HVAC systems typically consume the highest percentage of a building’s energy cost. That said, how efficiently do you think the average package unit or split system operate at? If two identical units in the same building are consuming twice as much power and delivering only 50 percent of rated capacity, how apt would you be to address the poor performer?
We’ve found many systems are delivering only 50 percent of their rated capacity into the indoor conditioned space. Combine poor installation and service-related issues with inconsistent maintenance practices or, even worse, a run-to-fail scenario, and we find that many systems operate far below the manufacturer’s Air-Conditioning, Heating, and Refrigeration Institute (AHRI) laboratory rated efficiency.
