Inspector did not test or VISUALLY inspect A/C unit. His report said because exterior temp was too cold, it was 67. We closed on the house to find the 3 year old A/C unit had a rat chewing wires inside it! A simple visual inspection could have discovered this. They probably didn't look at the unit at all otherwise they would have noticed the rat droppings. Since it is a pre-existing condition our home warranty won't cover it! They failed to inspect one of the most critical items in a home in AZ! Very disappointed and would not recommend. Also, lesson learned. be present while they are inspecting.
