Final answer:
All information, including SEER, manufacturer name and model number, and installation date and location, must be collected for heat pump and central air conditioning units for efficiency, identification, and service purposes.
Step-by-step explanation:
For heat pump and central air conditioning units, the information that must be collected is D) All of the above, which includes the Seasonal Energy Efficiency Ratio (SEER), manufacturer name and model number, and installation date and location. The SEER rating is particularly important as it represents a seasonal average of the Energy Efficiency Ratio (EER), indicating the efficiency of the unit in converting electrical energy into cooling energy. The manufacturer name and model number are crucial for identifying the specific equipment and accessing detailed specifications or service information. The installation date and location are essential for potential warranty claims, maintenance schedules, and understanding the environmental conditions that may affect the unit's performance.
