Energy Expert Richard Van Orden: Heating System

Yes even if you have had no problems it is always a good idea to have a technician review your system annually.
The technician should perform a safety check and an efficiency test to make sure that your heating system is ready for another season.
Cleaning the system annually will assure you are running at the maximum efficiency. It will also be a good time to review anything that could be a problem during the winter before it happens.
