly, hydraulic fluid thickens and its viscosity increases. Thicker fluid flows more slowly through the pump and valve system, which means the elevator may move more sluggishly, level imprecisely at floors, or fail to respond at all when oil becomes too viscous to flow. Machine rooms that are unheated or poorly insulated are especially susceptible. The appropriate fluid type and viscosity grade for cold-weather operation should be verified during a pre-winter service visit.

Lubrication Breakdown

Guide rails, cables, roller guides, and mechanical components all depend on lubricants that are formulated to remain consistent across a temperature range. Grease and oil that perform well at room temperature can stiffen, separate, or fail to coat properly when temperatures approach freezing. Inadequate lubrication accelerates wear on guide shoes, increases vibration, and can generate unusual noise — all early warning signs that a building manager should not ignore.

Electrical and Control System Stress

Control boards, relay panels, and motor controllers contain electronic components whose performance is sensitive to temperature extremes. Cold temperatures can cause contraction in circuit board materials and connectors, potentially creating intermittent faults. Condensation is an additional risk: when a cold machine room warms rapidly — such as during the heating cycle of the building’s HVAC system — moisture can condense on electrical components, increasing the risk of corrosion and short circuits.

Door System and Safety Devices

Elevator door operators, rollers, and tracks can stiffen in cold weather, causing doors to open or close more slowly than designed. Door safety edges and light curtains — which are critical life-safety devices governed by the ASME A17.1/CSA B44 Safety Code for Elevators and Escalators — must function reliably regardless of temperature. Cold-related stiffness that causes a door to resist reopening is a code compliance issue, not merely an inconvenience.

Machine Room Temperature Requirements

The ASME A17.1/CSA B44 Safety Code establishes requirements for machine room environments to protect equipment from temperature extremes. Building owners are responsible for maintaining machine room conditions within ranges that support proper equipment operation. When building heating systems are shut down or fail during winter, machine rooms can quickly drop to temperatures that compromise equipment reliability.

Metal Contraction and Structural Stress

Elevator rails, cables, and structural components are made of steel and other metals that contract when cold. While well-designed elevator systems account for thermal expansion and contraction, extreme or rapid temperature swings — particularly in older equipment — can place additional stress on anchor points, brackets, and guide rail joints.

What Are the Most Common Winter Elevator Failures?

Based on the mechanical principles above, the failure modes that become more common during winter months include:

• Slow or erratic leveling caused by thickened hydraulic fluid
• Door nuisance faults resulting from stiff operators, rollers, or tracks
• Control system faults triggered by temperature-related electrical issues or condensation
• Increased vibration or noise from inadequate lubrication on guide systems
• Emergency recall and firefighter service malfunctions caused by cold-stiffened switch contacts or corroded terminals
• Hydraulic unit failures in systems with worn or incorrect-viscosity fluid

Each of these failure modes has the potential to take an elevator out of service during the period of highest demand — the winter months when building occupants are least willing to use stairways. Quality Elevator Company approaches winter preparation as a proactive risk-reduction service, addressing these vulnerabilities before the first cold snap arrives.

How Do Winter Conditions Affect Elevator Compliance in DC, Maryland, Pennsylvania, and Virginia?

Building owners have a legal obligation to maintain elevators in safe operating condition and in compliance with applicable codes. Winter-related equipment degradation does not pause those obligations.

In the District of Columbia, the DC Department of Buildings (DOB) requires all elevators to be inspected and certified. DC has adopted the ASME A17.1/CSA B44-2013 edition as referenced by the 2017 DC Building Code. Category 1 inspections are required every 12 months and Category 5 inspections every 60 months, each conducted by an ASME QEI-certified inspector from a DOB-approved third-party agency. In buildings with passenger elevators, at least one elevator must remain in operation whenever the building is occupied. A winter equipment failure that takes the only operable elevator out of service is not merely inconvenient — it may constitute a violation of DC requirements.

In Maryland, the Maryland Department of Labor, Division of Labor and Industry, Elevator and Escalator Safety administers the state’s elevator program under the Annotated Code of Maryland, Public Safety Article, Title 12, Subtitle 8. Maryland adopted the ASME A17.1/CSA B44-2022 edition (effective June 17, 2026), and each elevator unit must receive a periodic annual inspection. The certificate of operation must be posted conspicuously in or on the elevator. A winter breakdown that results in an uncertified unit remaining out of service without proper notification can carry regulatory consequences.

