Toolbox
See it with your eyes. Then we’ll say what it often is.
Twenty gates. Yes, No, or Skip. If confidence hits 90%, we stop and show the finding. This is not a diagnosis and not a dispatch — it is a checklist so you are not guessing in the dark.
Could not load the checklist. Refresh, or book a visit.
Before you start
- This tool is information, not a licensed diagnosis and not emergency service.
- You may skip any check. Do not do anything you cannot do safely from the floor — no panels, no gauges, no roof.
- If you smell gas or burning, or see smoke: leave. Gas: call the utility from outside, then us.
- MyHVAC.GURU is not responsible for injury or equipment damage from DIY work.
Check the box to continue.
