well, whats worse than a $500 electric bill? a furnace needing sequencers for the electric back-up heat to the heat pump. this problem arose today. the smell of a burnt sequencer (whatever that is) was preferable to the repairmans fragrance when he showed up. and talk about a waste of electricity. he turned the heat up so high while he was working on it (and it was 65 degrees today)i was worked, lemme tell ya....
