Heat Pump and Air Conditioner Efficiency Ratings: Why Metrics Matter
This white paper examines efficiency metrics (ratings) for residential and small commercial heat pumps and explores the potential benefits and impacts of improving those metrics. It presents evidence that existing metrics are not reliable, particularly for modern, variable-speed heat pumps and air conditioners that are expected to be more efficient, but don’t always live up…
