Homeowners' insurance policies cover AC units in the same manner both your home’s structure and personal property are protected. If the unit is damaged by a covered loss, stolen, or vandalized, you'll most likely receive claims for repairs or replacement. Some common causes of AC unit damage that are equally covered by the homeowners' insurance include lighting, wind, power surges, fire, smoke, fallen trees, vandalism, and theft.
If the AC system is centralized and considered a part of your home’s structure, it’s covered under the dwelling section of your policy with all-risk coverage (i.e. the AC unit is covered against everything except specific hazards listed in the policy, including flooding, earthquake, power failure, and neglect.
Ductless wall-mounted ACs and window air-conditioning units are covered under the personal property coverage section of your policy. When filing a personal property claim, you’ll need to prove that the damage was a result of one of the listed perils.
