AHS is very unreliable, unprofessional and incompetent. I lost more in wages than the cost of repairs because on 5 occasions the contractor would not show up on the scheduled date and time. It took me more than 6 months to fix my heat pump after 3 changes of vendor last year. This year the problem repeated because the previous contractor left the work incomplete and it took a month and half to get it fixed again after change of 2 vendors. AHS keeps assigning incompetent contractors who never maintain schedules with little care for quality service. This business is all about collecting fees and delivering nothing aka PONZI scheme !!STAY AWAY FROM AHS. read full review »
