Heating Your Maryland Home: Warning Signs Your Furnace Needs to Be Replaced

No one wants a dead furnace during freezing temperatures. Your gas furnace will tell you when it needs to be replaced; if you pay attention, you’ll have heating in your Maryland home when you need it.

Here are some warning signs that your gas furnace may need to be replaced:

Your furnace is getting old. The average life expectancy of furnaces in homes today is between 16 and 20 years. If your furnace is close to this age or older, you should begin shopping. You don’t want to be shopping for a replacement furnace during an emergency. Not sure how old your furnace is - check your furnace to see if you have a pilot light. If you have a pilot light, your furnace is over 25 years old.

Your gas & electric bills are going up. Rising gas and electric prices are not the only reason for high bills. Furnaces often lose their efficiency as they age especially if they have not been properly maintained. As a result your furnace may run longer to provide the same amount of heat. This will cause your gas & electric bills to go up. The money you pay the gas & electric company every month could be used to pay for new furnace.

You’ve had expensive furnace repairs in the last 2 years. As your furnace ages, you’ll start having to replace parts, and eventually you’re spending $500 or more a year just to keep your old furnace going. Furnaces incur the most breakdowns in the last 2 years of their lives.

The thermostat doesn’t seem to be working right. Are some rooms too cold, while others are too hot? Always fiddling with the thermostat to make your home more comfortable? This is a sign that your furnace lacks the ability to properly distribute the air in your home.

Your furnace is making strange noises. Have you heard any banging, popping, rattling, or squealing noises coming from your furnace? Old furnaces often start to make some strange noises as they get toward the end of their life. Or have you heard the furnace blower running excessively, or turning off and on repeatedly?

Your burner flame is yellow instead of blue. This is a bad sign - a yellow or flickering flame may indicate that poisonous carbon monoxide could be created by your furnace.

You and your family have been feeling ill with headaches and nausea.
Furnaces as they age run the risk of developing cracks in the heat exchanger inside your furnace. Carbon monoxide, if present, could leak into your home undetected. Signs of this may be frequent headaches, a burning feeling in nose or eyes, nausea, disorientation, and flu-like symptoms. Should you experience any of these, air out your house, open a window to the furnace room and immediately call 911 and a gas service technician.
