I have been using Miller's Heating & Air for over three years now, and everything has been great! I have a service contract with them, and they have been working with me on making sure my old furnace kept running. It finally went out last week so I called them up to have a new one put in. They got me scheduled in at a pretty good time, and they showed up when they said they would and got the job done. The installers were very professional and they were mindful to either take their shoes off or have those coverings on. They also wore masks and cleaned everything up when they were done. There was a problem at first when the original bid for the work was different from the end result because they had to do more work, but it all worked out in the end and they did everything for the original bid amount. I will definitely continue using their services.
