Please read my Disclosure and Privacy policies hereWhen you have a furnace to take care of, you probably don’t even think about its needs until it’s not working right. This is the worst time to remember that you have a furnace that you haven’t taken care of recently.
You need to know what the early warning signs of a furnace that needs servicing are so that you can avoid this unfortunate experience.
A furnace repair contractor can help you take care of your furnace before it breaks entirely. You should have someone come to take a look at your HVAC system and your furnace, specifically, at least once a year to make sure that you don’t have any unwanted surprises when you need to keep your house warm during the coldest part of the year.

Early Warning Signs that You May Need Furnace Maintenance
Knowing that there is something wrong with your furnace can help you avoid a major repair bill as well as some risky problems that could lead to health risks for your family.
You should consider having someone look at your HVAC system each year to avoid issues related to furnace performance before the cold weather hits each year.
1. Unusual Noises
Banging, rattling, squealing, or grinding noises can all indicate that your furnace has loose parts, a failing motor, or other issues. This is something that you might not hear unless you stand near your furnace when it is cycling on and off.
If you haven’t had your furnace checked out recently, you need to take the time to listen to it cycling on and off a few times to verify that it is not making any suspicious noises.
2. Strange Smells
If you have a musty smell circulating through your home, this could indicate dust and mold, but it could also indicate that there are electrical issues within your furnace and its connections. Some people will report a rotten egg or gas smell as well.
You should immediately shut down your system if you smell rotten eggs or a gas smell, as this could indicate dangerous problems that need immediate attention.
3. Poor Airflow Throughout Your Home
If your furnace is not pushing much air through the vents, you should consider getting someone out to take a look at your furnace right away. This could be due to something as simple as a dirty filter, but a blower issue is more likely.
Without a good-quality, fully operational blower, your furnace will work far too hard and could eventually fail. You will also struggle with cold and hot spots throughout your home while the blower isn’t working.
4. Increased Energy Bills
A common warning sign that your furnace isn’t working well is that your energy bill is increasing. The system is likely working hard, which can lead to a breakdown as well as those painfully high bills. You should consider a sudden spike in energy bills as a key warning indicator that there is something wrong.

5. Short Cycling
Short cycling can be hard to catch if you don’t pay much attention to your furnace and how it’s operating. When the furnace is short-cycling, it’s often because of a dirty flame sensor, but there are other reasons that you might experience this symptom.
Your thermostat might also be to blame for this kind of problem. Having someone diagnose this problem correctly is key.
6. Startup Issues
Hesitation at startup, multiple restarts, or even failure to ignite can all be linked to wiring problems, but there are lots of potential culprits for these problems. This is another issue that can slip by you if you are not able to hear your furnace starting up due to its location.
Just like short cycling and other symptoms that often slip by homeowners, startup issues can be hard for homeowners to diagnose early.
7. Yellow Pilot Light
A yellow pilot light is not normal. A blue flame is normal. When you see a yellow flame, this is often because of incomplete combustion. This is a serious carbon monoxide risk and deserves immediate attention.
If you are not comfortable checking on this part of your furnace’s behavior, you can have a skilled technician come and take a look.
Furnace Maintenance can save you money and can also help you to heat your home efficiently. You shouldn’t have to struggle with increased heating costs and hot and cold spots throughout your home. If you are noticing any of these symptoms, you should call a technician to come and take a look at your furnace.
Make the time to check on the health of your furnace well before the coldest part of the year hits. It can be hard to fix your furnace when the weather is really harsh, and the increased cold can take a toll on a system that is not performing well already.
Don’t wait until it’s too late to do a simple repair, and make sure that you are paying attention to your heating and cooling system periodically.
Knowing the Warning Signs of a Furnace Issue is Important
Being a homeowner means having to pay attention to a variety of different issues that could crop up each year. You need to be sure that you are familiar with the things that could happen that might impact your home’s comfort, safety, and affordability.
Taking care of your furnace is important. If you are not familiar with the needs of your HVAC system, that’s totally fine. You can have a skilled technician come and check on your furnace’s function at least once a year. Always be sure to schedule this appointment before the coldest part of the year.
Your furnace has a lot to do with your comfort, the air quality in your home, and your savings when it comes to energy costs. You need to take care of it properly to be sure that you don’t run into major, costly issues that could have been avoided with ease.
