HVAC Checks After a Tornado or Severe Storm in Southern Kentucky

Safety first, before any inspection

Severe weather is a reality here — the May 16, 2025 tornado crossed the south side of Somerset and reached EF4 strength in London, destroying homes and taking lives, and many families are still rebuilding. We write this plainly and practically, because the goal is to keep you safe, not to sell on fear. If your HVAC equipment is near a downed power line, standing water, or structural damage, stay away from it and let professionals make it safe first.

Never restore power to an outdoor unit or furnace that has been submerged or stood in floodwater. Water in the electrical components and motor windings makes energizing the unit dangerous. If you smell gas after a storm, leave and call the gas company from outside.

What storm damage to HVAC actually looks like

Some damage is obvious; much of it is not. Look for:

• An outdoor unit shifted off its pad, tilted, or moved by wind
• Debris, branches, gravel or siding driven into the coil and fins
• Bent or flattened coil fins restricting airflow
• Torn, exposed or pulled refrigerant lines and electrical whips
• A water line or mud line showing how high flooding reached
• A tripped breaker or a unit that is simply dead after the storm

A unit can look fine and still be damaged. That is the trap of storm damage, and it is why a visual once-over is not the same as an inspection.

The invisible threat: power surges

The most common storm damage we find is also the least visible: a power surge. Lightning and the grid disruptions during and after a storm can send a spike through the electrical system that fries a control board, a capacitor, or even the compressor — while the outside of the unit looks completely normal. The homeowner flips it on days later, it does nothing or trips the breaker, and the storm connection is not obvious.

If your area took lightning or lost power during a storm and the HVAC has not worked right since, a surge is a prime suspect. A technician can test the board, the capacitor, and the compressor to find what the surge took out.

Flood and water damage

Floodwater is especially hard on HVAC equipment. It carries silt and debris into coils and motors, corrodes electrical contacts, and leaves moisture where it does not belong. An outdoor unit or furnace that has been submerged generally should not be powered up until it has been inspected, cleaned, dried and tested — and in many cases, significant submersion means replacement rather than repair, because the long-term reliability of water-damaged electronics and motors is poor.

For a furnace or air handler that took water, the safety stakes are higher still: compromised gas controls and electrical components are not something to gamble on. Have it checked before you trust it.

Documenting damage for an insurance claim

If you intend to file a claim, good documentation matters. A contractor can document the HVAC damage and prepare an insurance-ready estimate — but we are careful and honest about the limits: the insurance company determines coverage, not the contractor, and anyone who promises claim approval or a specific settlement is not being straight with you.

Useful documentation includes the equipment's model and serial numbers, clear photos of the damage and the surrounding conditions, a record of the system's age and condition before the storm, and a line-by-line scope of the needed repair or replacement. We provide that documentation when you need it, and we keep it factual.

When to repair and when to replace

Debris that bent fins or clogged a coil is often repairable. A surge that took out a control board on an otherwise sound, newer unit is usually a repair. But a compressor killed by a surge on an older system, or a unit that stood in floodwater, often tips toward replacement — both for cost and for long-term reliability. We lay out honest repair-versus-replace options and let you decide.
