Never had any issues and have always had very good, efficient, friendly technicians. It starts with Amanda in the office. For example, she called me to say we were due a Spring check up and was looking for a day / time to come out. I said my only problem was that I might be out walking our dog. So she said, "No problem, I will call when they are en route". And she did. The technician was very professional, told me what he was doing and got on with it. System is working fine.

Another example, our system is not that old (also installed by R&S) and when a part on the furnace had a warranty issue and needed replacing, they were again prompt and efficient and all at no charge.
