Storm damage to heating and cooling in Pakenham - and the insurance claim.

Cardinia Shire sits right in the path of the storm cells that run up the Western Port basin and over the Koo Wee Rup plain between October and March. Every year we get the same three calls: hail has chewed the outdoor condenser, a lightning-related outage has taken out the control board, or a burst of damaging northerly wind has lifted an evaporative cooler off its roof kerb. The February 2024 front that pulled power off hundreds of thousands of Victorian homes generated more heating and cooling insurance work for us in a fortnight than the rest of that year combined.

The damage sorts into four categories, and they get treated very differently by an insurer:

• Hail impact: flattened aluminium fins on the condenser coil, cracked fan shroud, punctured coil tube. Visible, obvious, easy to claim - as long as the report separates the hail dents from the pre-existing corrosion.
• Wind: evaporative cooler lifted, roof kerb flashing torn, condenser walked off its pad, line set bent at the flare. Often paired with water entering the roof cavity, which becomes the bigger claim.
• Electrical surge: dead control PCB, welded contactor, blown capacitor, burnt inverter module. Invisible from the outside and the hardest fight with an insurer.
• Water ingress: a breached ceiling penetration or a torn evaporative cooler dumping water into insulation and onto ducts. Wet ductwork loses its R-value permanently and has to be replaced, not dried.

Hail and the condenser coil.

The outdoor coil is a lattice of aluminium fins about 0.1 mm thick pressed onto copper tubes. Hail flattens the fins, and flattened fins stop air passing through the coil. The unit will often still run, which is why people leave it, but the head pressure climbs, the compressor runs hot and the system quietly loses ten to thirty per cent of its capacity. Fin combing recovers some of that on light damage. Anything that has punctured a tube is a coil replacement, because the sealed refrigerant circuit is breached and the charge is gone.

The honest test we apply on a Pakenham hail claim is whether the sealed circuit is breached and how old the unit is. Flattened fins on a three-year-old unit are a repair. The same damage on a fifteen-year-old R410A machine is usually a replacement, because the coil is obsolete, the refrigerant is under phase-down, and the labour to strip and rebuild exceeds the residual value. Most Victorian building policies replace a fixed item new-for-old, so a replacement finding on an old machine is normally the better outcome for you - but only if the report says why.

Surge damage and why insurers argue about it.

This is where most Cardinia claims come unstuck. If the surge came from a lightning strike or from a storm-related fault on the United Energy network, most policies cover it under the lightning or storm peril. If the surge came from an internal fault, a failing capacitor or ordinary supply fluctuation, most policies exclude it as electrical or mechanical breakdown. Those two look identical on a dead board unless somebody documents the difference on the day.

So we photograph the burn pattern on the PCB, log the stored fault codes off the controller before we clear them, and record the date and time of the outage so the insurer can cross-check it against the network operator's own published outage record for your street. That single step wins or loses more Cardinia claims than anything else we do. While we are there we check the switchboard for a surge protection device - under AS/NZS 3000 an SPD is not mandatory on an existing domestic board, but a $250 device on the main switchboard is cheap next to a $1,800 inverter module, and after one surge claim most people fit one.

The six things your insurer needs.

A report missing any of these gets bounced back and adds two weeks to your claim. Make, model and serial number. Install date or a defensible estimate of age. Photographs from three distances - wide shot showing the unit in position, mid shot showing the damaged component, macro shot showing the actual defect. A statement of cause that explicitly separates storm damage from pre-existing wear. Refrigerant charge status with gauge readings if the sealed system is breached. And an itemised repair-versus-replace cost with real model numbers, not a lump sum. We issue all six on one PDF signed by the ARC-licensed technician who actually attended, because an unsigned desktop estimate is the first thing an assessor rejects.

One practical tip. Do not clean up before we get there. People sweep the hail stones away, straighten the fins with a screwdriver and hose the unit down, and in doing so they destroy the evidence that the damage was storm damage rather than age. Photograph it, leave it, and if the unit is unsafe or leaking, ring us for a make-safe rather than touching it yourself.

