Criteria for a Quality Heating, Ventilating and Air
Conditioning System
As defined by the California Energy Commission, an HVAC system should:
- Be properly sized to provide correct air flows, and meet room-by-room
calculated heating and cooling loads.
- Be installed so that the static air pressure drop across the air handler
is within manufacturer and design specifications in order to have the
capacity to meet the calculated loads and perform at peak efficiencies.
- Have sealed supply ductwork that will provide proper air flows.
- Have a return system sized to provide proper return air flow.
- Have sealed return ductwork that will provide for proper air flow to the
air handler, and avoid air entering the HVAC system from polluted zones
(e.g., fumes from autos, stored chemicals and attic particulates)
- Have properly sized return air filtration.
- Have balanced air flows between supply and return systems to maintain
neutral or positive pressure in the home.
- Be properly charged with refrigerant.
- Have proper burner operation and proper draft.
