I had a brown out so I turned off the air. The power came back on and I came home and turned on the air conditioning and the outside unit is working but the furnace doesn't blow the cold air into the house.. I have checked for frozen lines and there are none. I turn the air off and the fan to on and there is air coming out of the vents inside the house so I turned the air on and then the air quits coming out of the vents. Please help:)
