5 Ways Direct Lightning Can Impact HVAC Systems in Claims

Lightning losses can look extreme, like this condensing unit taken off its pad. Even then, full HVAC system replacements are unlikely.

Less than 1% of HVAC equipment that HVACi assessed last year had verified direct lightning damage as the cause of loss, according to the CCG IQ 2021 Annual Report. While other perils are more likely to have damaged policyholders’ HVAC systems, adjusters still need to take lightning into consideration in claims.

Direct lightning can impact multiple HVAC system components. The scope of damage varies between specific incidents, but lightning damage likely won’t require a claim settlement for a full replacement. Expert damage assessments are essential for more accurate claim resolutions if any of the following HVAC system components have reported lightning damage.

1. Failed Blower Motors

HVAC blower motors are fans with electric motors used to move air through the HVAC system. They are critical components because in cooling mode, blower motors move the air through the evaporator coil while refrigerant absorbs the heat from the air. In heating mode, blower motors create airflow so that heat is transferred to the air to warm a space.

It may be a surprise that direct lightning can affect this component because blower motors are attached to the furnace, which is part of the indoor equipment in a split system. These losses can occur when lightning strikes a chimney or roof and impacts the furnace cabinetry.

Don’t forget: Arc marks and other visible evidence are present to show where the lightning traveled on a property.

The arc mark shows where direct lightning affected HVAC equipment and resulted in damage to the blower motor.

2. Compromised Refrigerant

Refrigerant is essential to any split system. It evolves from gas and liquid states depending on its temperature and pressure and transfers heat to or away from a space. Lightning striking indoor or outdoor HVAC equipment can affect the refrigerant, which would cause the system to malfunction.

Lightning energized the refrigerant circuit and compromised the refrigerant, but the system could still be repaired.

Sometimes HVAC systems will be void of refrigerant after a reported lightning loss. In one claim that reflected a common scenario, the refrigerant circuit was energized with electricity as the result of a lightning strike. The electricity escaped and arced between the refrigerant piping and evaporator coil housing. In turn, the refrigerant circuit was compromised, though all other components measured within optimal range.

It’s critical to note this type of damage may result in a major repair, but even then, a full replacement is unlikely to be necessary. In this claim, the adjuster was advised that the policyholder needed a new condensing unit, evaporator coil, and copper lineset. An HVAC system expert would recommend replacement equipment that is compatible with and meets efficiency standards of the components already in place.

Refrigerant may also be affected by a failed lineset. HVAC evaluations have shown that lightning can blow a hole in the lineset, which connects indoor equipment to the outdoor condensing unit. This compromises the entire refrigerant circuit, requiring repairs.

Don’t forget: R-22 is a frequently used refrigerant type. Though virgin R-22 was banned in 2020, reclaimed R-22 can still be purchased and used in existing equipment.

3. Malfunctioning Control Boards and Other Electric Components

Lightning struck a property and caused a defrost control board, and other components, to malfunction.

Unlike high voltage surge that can only impact electric components, lightning can affect anything in its path. However, electric components are a probable target for lightning damages. Among the susceptible equipment is the defrost control board.

Though there may not be visual evidence, operational testing would prove whether the board has failed. This type of damage would likely result in a minor repair by replacing the defrost control board to return equipment to pre-loss condition.

Other common electronic components that are susceptible to lightning damage include the indoor control board, outdoor control board, and thermostat.

Don’t forget: Before settling for replacement equipment, whether an individual component or a full system, verify that the cost matches market values for the loss location.

4. Damaged Ductwork

As previously shown, lightning can travel through other non-electric items such as chimney flues and linesets. Ductwork is also susceptible to lightning damage and could be the only HVAC component affected.

Ductwork can also sustain direct lightning impacts.

In one assessment, the unit was operational as were all the internal electrical components; however, there were two failed runs of flexible ductwork. The lightning struck the loss location’s roof, and two flexible ductwork runs in the attic were damaged. All other components measured within an optimal range, and the system could be repaired.

Don’t forget: Comprehensive assessments evaluate all HVAC system equipment so that nothing is overlooked.

5. Impacted Furnace and Condensing Unit

Though lightning can affect small, individual components, it can also impact enough equipment to require a replacement furnace or condensing unit. Even then, a full HVAC system replacement is rare unless there are efficiency incompatibilities. It’s important to have equipment evaluated to know the best course of action.

Don’t forget: Objective experts will ensure only the most appropriate repairs or replacements are recommended to return equipment to pre-loss condition.

The HVACi team uses engineering best practices to thoroughly test all HVAC and Refrigeration equipment and provide recommendations for repairs and replacements. We’ll also recommend settlement costs that are in line with market values. Adjusters will receive a comprehensive report with verified cause of loss and scope of damage to reduce the risk of claims leakage.

Lightning Claim Case Study: Three Needs, One Solution

Claims often include multiple items that need people with specialized knowledge to inspect them. The adjuster for the claim described in this case study sought HVACi’s help to determine if a flue pipe and HVAC system were damaged by lightning. When the insured complained of circuit breakers tripping, the adjuster asked the HVACi experts to get help from StrikeCheck team to add an electrical system evaluation to the assessment scope. StrikeCheck’s lightning verification reports added further data to verify the cause of loss and determine the best recommended steps for the policyholder and insured.
