Welcome to the State of California


Heating, ventilating and air conditioning (HVAC) system efficiency is important for many reasons. Residential HVAC accounts for nearly 20% of peak electrical use in California. Inefficient HVAC units cause power plants to discharge tons of unnecessary carbon dioxide and sulfur dioxide into the atmosphere each year. Current high efficiency furnaces and air conditioners use up to 50% less energy than those manufactured and installed 20 years ago. Plus, inefficient duct systems leak conditioned air into unconditioned spaces, resulting in higher-than-necessary heating and cooling bills for the homeowner. This section covers system design, ductwork, zoning, air conditioning charge and installation guidelines.
