My againg parents called for a winter cleaning and inspection before turning on ther furnace this fall. The service person first said the 10 year old furnace needed new parts, and at at the age of the unit, why bother - just replace it. When my Mother asked a few questions, he tried a new apporach with a carbon monoxide detector, showing that he had a reading, although my parents' detectors have never sounded. With her children's encouragement, she called another company for another opinion. Absolutley nothing wrong with the furnace - no carbon monoxide. At least when she called to complain, the manager quickly refunded her ""inspection fee"".... so quickly infact that it seemed like he has had this complaint a few times before.
