ES3: Cooling equipment efficiency

• Ducted Split system ≥14.5 SEER
• Ducted Package unit ≥12 EER 
• Ducted ground-source heat pump(s): ≥15 EER

Purpose

A high-efficiency system will deliver more comfort, better moisture control, improved air quality, and quiet operation, while using less energy than a less efficient system.

Criteria

If installing a split system HVAC unit(s), the cooling equipment must have a seasonal energy efficiency ratio (SEER) of 14.5 or greater. If installing a packaged HVAC unit(s), the cooling equipment must have an energy efficiency ratio (EER) of 12 or greater. If installing a ground source heat pump(s), the energy efficiency ratio (EER) must be 15 or greater.

SEER and EER must be determined by the Air Conditioning, Heating and Refrigeration Institute (AHRI).
