My Partner Mr Chad Prandi and I have Service America for 5 years and we had in December of 2014 a call in for one of our rental Units with AC issues , the technician came out and reviewed AC and informed us we need to clean the coils off the AC. This is not covered by the service American contract and he advised us this would cost us $800! Keep in mind new coils cost roughly $900. I asked the technician if you checked the Freon he said that Freon is good and we need to do the coils. I did not believe him and called a different company the technician came out filled the AC unit with new Freon and since then the unit is working perfectly fine! It seems to me that serves America tries to sell services which are not covered by the service contract to make additional money.
PS: the repair has cost only $140 I asked to be reimbursed by service America in got declined
