Who It's For
Birmingham metro homeowners who just rode out a storm and need to know whether the AC is safe to run.
What's Inside
Pre-restart inspection (8 points), insurance photo checklist, common storm-damage failure modes, what to call before doing, and the 4-week post-storm monitor list.
Why It Matters
Most HVAC problems in Birmingham are preventable or fixable cheaply if you know what to look for. This guide tells you what.
Birmingham storms hit hard. Half the post-storm AC failures aren't obvious in the first 10 minutes. A bent fan blade, water in the disconnect box, lightning damage to the control board — all easy to miss, all able to kill the system within days if you just flip it back on. This checklist makes the difference between a smart restart and a $3,000 mistake.
This is the field-guide version -- the same approach a 25-year HVAC tech takes walking into a service call. No marketing fluff. No upsells dressed up as "tips." Just the working tech's playbook, written down.
A look inside
Don't restart yet
After a storm — thunderstorm, tornado, straight-line winds, hail — the first impulse is to flip the breaker and check that the AC works. Don't. The outdoor unit just took the same beating the rest of your yard did. Five minutes of inspection now saves a week of headaches.
Step 1 — Visual scan of the cabinet
Walk around the outdoor unit. Note:
- Dents in the cabinet (large branch impacts, hail bruising)
- Anything obviously bent (fan grille pushed in, side fins flat)
- Anything missing (top fan grille blown off, side panel gone)
- Position — has the unit shifted off its concrete pad? Is the pad cracked or tilted?
- ...
Step 2 — Coil and fin inspection
The aluminum fins on the outside of the cabinet are fragile. Hail and debris bend them flat.
- Look at the fins from every side
- Any extensive flattening (more than a few square inches) = airflow problem
- Any deep dents to the underlying copper coil = potential refrigerant leak risk
- Photograph the worst areas with a quarter or hand for scale
