I submitted at $107 ticket for a leaking pipe. It ended up being the water heater which is "covered" by AHS. However, the contractor added an additional $900 for non-covered services i. E. modification to gas line, modification to water line, permit, dielectric union, expansion tank, insulation... none of which were required (excluding the permit). The tank literally needed to be swapped out. The contract company was Proven Professional Construction Services LLC in Apex, NC. After looking at their reviews, 99% of customers that had contact with them through AHS had the same experience. All left 1star reviews and most were dropping AHS because of this.
They know their contractors are terrible and they do not care. You don't but a home warranty so you can pay additional made up fees down the line.
