The ENERGY STAR Verified HVAC Installation (ESVI) program helps homeowners identify contractors who install heating, ventilation and air conditioning (HVAC) equipment using the ESVI guidelines. ESVI guidelines are based on the Air Conditioning Contractors of America's (ACCA) HVAC Quality Installation Standards, and are recognized as an American National Standard. These industry best practices help ensure that your new HVAC equipment is:
- Correctly sized to meet your home's needs
- Connected to a well-sealed duct system
- Operating with sufficient airflow in the system
- Installed with the proper amount of refrigerant
When new heating and cooling equipment is installed according to ESVI guidelines, you avoid common installation problems that can reduce the efficiency of your home and possibly shorten the equipment’s life. Improper HVAC installation can reduce your HVAC system’s efficiency by as much as 30%. More information on the ESVI program.
