Piedmont Mechanical Contactors Inc

My furnace was making a loud noise and I have a home warranty through AHS so I called and paid the deductible to have someone come out to take a look. They dispatched to this company. It took three days for the company to actually respond to the dispatch. Then, the tech arrives, shuts off my entire HVAC system, and leaves telling they "need to get a part." I call the next morning to find out what is going on and I'm told they need to order a part and it will be 3-5 business days. I ask to have my system, which was working, turned back on but they can't. Six days go by and I have heard nothing so I call again. The tech is on Jury duty for the next 2-3 days, they have no idea if he's ordered the part, they have no way to get in touch with him, they don't know if or when the part will arrive or when he can come install it. And they still can't turn on the furnace or A/C even though it was working when they arrived, albeit noisily. All the secretary can tell me is, "I don't know." Do not go anywhere near these people. They have close to 50 one star reviews complaining about how terrible they are.
