5 Signs Your Furnace is Breaking

Furnace6It’s starting to get a little chilly here in North Carolina. You’ve probably switched your thermostat from cooling to heating mode. You may even have a nice quilt on the bed to keep you warm. A few extra blankets won’t do much for you if your furnace breaks. It’s best to prepare so that you’re not left out in the cold. Here are a few sure signs your furnace is on its last leg.


Depending on what you have and who you ask, the average life expectancy of a furnace is between 10-20 years. Of course, performing regular maintenance will help you get the most out of it. Just like a car, it won’t last nearly as long if you don’t take care of it and clean it periodically. When was the last time you had your furnace cleaned? If you can’t remember, it’s been too long.

Rising Power Bills or Uneven Temperatures

Furnaces become less efficient over time. Older furnaces may take longer to produce the same amount of heat that they did new. Take a look at your energy bill. Is it more expensive than it was last year at this time? If so, it may be worth considering a new furnace.

Furnaces that are older or are breaking down may also have trouble distributing heat evenly throughout your home. Start by trying to determine the cause and fix the problem on your own. If that doesn’t work, your furnace might need to be replaced.

Constant Repairs

Think about the last time you bought a new car. Maybe you just wanted something new, but people often buy new cars because it’s too expensive to fix the old one. If it’s costing more to fix it than it’s worth, it’s time to visit the dealership. The same goes for furnaces. Over time, the small parts inside a furnace wear out. If you have to call professionals to your home for repairs more than once in a year, consider it a sign that repair costs are going to continue to rise. If you’re going to have to put money toward your furnace anyway, it might as well be a brand new one.

Strange Noises

Odd noises from any type of electronic device or machinery are usually a bad sign. For furnaces, keep an ear out for popping, rattling, grinding, or squealing noises. In some cases, these sounds can be fixed with a simple repair. Schedule a maintenance check so that professionals can determine the cause of the noise. If they can’t fix it, your furnace may have major issues.

Poor Air Quality

If your furnace isn’t working properly, it might not be filtering air properly. Air will feel more dry and dusty. If you or your family members have asthma or allergies, you may notice an increase in breathing issues from additional pollen and allergens in the air.

Burning in the nose or eyes, nausea, disorientation, or flu-like symptoms could mean that the problem is much more serious. A cracked heat exchanger can lead to carbon monoxide leaks. These leaks are extremely dangerous to you and your family. If you’ve noticed any of the symptoms mentioned, take a look at the flame coming from your burner. It should be steady and blue in color. If it’s yellow and flickering, there may be a leak. In this case, stay someplace else until you can determine whether or not you are being exposed to carbon monoxide. Schedule an appointment immediately to determine the cause.
