A Delta T report is important after installing a new air conditioner because it helps assess the system’s efficiency and identify potential problems. Delta T, the temperature difference between the supply and return air, is a key indicator of how well the system is transferring heat and cooling the space. A properly functioning air conditioner should have a Delta T within a specific range, typically 16-22°F. 

Here’s why a Delta T report is important:

• Efficiency Check:

Delta T is a primary metric for evaluating the efficiency of an HVAC system. A Delta T outside the normal range can indicate issues with the system’s performance or operation. 

• Troubleshooting through Delta T:

A low Delta T (less than 16°F) could suggest a problem with the system’s cooling capacity, while a high Delta T (more than 22°F) might indicate a refrigerant charge issue or other mechanical problems. 

• Proactive Maintenance:

Regularly monitoring Delta T can help identify potential issues early on, allowing for proactive maintenance and avoiding costly repairs later. 

• System Optimization:

By analyzing Delta T, HVAC technicians can optimize the system’s settings and operation to ensure peak efficiency and energy savings.
