We had a reacurring issue with our house's main AC unit...wasn't until our Home Warrenty Company referred us to Tri County did it all get taken care of once and for all. They new exactly what had had happened and were by far the promo test and mist customer service oriented folks we had come out. Most knowledgeable and most curtious....my family is staying cool now and that makes my this 5 Star rating a no brainier!
