Why local businesses use Giles
When the AC quits in a restaurant on a Friday afternoon, you need someone who answers the phone and shows up, not a service ticket. We are small enough that Shane knows every commercial account, and big enough to handle a rooftop replacement. Maintenance customers get priority when it is 95 degrees and everyone is calling.