In Pennsylvania, the Pennsylvania Department of Labor and Industry, Bureau of Occupational and Industrial Safety, Elevator Section oversees elevator safety statewide under 34 Pa. Code Chapter 405. Electric and hydraulic elevators must have periodic inspections at intervals no greater than six months. Pennsylvania is also transitioning to ASME A17.1-2016 for permit applications made on or after December 20, 2026. Owners who experience winter failures resulting in repairs or alterations will need to ensure compliance with the applicable code edition before the equipment returns to service.

In Virginia, elevator inspection and enforcement fall to local building departments under the Virginia Uniform Statewide Building Code (13VAC5-63), which incorporates the ASME A17.1/CSA B44-2019 edition (effective January 18, 2024). All elevators and escalators require an annual periodic inspection, and a locality may require six-month inspections. The current certificate of inspection must be displayed in the elevator or kept available in an approved location. Virginia elevator mechanics must hold state certification, and contractors must carry an Elevator/Escalator Contracting (EEC) specialty license from the Virginia Board for Contractors.

What Steps Should I Take to Prepare My Elevator for Winter? (Step-by-Step Protocol)

The following protocol reflects industry best practice for winter elevator preparation in DC, Maryland, Pennsylvania, and Virginia. Building owners and property managers should initiate this process before sustained cold weather arrives — ideally in early to mid-autumn.

1. Schedule a pre-winter maintenance visit. Contact a licensed and qualified elevator service provider to perform a comprehensive inspection of all major systems before temperatures fall. In Maryland, work must be performed by a mechanic licensed by the Maryland Elevator Safety Review Board. In Virginia, mechanics must hold state certification. In DC, work must be done by a contractor holding a DC elevator contracting license issued through the Board of Industrial Trades.
2. Inspect and test the machine room heating system. Verify that the machine room is heated and that the heating system is functioning. Confirm that the thermostat is set and operating. A cold machine room is the single most common root cause of winter elevator failures.
3. Check hydraulic fluid condition and viscosity rating. For hydraulic elevators, have a technician verify that the fluid is at the correct level, is free of contamination, and is a viscosity grade appropriate for the expected winter operating temperatures. Replace or supplement fluid if it does not meet cold-weather specifications.
4. Lubricate all moving components. Rails, cables, guide shoes, roller guides, door operators, and mechanical linkages should all be lubricated with products rated for low-temperature performance. Remove any dried, hardened, or contaminated lubricant before applying fresh material.
5. Inspect and test all door systems. Check door operator drive systems, rollers, tracks, and timing. Test all door safety devices — safety edges, light curtains, and reopening mechanisms — to verify they respond correctly at current and anticipated temperatures. Door safety device function is a core requirement under the applicable edition of the ASME A17.1/CSA B44 Safety Code in all four jurisdictions.
6. Inspect electrical connections and control panels. A technician should check all terminal connections for corrosion, tighten any loose connections, and inspect the control panel for signs of moisture intrusion. Verify that all safety relays and contacts operate correctly.
7. Test emergency power, lighting, and communication systems. Emergency lighting, the two-way communication device (required under the applicable ASME A17.1/CSA B44 edition in each jurisdiction), and any backup power connections should be tested and confirmed operational. Cold weather increases the risk of power outages, making reliable emergency systems especially critical.
8. Check pit conditions for water intrusion. Elevator pits are vulnerable to water intrusion from snowmelt, ice, and ground moisture during winter. Inspect the pit for standing water, verify that the pit drain or sump is functional, and confirm that the pit stop switch and safety devices are dry and accessible.
9. Review your maintenance records and certificate status. Confirm that the current certificate of inspection is properly displayed and that no upcoming required inspection or test deadlines fall during the winter months. In Maryland, maintenance, repair, test, and inspection records must be kept at a readily accessible central location in the building.
10. Establish a winter emergency contact protocol. Ensure that building staff know how to reach the elevator service provider for after-hours emergencies, understand how to initiate an emergency recall to release a trapped passenger, and know when to contact local emergency services if a passenger is entrapped.

How Does Cold Weather Affect Hydraulic Elevators Differently Than Traction Elevators?

Hydraulic and traction elevators share some winter vulnerabilities — both have electrical systems and door mechanisms that cold can affect — but their primary operating systems respond to temperature in different ways.

