Real Cooling for a Warming India
India isn’t getting cooler. Summers are getting harsher, heat lasts longer, and cooling is becoming a major energy expense at home. Yet most air conditioners aren’t built for real Indian heat. Optimist exists to change that by building India’s Real AC; delivering best cooling, lowest bills, and designed for tomorrow.
