2013 HVAC Changeout Information

The 2013 Building Energy Efficiency Standards include a number of HVAC-related installation measures that require HERS Rater verification. These include correct refrigerant charge, adequate cooling coil airflow, maximum air handler fan watt draw, and the installation of temperature measurement access holes and saturation temperature measurement sensors. Many of these requirements are climate zone dependent, so please refer to the Building Energy Efficiency Standards (and the documents below) to determine applicability.
