What’s one piece of advice you wish you’d received before your first solo system start-up?

In hindsight, which preparation steps—like pre-start checklists or customer walkthroughs—would you emphasize to new technicians?

Check for refrigerant leaks at all connections don’t forget to remove panel at intake air on air handler a before installation and last make sure condensation drain line is clear on an unit replacement

Hello @msoriano3014 that sounds like three really solid pieces of advice as a checklist for newcomers to the field! Let me know if I got this correct:

1. Go through each refrigerant connection and perform a leak test.
2. Remove the intake-air panel from Air Handler A before I start the installation.
3. Flush and double-check the condensation drain line on the new unit to confirm it’s fully clear.

Is there anything else you’d recommend? Again great checklist!
