Vicinity of Cobblestone Lane in Lincolnton
Last night the outside unit fan stopped working and will no longer kick on when you turn on the thermostat. The inside unit does kick on though, it's just the outside which keeps it from blowing cool air. My fiance only gets paid on Fridays and we have a young child in the house. Do you offer free service estimates and possibly billing options? We are hoping to avoid going all week with no air. Thank you for your time.
