Fixing the Furnace

• 1). Think about unusual noises you heard before the furnace died or started acting up. Chattering or a grinding noise can indicate electrical problems. Huffing and puffing noises might indicate delayed ignition issues. Bumps and clunks could indicate a cracked pulley belt. Call a professional to fix these.
  
  
• 2). Check the burners for rust flakes, ash and dirt. These will cause the flame to burn yellow instead of a clean blue. Grit also can cause a flame to flicker or go out.
  
  
• 3). Sweep out and clean the burners.
  
  
• 4). Remove the pilot light and gently blow on it to clean. If this doesn't work, replace the pilot light.
  
  
• 5). Use a fine-grit sandpaper to clean the thermocouple if the pilot light doesn't work. Replace the thermocouple if this doesn't improve the pilot light's performance.
  
  
• 6). Ensure that the blower fan is working properly.
  
  

Insulating Your Home

• 1). Install double-paned windows. The air trapped between the two panes serves as an insulator and acts as a barrier against the cold.
  
  
• 2). Plug cracks in window frames with putty or another sealing agent.
  
  
• 3). Mount clear plastic tarp over your windows with staples or thumb tacks.
  
  
• 4). Open the windows and drapes to let in the sunshine. Cut down any large branches blocking the sun and put away any awnings installed during the summer for shade.