Hydraulic elevators are more directly sensitive to low temperatures because their entire lifting mechanism depends on fluid dynamics. The pump motor, hydraulic fluid, cylinder seals, and valve assembly all perform differently as temperature falls. Cold fluid requires the pump to work harder, stresses seals, and can cause jerky or slow movement. Hydraulic elevators in unheated or partially heated machine rooms are at the greatest risk of cold-weather performance issues.

Traction elevators — which use steel wire ropes, a motor, and a counterweight system — are less directly affected by fluid viscosity, but their motors, gearboxes (in geared traction systems), brakes, and control systems are all influenced by temperature. Gearbox lubricants can thicken in cold conditions, and brake components may require careful adjustment in winter to ensure proper holding force without excessive wear.

Machine-room-less (MRL) traction elevators, which have grown in prevalence in newer Mid-Atlantic construction, locate their drive and control equipment within the hoistway itself. This configuration can expose electronic components to temperature swings that a traditional machine room — with its dedicated heating — would moderate. MRL systems warrant particular attention during winter preparation.

What Are the Signs That Cold Weather Has Already Damaged My Elevator?

Building managers should watch for the following warning signs during the winter months, as each may indicate a temperature-related issue requiring prompt service:

• The cab moves unusually slowly, especially on initial startup in the morning
• The elevator fails to level accurately at floors, leaving a gap between the cab threshold and the floor landing
• Doors open or close more slowly than usual, hesitate, or reverse unexpectedly
• Unusual vibration, grinding, or squealing sounds during travel
• Control faults or error codes appearing on the controller display
• The elevator goes out of service on cold mornings but recovers as the machine room warms
• The emergency light activates unexpectedly or the two-way communication device produces poor audio
• Standing water or ice is visible in the pit

None of these symptoms should be treated as normal winter behavior. Each represents a condition that, under applicable codes across DC, Maryland, Pennsylvania, and Virginia, requires evaluation and correction by a qualified elevator professional.

How Much Does Winter Elevator Preparation Typically Cost?

The cost of a pre-winter elevator maintenance visit varies based on the number of elevators, equipment type, age, condition, and what work is identified during the inspection. Factors that typically drive cost upward include older equipment with worn components, hydraulic systems requiring fluid replacement, multiple elevators in a single building, and locations with machine rooms that require separate heating repairs.

Comparing the cost of proactive winter maintenance to the cost of an emergency repair or a regulatory violation illustrates why preparation is the more economical approach. Emergency service visits, parts procurement under time pressure, and potential fines or certificate suspensions from regulatory agencies represent costs that routine maintenance is specifically designed to prevent.

Quality Elevator Company provides transparent assessments before beginning work, so building owners in DC, Maryland, Pennsylvania, and Virginia can make informed decisions about what their systems need going into winter.

Are There Specific Regulatory Deadlines I Need to Know About for Winter 2025–2026?

Building owners in the four-jurisdiction service area should be aware of several regulatory developments that are relevant as they plan winter and ongoing maintenance:

• In Pennsylvania, a significant regulatory update — Regulation #12-123 — takes effect on December 20, 2026. This update transitions new permit applications to ASME A17.1-2016 and changes how Category 1 tests are scheduled. Building owners planning any repairs, alterations, or modernizations should coordinate with their elevator service provider to understand whether the work falls before or after the December 20, 2026 effective date, as the applicable code edition differs.
• In Maryland, the Maryland Department of Labor adopted ASME A17.1/CSA B44-2022 (with Maryland changes), effective June 17, 2026. Owners and contractors should confirm that any work performed references the correct code edition based on when the installation contract was signed.
• In the District of Columbia, DOB has indicated plans to adopt construction codes based on the 2024 model codes by the end of 2027. While this does not create an immediate 2026 deadline, building owners planning future modernizations should factor this anticipated transition into long-range capital planning.
• In Virginia, the 2021 USBC incorporating ASME A17.1/CSA B44-2019 has been in effect since January 18, 2024. Annual periodic inspections remain the standard requirement, with local jurisdictions retaining the authority to require six-month inspections.

What Should I Do If My Elevator Breaks Down During a Winter Storm?

