A new study by V-Guard Industries has flagged a major but often overlooked factor behind rising electricity bills—low voltage. The research, validated by a NABL-accredited laboratory, shows that sub-optimal voltage can increase air conditioner power consumption by up to 50%, acting as an “efficiency tax” on households. The study examined multiple 1.5-ton AC units from leading brands and found that when voltage drops to 140V–180V—a common occurrence during peak summers—the compressor’s efficiency declines sharply. This forces the AC to run longer to achieve the same cooling, significantly increasing energy usage. V-Guard Managing Director Mithun K Chittilappilly said many consumers misunderstand…
