A Nightmare Before Christmas – 7 Warning Signs
Posted By: 
Tuesday, November 14, 2017

It’s a horrible feeling. You get out of bed to get ready for all the guests arriving in a few hours. You expect a warm and toasty room, but before your feet hit the floor, you know something’s off and it appears to be the furnace. No matter how high you turn the thermostat, the heat is gone. As you pick up the phone to call for help, you wonder if there were any warning signs. Could you have avoided disaster?

1.      Did you hear any rattling, rocking, or vibrating noises? These could indicate something as mild as a loose panel or something as serious as a cracked heat exchanger.

2.      What about a low rumbling sound? In oil-burning furnaces, this might mean oil is inside the combustion chamber.

3.      Did you see a flickering or yellow pilot light? This is a sign of too much carbon dioxide around a gas-burning furnace. Try adjusting the burner light screw to get the light blue again. If this fails, it’s time for maintenance or replacement.

4.      Have you heard a scraping sound? This means the ball bearings are worn out. Shut off the system and call a service technician right away.

5.      Any high-pitched squealing? This can happen when the belt is slipping or the ball bearings need lubrication.

6.      Have you had difficulty keeping the entire house equally warm? This might indicate that the furnace needs a tune-up.

7.      Are the houseplants drooping (and not from lack of water)? Are members of the household suffering with dry skin or noses, or scratchy throats? Is there static electricity? These are all signs that the furnace needs maintenance. If it’s in good working order, it keeps the air clean and provides comfortable humidity levels.

But this was just a nightmare. You wake up to find your furnace is working just fine. Why? Because you know the warning signs and you know who to call for repairs and maintenance.
