The heat is on, and AC fires are back in various parts of India. Several tragic incidents in recent weeks were being blamed on short circuits in the air conditioning (AC). AC blasts and fires are not uncommon in India during the summer months. Several such incidents have brought attention to the importance of preventing AC blasts are fires.&nbsp; Here is what you should know about AC blasts and fires, and how to prevent them from happening. &nbsp;<h2>What are the causes of AC blasts and fires? &nbsp;</h2>Particularly during intense heat, continuous use of ACs can lead to blasts and fires. These are otherwise rare, but can lead to serious incidents. Poor upkeep and maintenance and lack of proper installation of the ACs may be other causes.&nbsp; &nbsp;AC blasts usually result from electrical faults and short circuits, or leaks in the refrigerant gas components.&nbsp;&nbsp;Some refrigerents gases are flamable. Refrigerants are hydrofluorocarbons (HFC) named R-32, R-410A, R-134A and so on. R-410A is a blend of refrigerants, while R-32 is a single-component refrigerant.&nbsp;<h2>Electrical issues causing AC blasts &nbsp;</h2>Overloading of circuits, faults in wiring, and continued use of damaged components like capacitors can cause sparks in the ACs, leading to blasts and fires. &nbsp;Sparks and flames can ignite parts of the AC, particularly the flammable refrigerant gases.&nbsp;ACs should be properly checked for overheating. This happens because of clogged filters, blocking of AC vents, or overload on the compressor components.<h2>What you should check in your AC &nbsp;</h2>It is a good idea to carry out proper maintenance of ACs ahead of the hot season. Check if your AC units are installed properly. Are there any loose connections? Are there any parts that are substandard? Do you live in a place that is prone to power surges? Have you checked for any manufacturing defects in compressors, fans or other parts?&nbsp;<h2>Prevention of AC blasts and fire</h2> Prevention starts at the AC installation itself. &nbsp;Make sure that your AC is installed by a certified professional. Ask at the installation stage itself if electrical connections are secure and if safety standards have been followed. While it is essential to do an overall maintenance of your AC at least once a year, try to clean or replace filters at least once in three months if possible.&nbsp;This will help prevent the buildup of dust and straining of the AC.&nbsp;<h2>Things to check during annual maintenance &nbsp;</h2>During annual maintenance, take special care to inspect wiring, refrigerant levels as well as wear and tear of various components.&nbsp; &nbsp;Do not plug more than one high-power appliance like AC into the same electrical outlets.&nbsp;Ideally, you should use a dedicated power circuit for each unit of AC to minimise risk of power surge and short circuit. If possible, install surge protectors and stabilisers to safeguard against voltage spikes.&nbsp;<h2>Ventilation for the outdoor unit &nbsp;</h2>If you are using a split AC, make sure that the outdoor unit has proper ventilation to prevent overheating. Clean the outdoor unit periodically and make sure it is free from debris like leaves, dirt or bird excreta.&nbsp;&nbsp;Buy AC units that have non-flammable or low-flammabe refrigerants. It is a good idea to make sure leak detection systems are in place for units using flammable refrigerants.&nbsp; &nbsp;<h2>Do not ignore AC warning signs &nbsp;</h2>Foul smells and unusual noises are typical warning signs that your AC needs checking. Another red flag is frequent tripping of circuit breakers. In case such things happen, immediately turn off your AC and seek maintenance.&nbsp;If possible, install smoke detectors near your AC unit. &nbsp;Keep a fire extinguisher rated for electrical fires handy nearby. &nbsp;&nbsp;<h2>Try not to run AC throughout the night &nbsp;</h2>AC blasts typically happen when people are asleep, and because the AC has been running continuously for hours.&nbsp; While it may not be entirely possible during hot summers, it is a good idea to give breaks to the&nbsp; AC to prevent overheating.<h2>Better safe than sorry</h2> If you are retrofitting an older AC, make sure it meets current safety standards. Outdated units can prove to be costly. Educate members of your household, particularly children, on safe use and operation of AC and its remote controls.&nbsp;Do not tamper with your AC or attempt DIY repairs.&nbsp;Always go for professional installation, routine maintenance, electrical safety, and vigilance for warning signs. &nbsp;

Can your AC cause a blast in your home during intense heat? How to prevent air conditioner fires and explosions

India is set to introduce a new rule that will restrict air conditioners from cooling below 20°C or heating beyond 28°C, according to Union Minister Manohar Lal Khattar. The move is part of a larger push to promote energy efficiency and reduce electricity consumption.“A new provision is being implemented soon regarding air conditioning standards. The temperature standardisation for ACs will be set between 20°C to 28°C, which means we will not be able to cool below 20°C or heat above 28°C,” said Khattar.“We have decided the minimum temperature of ACs will be fixed at 20 degrees Celsius and maximum at 28 degrees Celsius,” he added.This development comes as India's Meteorological Department has issued an orange alert over a heatwave in India's capital Delhi for the next two days amid residents dealing with unbearably high temperatures in the city, with a 'feels-like' temperature reportedly close to 50 degrees Celsius.<h2>What does it mean for AC users?</h2>Once these changes come into effect, air conditioners across India will have a restricted operating range. ACs that currently cool to as low as 16°C or 18°C will no longer be able to do so. The minimum cooling setting will be fixed at 20°C, and heating will be capped at 28°C.This is expected to affect both household and commercial air conditioner use, with authorities set to monitor implementation and impact.<h2>Why the government is making this change?</h2>India faces heavy power demand during peak summer months. By setting a temperature cap on ACs, the government aims to reduce the burden on the national power grid and encourage responsible energy use.Many users often set their ACs to very low temperatures, below 20°C, which leads to unnecessary power consumption. The new rule hopes to address this pattern.<h2>How does raising the AC temperature help save electricity?</h2>According to the Bureau of Energy Efficiency (BEE), setting the AC temperature a few degrees higher can make a big difference. Most ACs in India are set between 20–21°C, but the ideal comfort range is considered to be 24–25°C.BEE says increasing the temperature setting from 20°C to 24°C can result in up to 24% electricity savings. Each 1°C increase can help save about 6% in power&nbsp;consumption.
