Summer Elevator Care: Precautions to Take Before and During the Hot Season

Summers are getting hotter every year, and extreme heat can affect more than just human comfort. Elevators also need special care during the summer season. Elevator systems are designed to work within a particular temperature range. If the machine room, controller area, or lift cabin becomes too hot, it can affect performance, reliability, and passenger safety.

During summer, buildings often face heat waves, dust, dry winds, heavy electrical load, voltage fluctuations, and power cuts. These conditions can put extra stress on elevator components such as the controller, motor, drive system, batteries, door mechanism, cabin fan, emergency light, alarm, and intercom.

For residential societies, commercial buildings, hospitals, hotels, offices, malls, and industrial properties, pre-summer elevator maintenance is important. A timely inspection can help prevent sudden breakdowns, reduce repair costs, and improve passenger comfort.

At Blue Star Elevators, we recommend that building owners and property managers complete a proper elevator check-up before peak summer begins.

Why Elevators Need Special Care During Summer

During summer, elevators may face issues due to:

• High temperature in the machine room or controller area
• Heating of the elevator controller and electrical panels
• Poor ventilation around elevator equipment
• Power cuts and voltage fluctuations
• Weak battery backup due to heat
• Cabin fan or cabin ventilation problems
• Dust entering lift door tracks and lobby areas
• Burning smell or electrical faults due to overheating
• Sudden shutdowns or repeated tripping
• Passenger discomfort inside the lift cabin

Elevator usage may increase in some buildings during summer, while in others it may remain normal. However, even regular elevator usage can put more stress on the system when the surrounding temperature is very high.

That is why preventive care before and during summer is very important.

Precautions to Take Before the Summer Starts

1. Schedule a Pre-Summer Elevator Inspection

Before peak summer, building owners and property managers should schedule a professional elevator inspection with the authorized elevator service team.

A pre-summer inspection helps check:

• Machine room or controller area ventilation
• Controller heating issues
• Motor and brake condition
• Cabin fan and ventilation
• Emergency alarm, intercom, and light
• ARD and battery backup, if installed
• Door tracks and door movement
• Power supply and generator backup
• Dust buildup near elevator equipment
• Any signs of overheating or burning smell

This inspection should be treated as a seasonal safety check, not just a routine service.

2. Keep the Machine Room or Controller Area Cool and Ventilated

The machine room or controller area is one of the most important places to check during summer. In many buildings, the machine room is located on the terrace or top floor, where temperatures can rise significantly during the day.

If this area becomes too hot, it can affect the elevator controller, drive system, motor, brake system, batteries, and other electrical components.

Property managers should ensure that:

• The machine room has proper ventilation
• Exhaust fans or ventilation fans are working
• Air vents are not blocked
• The room is clean and dust-free
• The machine room is not used for storage
• The door remains locked and accessible only to authorized persons
• No flammable items are kept near elevator equipment

For machine-room-less elevators, the controller cabinet or control panel area should also be kept clean, dry, and properly ventilated.

3. Consider Machine Room Air-Conditioning if Required

In some buildings, normal ventilation may not be enough. If the machine room remains extremely hot, especially during afternoon hours, air-conditioning or a dedicated cooling arrangement may be required.

This may be needed when:

• The machine room is on the terrace
• The room receives direct sunlight
• Natural ventilation is poor
• The lift has frequent heat-related shutdowns
• The controller or drive panel becomes hot
• The elevator is critical for hospitals, offices, hotels, or high-rise buildings

Machine room air-conditioning should be planned properly after consulting the elevator service provider or a qualified professional. Cooling arrangements should be safe for electrical equipment, and condensation or water drainage should not create any risk near panels.

Avoid unsafe temporary methods such as placing water coolers, wet cloths, or loose temporary wiring near elevator equipment.

4. Prevent Controller and Component Overheating

The elevator controller is like the brain of the elevator. It controls movement, door operation, speed, leveling, and safety functions. If the controller overheats, the elevator may stop suddenly, trip repeatedly, show faults, or operate irregularly.

Some elevator components also naturally produce heat during operation. For example, in certain elevator systems, a braking resistor or braking resistance unit may become hot when the elevator slows down or stops. This is normal to some extent, but the heat must be able to escape safely.

Building owners and property managers should ensure:

• Controller areas are not blocked
• Heat-producing components have enough space
• Ventilation fans are working
• No cardboard, plastic, paint, chemicals, or scrap is stored nearby
• Burning smell, excessive heat, or repeated shutdowns are reported immediately

No one should touch or try to cool elevator components manually. Some parts can remain hot even after the elevator stops. Always call the elevator service provider for inspection.

5. Check Cabin Fan, Ventilation, and Cabin AC Options

Passenger comfort is very important during summer. A lift cabin can become uncomfortable if the cabin fan or ventilation is not working properly.

Before summer, check that:

• Cabin fan is working
• Ventilation openings are not blocked
• Cabin lights are working properly
• Emergency light is working
• Alarm and intercom are functional
• The cabin is clean and well-maintained

Many modern elevators also offer car cabin air-conditioning. Cabin AC can be useful in premium residential buildings, hospitals, hotels, commercial buildings, glass elevators, and buildings where passenger comfort is a priority.

