24/7 service but they charge an after hours work surcharge? How does that work? Do not sign the release or work order. I think it gives them free reign to charge for everything possible. Such as a cleaning charge after they removed their on equipment. Techs will offer services but were unaware of the cost. I questioned some line items such as the after hours charge as was told if people don't want to pay we can put a lien on your house. All conversation recored as well,so its there. Use them if you have a big wallet.
