February 3_NIST Quality HVAC Report ImageA recent National Institute of Standards and Technology (NIST) report proves that HVAC equipment requires a quality installation (QI) in order to perform at its rated efficiency. The report, “Sensitivity Analysis of Installation Faults on Heat Pump Performance,” shows design and installation deficiencies contribute directly to a rise in energy consumption.

The report is based on a three-year study that focused on how the building, equipment and climate affect HVAC performance. The following installation faults were found to have the largest potential impact on efficiency:

  • Duct leakage
  • Low indoor airflow
  • Refrigerant undercharge or overcharge
  • Oversized equipment with undersized ductwork
  • If two or more simultaneous faults occur, the loss of efficiency and amount of energy consumption risk amplification

A QI requires high-efficiency products, correct design, proper installation and accurate field measurements. To help ensure these components are met, the ANSI/ACCA 5 QI Standard specifies what to measure, how to measure and the measurement tolerances necessary for unitary residential and commercial HVAC systems.

We recognized that a successful, sustainable installation not only requires a high-performing product but top-notch service as well, which is why we created the Diamond Dealer™ program more than 10 years ago. This elite group is the most extensive, highly-qualified contractor network in the industry today. Through demanding certification and continuous education, our Diamond Contractors™ ensure that our energy-efficient products perform at their industry-leading efficiencies.