If the elevator already has cabin AC, it should be serviced before summer. The cooling performance, filters, electrical connection, drainage or condensation arrangement, and power load should be checked by qualified personnel.

If a building wants to install cabin AC in an existing elevator, it should be done only after confirming that the elevator design, power supply, and safety requirements allow it.

6. Check Power Supply and Generator Backup

Summer often increases the electrical load in buildings due to air-conditioners, coolers, pumps, and other equipment. This can lead to voltage fluctuations, low voltage, phase failure, and power cuts.

Elevators need stable power. Poor power conditions can affect the controller, motor, drive system, door operator, and emergency systems.

Building management should ensure:

• Proper power supply to the elevator
• Proper earthing
• Voltage protection where required
• Generator backup is suitable for elevator operation
• Changeover system is working properly
• Electrical panels are not overheating

If the building uses generator backup, test elevator operation before peak summer. The lift should run smoothly on backup power without jerks, sudden stops, or repeated faults.

7. Test ARD, Battery Backup, Alarm, and Intercom

Power cuts are common during summer. If the elevator stops due to power failure, emergency systems must work properly.

Before summer, test:

• Automatic Rescue Device, if installed
• Emergency alarm button
• Intercom or communication system
• Emergency light inside the cabin
• Battery backup
• Manual rescue arrangement
• Emergency contact display

Heat can reduce battery life. Batteries that worked well earlier may become weak during extreme temperatures. Weak batteries can affect ARD operation, emergency lights, alarm systems, and communication systems.

This is especially important for high-rise buildings, hospitals, senior citizen residences, hotels, malls, and buildings with frequent power cuts.

8. Keep Lift Door Tracks and Lobbies Clean

Summer dust and dry winds can affect lift doors. Dust, small stones, paper, and debris can collect in door tracks and cause door problems.

Common door-related issues include:

• Doors not closing properly
• Doors reopening repeatedly
• Slow door movement
• Door noise
• Lift not starting because the door is not locked properly

Housekeeping teams should:

• Clean lift lobbies regularly
• Avoid sweeping dust into door tracks
• Keep mats away from the lift sill
• Remove debris near lift entrances
• Avoid excessive water cleaning near lift doors
• Keep lift entrances clear

Clean door tracks help the elevator operate smoothly and reduce unnecessary complaints.

9. Do Not Use the Machine Room as a Storage Area

The machine room or controller area should never be used for storage.

Avoid storing:

• Old furniture
• Paint containers
• Cleaning chemicals
• Scrap material
• Construction items
• Cardboard boxes
• Plastic items
• Flammable material

Storage blocks ventilation, increases heat, creates fire risk, and makes maintenance difficult. The machine room should remain clean, locked, ventilated, and accessible only to authorized persons.

10. Special Note for Hydraulic Elevators

Some buildings have hydraulic elevators. In hot weather, hydraulic oil temperature can affect performance. If the oil becomes too hot, the elevator may show slow movement, leveling issues, jerks, or shutdowns.

Building owners do not need to check this themselves, but they should ask the elevator service provider to inspect the hydraulic system before peak summer.

Elevator Care During the Summer

1. Monitor Warning Signs

During summer, do not ignore small signs of elevator trouble. Call the elevator service provider if you notice:

• Burning smell
• Lift stopping suddenly
• Lift stopping between floors
• Jerky movement
• Doors reopening repeatedly
• Cabin fan not working
• Emergency light not working
• Alarm or intercom not working
• Repeated electrical tripping
• Unusual noise from machine room
• Lift faults during hot hours

Early reporting can prevent major breakdowns and reduce downtime.

2. Respond Properly During Power Cuts

If the lift stops during a power failure, passengers may become worried, especially in hot weather.

Users should:

• Stay calm
• Use the alarm or intercom
• Never force open the lift doors
• Never try to climb out
• Wait for trained rescue support

Property managers should ensure emergency contact numbers are displayed near the lift and with the security or building management team. Manual rescue should be done only by trained and authorized persons.

3. Do Not Restart the Elevator Repeatedly After a Fault

If the elevator stops repeatedly, trips frequently, or shows signs of overheating, do not keep restarting it again and again.

In such cases:

• Stop using the elevator
• Inform the building manager or security team
• Contact the elevator service provider
• Do not open the controller panel
• Do not allow unauthorized repairs

Repeated restarting can worsen the problem and damage expensive components.

4. Avoid Overloading and Misuse

Overloading is unsafe in every season. During summer, it can create additional stress on the motor, brake, controller, and power system.

Users should:

• Follow the passenger capacity displayed inside the lift
• Avoid carrying heavy goods in passenger lifts
• Use service lifts for material movement, where available
• Avoid forcing extra people into the lift
• Never block doors with hands, bags, or objects
• Keep children from playing inside the lift

Responsible use helps keep the elevator safe and reliable.
