HVAC Installation Procedures
1. Be properly sized to provide correct airflow, and meet room-by-room calculated heating and cooling loads;
2. Be installed so that the static air pressure drop across the handler
is within manufacturer and design specifications to have
the capacity to meet the calculated loads;
3. Have sealed supply ductwork that will provide proper airflow;
4. Be installed with a return system sized to provide the correct return
5. Have sealed return ductwork that will provide proper airflow
5. Have sealed return ductwork that will provide proper air flow
to the fan, and avoid air entering the HVAC system from polluted
zones (e.g., fumes from autos and stored chemicals, and
attic particulates);
6. Have balanced air flows between supply and return systems to
maintain neutral pressure in the home;
7. Minimize duct air temperature gain or loss between the air
handler and room registers, and between return registers and
the air handler;
8. Be properly charged with refrigerant;
9. Have proper burner operation and proper draft.
