I love that they called when they were on their way. They were very thorough and tested the new system after it was installed. They also installed a new gas valve because they saw it wasn't up to code and fixed it. Our old furnace was over 30 years old so the codes had changed since then. They explained the new thermostat and where to change the filter and any cautions to look out for. With our new furnace they also provided two new carbon monoxide detectors which I thought was a caring extra step that they are not legally required to do. Both service men were very nice and respectful of our home using drop cloths and the covers over their shoes. Thanks Columbus Worthington Air.
