As the world grows hotter, air conditioning units need to meet a growing demand to require less energy to operate.
A growing number of startups are launching new products that are greener and more efficient.
Highly efficient ACs can help ease strain on the electric grid and help it withstand sizzling temperatures.
Among leading new companies are Blue Frontier, Transaera and Montana Technologies, with most new units focusing on the humidity control rather than the heat, using new materials like liquid salt to dry out the air.
The startups are rushing to capitalize on a wave of government regulation and incentives such as tax credits and rebates for high-efficiency products that are part of the U.S. Inflation Reduction Act.
