Yesterday Phil Steinberg came to my home in Twinsburg for a service call. At this time, we were told that nothing could be determined as to what was causing the fan of the furnace to run but not heat except that a new furnace would stop this problem from reoccurring. After the problem occurred again overnight, we placed a call with another company. This company immediately inspected the flame sensor needed to be cleaned and pulled. They also found that there was a calcium build up on the igniter as well as a high reading. None of this was even checked by Phil. Hoover Heating and Air Conditioning, clearly knew how to professionally and appropriately solve our problem.
