Over 9 Killed As AC Blasts On Rise In Delhi-NCR: How To Prevent Electrical Fires At Home

Last Updated:June 29, 2026, 14:32 IST

With temperatures soaring, experts warn that prolonged use of ACs can overload ageing electrical systems if they are poorly maintained.

AC Blast: A fire broke out in a flat on the 21st floor of a Noida high rise building on Monday morning. The blaze, which was likely triggered by an air conditioner explosion, was brought under control after nearly 30 minutes.

The blaze broke out around 8:50 am in a flat on the 21st floor of Aranya Society in Sector 119 after an explosion in an air-conditioner unit, according to the fire department. Six fire tenders were rushed to the spot and brought the fire under control within about 30 minutes. No casualties or injuries were reported.

Officials said the family was asleep when the AC unit exploded, but managed to escape safely as firefighters quickly contained the blaze.

“The family was asleep when the AC unit exploded, triggering the fire. The blaze was doused promptly and no casualties or injuries were reported in the incident," Kumar said.

The incident comes weeks after a series of fatal fires linked to suspected AC-related electrical failures. Last month, retired IAS officer and former Competition Commission of India chairman Dhanendra Kumar died in a fire at his Delhi residence following a suspected AC blast. In May, nine people, including a toddler, lost their lives in a devastating fire linked to an AC explosion in Delhi’s Vivek Vihar.

Such incidents have once again highlighted the growing risk of electrical fires during peak summer. With temperatures soaring across several parts of the country, experts warn that prolonged use of air conditioners and other high-power appliances can overload ageing electrical systems if they are poorly maintained.

The Chamber of Trade and Industry (CTI) has also issued an advisory urging people to get air conditioners serviced only by authorised or trained technicians. The traders’ body warned against the use of unauthorised mechanics for gas refilling and repairs, saying improper servicing, electrical faults, overheating compressors and gas leaks can increase the risk of fire.

What Should Be Done To Prevent Fire?

Never Ignore Warning Signs: An AC should never make loud buzzing noises, emit a burning smell, or leak excessively. These are often early warning signs of overheating, compressor failure, wiring issues, or short circuits.

Switch off the AC immediately if you notice: Burning smell, Buzzing or unusual noises, Smoke, Excessive water leakage, Ice formation on the unit or Poor cooling performance.

Many people continue using malfunctioning ACs, assuming it is a minor issue, but electrical faults can escalate quickly. If you notice anything unusual, switch off the appliance immediately and call a certified technician.

Service Your AC Regularly: Dust accumulation, clogged filters, damaged wiring and low refrigerant levels force AC units to work harder, increasing overheating risks.

Experts recommend servicing ACs at least once before peak summer begins. Outdoor units should also be cleaned regularly because blocked airflow can raise internal temperatures and strain the system.

Old ACs that have not been serviced for years may require deeper inspection, especially for worn-out wires and loose electrical connections.

Avoid Overloading Power Sockets And Extension Boards: One of the biggest fire risks in Indian homes is overloaded electrical circuits. High-power appliances such as ACs, microwaves, geysers and refrigerators should ideally have dedicated power points.

Plugging multiple heavy appliances into one extension board or low-quality socket can lead to overheating and sparks. During summer, when electricity consumption spikes, this risk increases further.

If the lights flicker when your AC starts or the plug feels unusually hot, your wiring may already be under stress.

Don’t Leave ACs Running Unattended For Long Hours: Many households keep ACs running continuously overnight or even when rooms are empty. While modern ACs are designed for extended use, leaving malfunctioning units unattended for very long periods can increase fire risks.

Using timer settings, maintaining proper ventilation around the unit, and switching off appliances when not needed can help reduce electrical load and overheating.

Install Smoke Alarms And Keep A Fire Extinguisher At Home: Most Indian homes still do not have basic fire safety equipment. A small smoke alarm can provide crucial early warning during electrical fires, especially at night when people are asleep.

Know What To Do During An Emergency: Turn off the power supply if it is safe to do so, Evacuate immediately if smoke spreads, Contact the fire department without delay and ensure all family members know emergency exit routes.
