Chad from Allied came out to my house for an emergency on call because my heat kept on turning off and I had to reset it. He called me back within minutes of calling the after hours line. He said he could be at my house with 30 MINUTES but he was at my house within 15 minutes. Chad is very professional, knowledgeable and very prompt. I was very shocked to find out I wouldn't be charged more since it was after regular working hours. I was glad to find out they don't charge extra until after 8pm. Chad quickly troubleshooted the reason my furnace kept shutting down. I highly recommend Allied Services, Inc. and will always use them for my heating and cooling.
