Annual furnace maintenance and inspection.

Your parents may refer to this service as a cleaning. Yes, we clean any build-up of dirt in your heating equipment. Today, we do so much more. We check the combustion efficiency of your system. We check for carbon dioxide, we measure smoke concentrations by taking a sample of flue gasses. We measure the temperature of the flue gasses to make sure that the heat from the oil flames is not escaping up the chimney.
