Getzschman Heating had come on a Saturday to look at our furnace, and found an issue with it. They returned Monday to replace it and install a new AC system. Our main concern had been timeliness and they were able to get the work done efficiently in one day. The techs were very professional. They showed up on time, explained their work, and showed us how to operate the units properly. We have had no issues with their work or the systems. They are under a service warranty in case there are any issues and we need their help. The price we paid was good.
