We we’re impress with Choate’s responsiveness to our needs, Choate’s was one of two companies opened on Saturday and Sunday for HVAC repair. Juan the customer service rep., was friendly and honest about pricing. Second Mike our technician was timely, we were given a window from 1-6pm for the next day, but Mike showed up exactly at 1pm, he was willing to help, very friendly and knowledgeable on the repair. As a result of his friendliness we decided to sign up for the Choate’s family plan (a regular service offered for a monthly fee of $30) to save money and Mike made the repairs and we are grateful, and Choate’s is now our only call for services, and we recommend Choate’s for area’s families as well.James H., Memphis