2026 costs - make-safe, assessment and repair.

Diagnostic call-out with a written insurance assessment is $120-$220, and most insurers reimburse it once the claim is accepted. Condenser coil replacement runs $1,400-$2,600 fitted depending on capacity. Control board or inverter module replacement is $480-$1,800. Compressor replacement on a ducted unit is $2,400-$4,800. A full ducted reverse-cycle replacement where the old unit is a write-off is $11,000-$18,000, and our Pakenham pricing guide itemises the rest.

Worked example from a Cardinia Lakes claim: fourteen-year-old ducted R410A unit, hail-punctured condenser coil, sealed circuit breached and charge lost. Coil obsolete, no parts pathway. We wrote it up as a replacement with photographs and gauge readings, the insurer settled new-for-old on the building policy, and the owner paid only the $750 excess plus $1,900 for a zoning upgrade they chose to add while the roof was open. Total out of pocket $2,650 on a $16,400 job.

Does home insurance cover a hail-damaged air conditioner in Pakenham?

Almost always yes, because hail is a named storm peril on every standard Victorian home and contents policy we have seen. The catch is that a fixed outdoor condenser is usually covered under the building section of the policy, not contents, so if you insure the building and contents with different insurers the claim goes to the building insurer. The other catch is condition: an insurer will pay to repair storm damage, but not to fix a condenser that was already corroded, already leaking refrigerant or already 18 years old and failing. That is exactly why the assessment report matters more than the phone call.

Is a power surge that kills the aircon control board covered by insurance in Cardinia Shire?

It depends on the cause, and this is where most Pakenham claims get argued. If the surge came from a lightning strike or from a storm-related fault on the United Energy network, most policies cover it under the lightning or storm peril. If the surge came from an internal fault, a failed capacitor or normal supply fluctuation, most policies exclude it as electrical or mechanical breakdown. We photograph the burn pattern on the PCB, log the fault codes, and note the date and time of the outage so your insurer can cross-check it against the network operator's own outage record. That single step wins or loses more Cardinia claims than anything else.

What does an insurer need in a heating and cooling damage report?

Six things, and a report missing any of them gets bounced back. The make, model and serial number of the damaged unit. The install date or best estimate of age. Photographs of the damage from three distances - wide shot showing the unit in position, mid shot showing the damaged component, and macro shot showing the actual defect. A statement of cause that separates storm damage from pre-existing wear. The refrigerant charge status with gauge readings if the sealed system is breached. And an itemised repair-versus-replace cost with model numbers. We issue all six on one PDF, signed by the ARC-licensed technician who attended.

Should a storm-damaged ducted system be repaired or replaced on the claim?

The honest test is whether the sealed refrigerant circuit is breached and how old the unit is. A hail-flattened condenser coil on a three-year-old Daikin is a coil replacement, roughly $1,400 to $2,600 fitted, and the insurer will pay to repair. The same damage on a fifteen-year-old R22 or R410A unit is usually a replacement, because the coil is obsolete, the refrigerant is being phased down, and the labour to strip and rebuild exceeds the residual value. Most Victorian policies replace a fixed building item on a new-for-old basis, so a replacement claim on an old unit is often better for you than a repair - but you have to have the report say why.

What does a storm-damage make-safe and insurance assessment cost in Pakenham?

Our diagnostic call-out and written insurance assessment is $120 to $220 in 2026, which includes the gauge readings, the photographs and the signed report. Most insurers reimburse that as part of the claim once it is accepted, and several of the larger ones will pay it directly if you get a claim number before we attend. Emergency make-safe - isolating a damaged outdoor unit, sealing a torn evaporative cooler on the roof, or capping a breached line set so the roof cavity stops taking water - is quoted on the day and is normally covered as an emergency make-safe under the policy without waiting for the assessor.
