We have Turned on our air conditioning to our home for the first time since last summer. The air conditioner would not turn on so we asked an air con repair man out to look at our system. The repairman has advised that the motor has burnt out more than likely due to a storm. we have lodged a claim with our insurer but are unable to provide the date that the burnout occurred as it is unknown (has happened sometime between last summer and now. The insurance company has refused our claim as we cannot prove that burnout was due to a storm nor can we provide the date of the storm. What can we do?
