[Add new paragraphs before Calculations section]"Performance testing is important for identifying any equipment failures or installation problems. HVAC contractors should conduct their own performance testing, but this does not qualify as third-party testing for the purposes of EQ 4.3.Third-party testing must be performed by a qualified energy rater, Green Rater, or a third-party testing and balancing company. If testing indicates insufficient air flow rates, the HVAC contractor should investigate and fix the problem. Once the problem is fixed, the air flow rates must be re-tested and the requirements of the credit must be met before EQ 4.3 can be awarded."
