As you sleep on the coldest nights of the year, you expect your furnace to keep your home warm and comfortable until morning. But without regular care, your furnace might start to falter, potentially leaving you chilly and disappointed. It’s vital to schedule an annual maintenance check to prevent such unexpected bumps in your comfort zone.
Dirty burners can cause significant problems in your heating system. For instance, turning on your gas furnace doesn’t generate enough heat. These signs should not be ignored; they indicate the need for either cleaning or replacement.
5 Common Symptoms of Dirty Furnace Burners
Below are some of the signs of nasty burners:
1. Flame Issues
First of all, the flame issues can be further divided into two variations such as:
a) Yellow or Irregular Flame Color
When your furnace works correctly, you’ll see a blue flame that signifies a healthy and robust combustion process. If you notice that the flame has turned yellow or orange, this is a classic sign that burners are dirty. This color change is caused by a lack of air from the burners.
Clogging within the system prevents the gas from burning properly. Likewise, the presence of soot and dirt buildup affects heat production.
b) Changes in Flame Behavior
You usually want a consistent and steady pilot light. But if the flame flickers constantly or shifts between colors, it’s a sign that something is wrong. This erratic behavior suggests a problem and points out a serious risk to your home.
Thus, irregular flames and flickering often point to incomplete combustion, which raises the risk of a carbon monoxide leak.
In such cases, call a professional to examine your furnace. They can identify the root of the problem and remedy it.
2. Heating Performance
You may face any of these issues with your furnace:
a) Not Enough Heat
When your furnace starts acting up in the middle of winter, you do not have enough warmth. The insufficient heating you notice or cold spots around your house with inconsistent temperatures.
Once again, the reason can be dirt that clogs the burners. This not only impacts the temperature control on your thermostat but also affects the entire heating system’s efficiency. You must restore your furnace’s ability to produce and distribute warm air throughout your property.
b) Complete Lack of Heat
Secondly, imagine waking up on a frosty morning only to find that your furnace is not producing heat. This total lack of heat can occur when the burners shut down due to buildup.
Sometimes, the unit might still generate heat, but not enough to activate the fan. This is because a sensor inside the combustion chamber doesn’t detect the intended temperature to trigger the blower. Warm air won’t be distributed without the blower, leaving your rooms cold and uncomfortable.
3. Operational Noises
Have you ever heard strange sounds or weird noises coming from your furnace?
If you notice loud sounds like booms, pops, or rattling noises, it’s another common sign. When clogged burners try to ignite, they can cause small explosions. These unusual sounds are common symptoms that indicate that something isn’t right.
I once had an issue where our client’s heating system made these strange noises. This created popping and booming noises and risked severe damage to the heat exchanger. It’s essential to address these issues promptly to avoid costly furnace repairs to your heating unit.
4. Odor Problems
Another most noticeable issue is the unpleasant odor that fills the air whenever you turn on the furnace. It smells like a mix of smoke, rubber, and oil—a telltale sign of dirty burners struggling to function.
Meanwhile, this can cause sooty buildup on the burners. As the furnace continues running, these oily scents spread into your home through the ductwork. These signs can lead to excessive problems like fire or gas leaks. When you notice these odors, make a cleaning appointment for your furnace.
Even if the furnace seems to be working fine, the distinct scent carried by heated air as it flows from the air vents is a clear indicator that something’s off. Cleaning can prevent the flames in the burner assembly from causing further damage to furnace parts so that the unit distributes sufficient heat evenly.
5. Energy Efficiency
When energy bills spike higher than usual, many people are surprised and start searching for the culprit. If you’ve noticed a significant spike in your bill, don’t overlook your furnace burners.
Often, dirty burners are to blame, as they negatively affect your heating system’s ability. The debris buildup around the burners can become so bad that it hampers performance. As a result, the burners consume more energy to compensate for their inefficiencies. Even the system works twice as hard to keep your family warm.
So, you should expect more unit consumption at an alarming rate, leading to shocking utility expenses.
