Woke up to no heat in house. Furnace not working, blinking red light on it. Action Furnace came out, told me control board is shot, inducer motor is seized, pressure switches need replacing, and heat exchanger has burn marks on it, needs replacing. Total cost......$4,000. Or they can sell me new one for $4,500. So I got a second opinion. Turns out control board was faulty, and was not giving inducer motor the 120V it needs. Inspection on rest of furnace showed it was fine. Total cost of fix, done on the spot, $800. Had I not gotten a second opinion, I would have spent an extra $3,000. Dishonest. Not ok.
