My landlord uses Old Republic (OR) for home warranty purposes (why, I don't know, but that's another story) and my experience to-date has been miserable. I live in Texas where - as I type - the average temp is 95F degrees.
4 days ago the AC unit died. After numerous calls and appeals for 'out-of-network' service, an AC technician showed up and made what, in his words, was a short-term fix. The existing unit is 20 years old, completely shot and needs to be replaced. Old Republic were made aware of this.
4 days later - today - and the AC unit has broken again. It's close to 100F degrees in my house and OR are dragging their feet on authorizing a new AC unit. Nor will they authorize a portable AC unit in the meantime. No doubt one of their 'approved' technicians will show up 5 days from now, say, "yep, it's broken" and disappear for another 5 days before finally showing up with a replacement unit.
They're rubbish. A waste of time, money and oxygen. Stay the hell away.
