The first guy came out and complained the whole time. Got up in the attic still complaining maybe to himself but was out loud. Said the my thermostat on the wall was wired the wrong way. Moved one wire over and said it would get me through the winter. Heat still doesn't work. Charged me $203.00. Called again and a second guy comes out stays 7 minutes says my valve on the furnace was bad and it would cost me $500.00 for the part. Then left. Unexceptable!
