I was extremely pleased with the service I received, although they could not determine an actual problem they were thorough and courteous and spent almost 3 days checking my system just to absolutely sure they didn't overlook anything and to my surprise, because they could not condemn any one thing, in particular, they did not charge me for their time. I will definitely be returning and recommending them to my relatives and friends. Justino was my service advisor and was a delight to work with and Mike was exceptionally friendly. A definite diamond in the rough and I am glad my friend suggested them to me
