Furnace and a/c tip # 68

Clean you return air grills. A dirty grill can be as bad as a dirty filter. Stopping air flow and over working the furnace motor. Not sure which one is the return. Its the one with brown fuzz and lint stuck to it. Use a vacuum to clean it off. Aaac service heating and air McDonough 7708754113