1. Do not attempt to restore service without a qualified technician. Resetting a tripped safety device or overriding a fault condition without understanding its cause can create unsafe conditions.
2. If a passenger is trapped, call emergency services immediately. Do not attempt to manually open doors or extract a passenger without trained assistance. Communicate with the entrapped person through the two-way communication system to reassure them and gather information about their condition.
3. Contact your elevator service provider’s emergency line. Most elevator service agreements include provisions for emergency response. Have your elevator identification number, building address, and a description of the fault ready when you call.
4. Post signage at all elevator landings indicating that the elevator is out of service and directing occupants to stairways. In DC, building operators are required to keep at least one elevator operational in occupied buildings with passenger elevators where multiple elevators are available.
5. Document the incident. Note the date, time, conditions, fault codes displayed, and any actions taken. In Pennsylvania, owners must submit an accident report to the Department of Labor and Industry when an elevator accident causes a fatality or requires professional medical care. Maryland and DC have similar reporting obligations for serious incidents.
6. Do not return the elevator to service until a qualified technician has identified and corrected the cause of the failure, and any required notification to the applicable regulatory agency has been made.

How Does Winter Weather Affect ADA Compliance for Elevators?

The Americans with Disabilities Act (ADA) requires that accessible routes — including elevators — remain operational in facilities covered by the Act. A winter equipment failure that takes an elevator out of service may constitute an ADA compliance issue if the elevator is part of the required accessible route and no accessible alternative exists.

Building owners should recognize that ADA obligations do not pause for weather events. Proactive winter maintenance that keeps elevators operational is therefore both a safety practice and an accessibility compliance strategy. When an elevator must be taken out of service for winter repairs, building owners should immediately evaluate whether temporary accessible alternatives can be provided and consult with legal counsel if the situation is complex.

What Industry Trends Are Shaping Elevator Winter Maintenance in 2025–2026?

Several qualitative trends are shaping how building owners and elevator service providers approach cold-weather preparedness in the DC, Maryland, Pennsylvania, and Virginia market:

Remote monitoring adoption is growing. More elevator systems — particularly those that have undergone recent modernization — are being connected to remote monitoring platforms that track temperature in machine rooms, detect control faults in real time, and alert service providers before a complete breakdown occurs. This trend is particularly valuable in winter, when temperature fluctuations can cause intermittent faults that are difficult to diagnose after the fact.

Hydraulic fluid technology is evolving. Manufacturers are offering biodegradable and synthetic hydraulic fluids with wider operating temperature ranges. For older hydraulic systems in the Mid-Atlantic region — where winter temperatures can shift rapidly — upgrading to a more thermally stable fluid is an option worth discussing with a qualified service provider.

Code modernization is increasing performance expectations. As Maryland transitions to ASME A17.1-2022 and Pennsylvania prepares for ASME A17.1-2016 adoption in December 2026, the technical requirements for elevator safety systems are becoming more comprehensive. Building owners investing in winter preparation and modernization are well-positioned to meet upcoming compliance requirements proactively rather than reactively.

Energy efficiency and sustainability considerations are influencing machine room heating and insulation decisions. Building owners increasingly recognize that a well-insulated, efficiently heated machine room reduces both winter elevator failure risk and long-term energy costs.

How Often Should Elevators Be Serviced During Winter?

Maintenance frequency during winter depends on equipment type, age, building occupancy pattern, and local climate conditions. Jurisdictional requirements establish minimum inspection intervals — annual in Virginia and Maryland, up to every six months for electric and hydraulic elevators in Pennsylvania — but these are floors, not ceilings.

For older equipment, hydraulic systems, or elevators in buildings with unheated or poorly insulated machine rooms, more frequent service visits during the winter months are a sound investment. A mid-winter check — particularly after the first sustained freeze of the season — allows a technician to identify any degradation in lubrication, fluid condition, or electrical components before it becomes a service disruption.

Quality Elevator Company works with building owners across DC, Maryland, Pennsylvania, and Virginia to establish maintenance schedules that reflect the actual risk profile of their equipment and building conditions, not just the regulatory minimum.

Does OSHA Have Any Requirements Relevant to Elevator Winter Safety?

The Occupational Safety and Health Administration (OSHA) establishes requirements relevant to elevator work performed by technicians, including those working in cold or adverse conditions. Employers are responsible for ensuring that workers performing elevator maintenance, inspection, or repair in winter conditions — including cold machine rooms, icy pit access areas, or exterior-facing equipment — have appropriate personal protective equipment and are protected from cold stress hazards. Building owners overseeing contractor work should ensure their service providers operate in compliance with applicable OSHA standards.
