NEW DELHI: V-Guard Industries has released a new study highlighting how poor power quality significantly impacts energy efficiency, revealing that low voltage conditions can increase air conditioner power consumption by as much as 50%.

The study, validated by a NABL-accredited laboratory, found that when voltage levels drop to between 140V and 180V—common during peak summer months in India—air conditioners operate less efficiently. This forces compressors to run longer to achieve the desired cooling, leading to a sharp rise in electricity usage.

According to Mithun K Chittilappilly, while many modern ACs are marketed as “stabilizer-free,” they are not designed to maintain optimal efficiency under fluctuating voltage conditions. He noted that using a dedicated voltage stabilizer can significantly reduce electricity bills while also protecting the appliance.

The research outlines that low voltage slows down compressor performance, increases cooling time, and leads to higher energy consumption. In some cases, ACs may take two to three times longer to reach the desired temperature, directly inflating power bills.

Beyond higher costs, prolonged exposure to unstable voltage can also damage internal components, especially the compressor, potentially shortening the appliance’s lifespan.

To address these issues, the company recommends the use of advanced voltage stabilizers such as the VWR 400 Plus and VWI 400, which help regulate input voltage and ensure consistent performance.

The findings come at a time when rising energy costs and climate concerns are pushing households to adopt more efficient and sustainable energy practices.
