American Home Shield AHS Refused to cover a new A/C compressor Ventura California

So after paying 16 years of premiums from when my house was brand new, my A/C compressor developed a leak and now AHS is refusiing to cover it saying the yard sprinklers caused damage to the unit. They sent 2 companies with incompetent technitians who I showed the sprinklers do not hit the unit but they said the units are outside and next to the yard and so they are using the sprinklers as an excuse. Well show me an outside A/C compressor that is not near a lawn and subject to environmental moisture. Total ripp off of my premiums.
