In an era marked by rising energy costs and growing concerns about climate change, the efficiency of residential air conditioners and heat pumps has become a pivotal factor in product development.

At UL Solutions, we offer a comprehensive certification path for load-based testing (LBT) that helps manufacturers demonstrate compliance to energy efficiency standards. Your products are tested under real-world conditions, offering meaningful insights that can help build credibility and distinguish you in a competitive marketplace.

The need for innovative testing methods

As air conditioning and heat pump technologies evolve — recent advancements include sophisticated control algorithms and variable-speed components — traditional testing methods can fall short in assessing how systems perform under varying conditions. For instance, legacy standards often rely on static conditions that can fail to reflect how a product performs across a broad range of real-world scenarios.

LBT addresses these gaps, offering a more accurate evaluation of energy efficiency and system performance.

Benefits of our LBT services

LBT offers several advantages, including:

LBT delivers efficiency metrics that are more reflective of real-world usage conditions, providing a more objective view of your product’s energy efficiency.
