Storm Damage Checklist for Facility Managers: HVAC, Plumbing & Electrical
When a facility manager walks into a storm-damaged commercial building, the order of what gets checked first is not a matter of preference. Electrical hazards come first, before HVAC, before plumbing, before anything else, because compromised electrical equipment carries immediate life-safety risk in a way that a damaged rooftop unit or a plumbing leak does not. This checklist walks through the correct sequence for assessing HVAC, plumbing, and electrical systems after a commercial storm event in Indianapolis, in the order that actually protects people first and property second.
Before You Walk In: Safety First
- Do not enter any area with standing water near electrical equipment until a licensed electrician has confirmed it is safe
- Check for downed power lines or visible electrical hazards before approaching the building or affected areas
- Do not assume a building is safe simply because the storm has passed flood water and structural stress can create hazards that are not immediately obvious
- If the main disconnect is not safely accessible, leave power shutoff to a licensed electrician rather than entering water or a hazardous area to reach it personally
When to Call 911 Instead of an Emergency Contractor
Call 911 immediately, before anything else on this checklist, for any active fire, visible electrical arcing, a person in contact with energized equipment or water, structural collapse risk, or a gas odor suggesting a possible leak. These conditions represent immediate life-safety emergencies that take priority over building systems assessment. Once these hazards are addressed or ruled out, an emergency contractor is the correct next call for building systems damage.
Step 1: Electrical System Assessment
Electrical assessment comes first because compromised electrical equipment can appear to function normally while presenting serious fire and shock hazards, a risk profile that HVAC and plumbing damage simply does not share. Industry guidance for flood-affected electrical equipment confirms that submerged panels, breakers, disconnects, and outlets generally require replacement rather than drying and reuse, which is why re-energizing a previously flooded circuit without inspection is a real hazard, not an overcautious formality.
- Identify which panels, outlets, or equipment were submerged or exposed to water
- Confirm power is off to any affected circuit and remains off until inspected
- Check for visible signs of electrical damage: scorch marks, melted components, exposed wiring
- Do not attempt to test or re-energize any water-exposed circuit personally
- Contact a licensed electrician for commercial electrical assessment before proceeding further
Step 2: Address Any Active Water Source
Once electrical hazards are confirmed safe or isolated, the next priority is identifying and stopping any water source still actively contributing to the damage, since continued water intrusion compounds every other problem on this list. Check whether the building’s sump pump system functioned during the event or failed, evaluate whether a plumbing failure such as a burst supply line is still actively leaking, and confirm whether sewer backup is continuing to affect the building.
Step 3: HVAC Equipment Assessment
Ground-level and below-grade HVAC equipment should be checked for water intrusion evidence: watermarks on the cabinet exterior, standing water inside the unit, or visible sediment. Rooftop equipment should be checked for wind damage, including panel displacement, debris impact, and curb or ductwork connection integrity. Any unit with submerged electrical components, motors, or control boards requires professional evaluation before restart, since water intrusion into these components can cause immediate or delayed failure.
Step 4: Remaining Plumbing System Assessment
With the active water source addressed, evaluate the remaining plumbing system: water heaters and other equipment with electrical components that may have been submerged, backflow prevention devices exposed to flood contamination, and drain or sewer lines that experienced surcharge during the event. This assessment covers components that were affected by the flood but are not actively contributing to ongoing water intrusion.
Step 5: Document Everything for Insurance
Photograph the water line reached in each affected area, document visible damage before cleanup or repair begins, note the approximate event timeline, and record any immediate actions taken such as shutting off power or water sources. This documentation should occur before repairs start and before damaged materials are removed, since it establishes the pre-repair condition that insurance adjusters and contractors both rely on.
What This Checklist Does Not Cover
This checklist addresses building systems, HVAC, plumbing, and electrical, assessed by a licensed mechanical contractor. It does not cover structural drying, moisture extraction from framing and insulation, or mold remediation, which fall under the ANSI/IICRC S500 standard and require a certified water damage restoration specialist, a distinct trade from HVAC, plumbing, and electrical contracting. Many storm recovery projects require both: building systems repair and structural drying working in coordination.

Frequently Asked Questions: Storm Damage Checklist for Facility Managers
What should a facility manager check first after a commercial storm event?
Electrical safety comes first, before anything else. If flooding reached any electrical panel, outlet, or equipment, that circuit should remain off and unentered until a licensed electrician has assessed it. Only after electrical hazards are confirmed safe or isolated should a facility manager proceed to evaluate active plumbing sources contributing to ongoing water intrusion, followed by HVAC equipment assessment.
