"I've used TDK for a number of years. Their technicians are knowledgeable, professional, and always respectful of my home. They show up when they say they will. They do a very thorough job of servicing my A/C and then inform me of what they have checked and done, including cleaning out mud and debris from the unit after my property was subjected to flooding. I can't imagine using anyone else for A/C service and repair. "
