"We had the pleasure of meeting Corey tonight. He found the leak in our AC. Showed us where it was and what it meant as far as the AC went. He explained in detail the several options we had as far as fixing it or replacing the unit. He even showed us where and what he found. Very polite and professional. The ladies I talked to at the office was also very polite and professional. I highly recommend this company."
