Artificial intelligence, or AI, is now able to handle many of an HVAC contractor’s administrative tasks, and also help employees perform their own tasks better.

The first phase took effect on January 1, 2018, and increased the minimum efficiency of commercial rooftop units (RTUs) by about 13 percent.

Artificial intelligence (AI) is one of the most promising — and exciting — technologies to come to the HVACR industry in a long time.

Commercial rooftop units feature a host of intelligent solutions to improve efficiency and ease of service/installation.

The second phase will take place on Jan. 1, 2023, and require an additional 15% increase in efficiency.

For many manufacturers, higher efficiency systems have been in the works for a while, but the 2023 DOE standards, pandemic, and current supply chain issues have added pressure.

While new DOE standards drive innovation and opportunity within the HVAC industry, they also add pressure and complexity for manufacturers.
