I have been a AHS customer for years with very few service calls. However, over the past year or so, I noticed the quality of subcontractors AHS send to the home have been horrendous (missing appointments, habitually latem, poor customer service, and overcharging). One of the last services I had was for my A/C. The subcontractor who AHS hired showed up late then tried to run up costs for an appropriate repair (this was for an HVAC in a home that was less than 5 years old). In the end, it turned out to be a simple $150.00 repair. Because I complained about the quality of subcontractors and challenged the subcontractor that came to my home, AHS sent me a letter to explain they would no longer renew my contract after the current policy period. I called repeatedly to Customer Service and even spoke with the corporate office to ask why they would not allow me to renew my contract. I was repeatedly lied to and told that their costs for repairs outweighed my policy costs. I challenged their reasoning since in the last 7+ years, I have paid them over $10,000 on 3 homes and had no more than $1,000 to $2,000 of repairs (in total for all 3 homes). Each time I offered my numbers they explained that they would have someone review and get back to me. No one ever did and when I kept calling back, they sent me another letter explaining my contract would not be renewed and again, provided no explanation. Instead of appreciating a customer contacting them when the subcontractors they hire (by the way, all of whom, over the past year or so, had poor ratings by several online rating sites) try to rip off customers or waste customers time by not showing up, AHS dumps the customer. The below Cost of service was the average annual cost for the premium I paid for 3 homes (an amount I paid in full every year for several years).