Why does electrical assessment come before HVAC and plumbing in a storm damage checklist?
Compromised electrical equipment presents an immediate life-safety hazard, specifically fire and shock risk, in a way that a damaged HVAC unit or plumbing leak does not carry the same immediate danger. Water-damaged electrical panels, breakers, and wiring can appear to function normally while presenting serious hazard, which is why the safety-priority sequence starts there before moving to systems where the primary concern is property damage and operational disruption rather than immediate personal safety.
What is the first action when a facility manager arrives at a storm-damaged building?
Before entering any area with standing water or visible electrical damage, confirm the space is safe to enter. This means visually checking for downed power lines or electrical hazards before approaching, and not assuming a building is safe simply because the storm has passed. If there is any uncertainty about electrical safety, wait for a licensed electrician rather than entering to assess conditions personally.
Should a facility manager try to shut off power themselves after storm flooding?
If the main electrical disconnect is accessible without entering standing water or an area of visible electrical hazard, shutting off power to affected circuits is a reasonable precaution. If reaching the disconnect requires entering water or an area with visible damage, this should be left to a licensed electrician rather than attempted personally, since the exact hazard being avoided is contact with compromised electrical equipment.
What should be documented for insurance purposes during a storm damage walkthrough?
Photograph and note the water line reached in each affected area, visible damage to equipment and building materials, the approximate timeline of the event, and any immediate actions taken such as shutting off power or water. This documentation should occur before repairs begin and before damaged materials are removed, since insurance adjusters and contractors both rely on this record to establish pre-repair conditions.
How does a facility manager know when to call 911 versus an emergency contractor after storm damage?
Call 911 immediately for any situation involving active fire, visible electrical arcing, a person in contact with energized equipment or water, structural collapse risk, or gas odor indicating a possible gas leak. Once immediate life-safety hazards are addressed or ruled out, an emergency contractor is the appropriate next call for building systems damage, including flood-affected electrical panels, plumbing failures, and HVAC equipment evaluation.
What HVAC components should be checked after storm damage?
Ground-level and below-grade HVAC equipment should be checked for evidence of water intrusion, including watermarks on the cabinet, standing water inside the unit, or visible debris. Rooftop equipment should be checked for physical wind damage, including panel displacement, debris impact, and curb or ductwork connection integrity. Any HVAC equipment with submerged electrical components requires professional evaluation before being restarted.
What plumbing systems are relevant to a storm damage walkthrough?
Check whether sump pump systems functioned properly or failed during the event, evaluate whether sewer backup occurred at floor drains or fixtures, and assess whether any water heaters, backflow devices, or below-grade plumbing components were exposed to flood water. If sump pump failure contributed to the flooding, this identifies both an immediate repair need and a preventive gap for future storm events.
Can Mission Mechanical respond to multiple storm-damaged systems in a single visit?
Yes. Because Mission Mechanical is licensed across HVAC, plumbing, and electrical work, a single visit can address assessment across all three systems rather than requiring separate contractors and separate scheduling for each trade. This is particularly valuable in a storm damage scenario where the interaction between systems, such as a sump pump failure that led to flooding that then affected an electrical panel, benefits from coordinated evaluation.
What is the correct order for a post-storm building walkthrough?
Confirm the space is safe to enter, assess and isolate electrical hazards first, address any active water source that is still contributing to ongoing intrusion (such as a failed sump pump or active leak), then evaluate HVAC equipment condition, then assess remaining plumbing system condition, and document findings throughout for insurance purposes. This sequence prioritizes immediate safety, then stops ongoing damage, then evaluates remaining systems.
Does this checklist apply to wind damage as well as flooding?
The safety-priority sequence, electrical hazards first, applies regardless of whether the storm produced flooding, wind damage, or both. Wind damage specifically calls for additional attention to rooftop equipment, exterior electrical connections, and structural integrity of the building envelope, alongside the flood-related checks that apply when water intrusion occurred.
What should a facility manager avoid doing after a storm event?
Avoid entering standing water in or near electrical equipment, avoid re-energizing any circuit that was exposed to water without professional inspection first, avoid beginning cleanup or repair before documenting conditions for insurance purposes, and avoid assuming HVAC equipment that appears externally undamaged is safe to restart without evaluation if it was in a flood-affected area.
How quickly should storm damage assessment begin after the event?
Assessment should begin as soon as it is safe to enter the affected area. Delaying assessment does not reduce risk and can allow conditions such as continued water intrusion from a failed sump pump or plumbing failure to compound. Early assessment also produces better documentation for insurance purposes than a delayed walkthrough after some conditions have already changed.
