My son bent, twisted, glued and taped wires in the heating unit. Whala heat..... For how long, God only knows.......Seems nobody wants to call a heating/ac repairman... I personally think it could be dangerous since my son isn't trained in heating/ac.... a few sparks and the unit started working... shrugs shoulders ....But you know men, they know everything... ANYWAY, the good thing is , we have heat.....
