I had an American Home Shield warranty call for a leaky shower faucet. The technician blamed the problem on loose connections from the handheld shower (which was a lie) and perform only a superficial fix in order to collect the service fee and get out the door. The technician was also unprepared to accept a credit card payment for the service fee.
The leak returned the next morning -- as worse as it was before. I now have to wait another 24-36 hours for another technician to respond to the service call.
Poor customer service and a lack of professionalism from Union Plumbing has left a bad taste in my mouth. I wouldn't recommend them to my worst enemy!
