Professional and courteous personnel, starting from the salesperson to the servicemen
My furnace was not working and A-1 United Heating and Air replaced it. The fellow that came and did the work was the top of the line; he was conscientious and did a very good job. I thought the people working in the store who were telling about me about the service were very friendly, which drew my attention to the display in the first place. And, the salesperson who came out, looked at things and made an assessment was a very competent professional and helpful.
The two servicemen working together on the installation made sure they cleaned the space after they were done. I liked and appreciated them and that I didn't have to clean up. One of the the young servicemen stood out more to me because he gave the summary on how the furnace works, and also reviewed literature with me. They did a very good job.
