Air conditioner damaged

[Bryan Bravo]

I was gone last week Tuesday for a work trip. Returned late Friday night. My wife called me to inform me the air conditioning wasn’t working properly on Tuesday night. I had her defrost the unit by switching the unit to fan. Late Thursday she informed me that it still was not working. The landlord sent a technician Friday morning. The technician is saying the coil has holes as if someone would have hit it and made a hole on it. My wife has not even been under the coil. And I wasn’t even home. The landlord is saying we must pay for the inside unit since we caused the damages. What are our rights here? Thank you
