We've been using Walker for several years now We wouldn't think of using anyone else. They're always ready to help when we need them even when they're busy. The folks at the office are very nice and call us to remind us when it's time to schedule. They always go above and beyond what they actually have to do. That's why we keep with them and we love the technicians that they've sent out to us. We've had three different guys at our home and every one of them was well-mannered and took their time to do the job right. On the occasion we needed them to come back between regular service they're quick to get out and take care of any issue. We can't thank them enough for all they've done for us.
