Symptoms That Your Furnace Is Having Problems

Before suffering a complete furnace break down, there are normally tell tale signs that something isn't right. This may go on for some time before your furnace fails. In most cases, the signs you need to call a Franklin HVAC contractor may go unnoticed unless you know what to look for. Since it's always best to catch problems early before they become bigger and more costly, be aware of these symptoms which often signal furnace trouble:

  • Odd Smells: This does not include the musty odor you get when you first turn your furnace on for the season—the smell of dust burning off that settled in the off-season. Other than that, if, you notice a persistent or sudden smell, you'll want to call a Franklin HVAC professional.
  • Strange Noises: Your furnace should not be making clanking or banging noises. If it does, your unit likely has developed one of several possible issues. A heating repair expert can determine the cause. Call (317) 714-0936 and we can schedule a furnace repair in Franklin and Greenwood .
  • Frequent Service Calls: There's not a furnace in the Greenwood or Franklin area that won't at some time need service due to a failing part. Twenty five percent of all homes in the US call an HVAC technician each year for other than preventative furnace maintenance visits. Repeated issues in a heating season suggest your furnace is nearing the end of its life.
  • Increasing Utility Bills: Your electric and gas bills can go up for several reasons, cooler temperatures being the most obvious. Yet, unexplainable increases in energy bills might warrant having our Franklin HVAC experts look at your furnace. Often a furnace that's being pushed past its limit will consume more energy.
  • Surface Rust: Small amounts of rust can often be found on older units, however, large amounts—especially on the flue—point to venting that is not functioning properly. If the source of the rust is a roof or plumbing leak, the resulting rust can be dangerous if it reaches the heat exchanger allowing deadly carbon monoxide to seep into your home. Don't take changes—give Johnson Heating, Cooling, and Plumbing a call if you see significant rust on your furnace.
  • Frequent Cycling: A furnace should not be constantly turning on and off. If yours is, it's likely something is not right. Your furnace may be too large for the size of your house, or it could be something else. This kind of problem can have several causes and be difficult to diagnose. Count on our Franklin heating repair experts to figure it out and fix it quickly.
  • Start-Up Issues: If dropping below the set temperature on your thermostat does not cause your furnace to turn on or you hear clicking noises at start up, your furnace needs to be checked. Often, these signs precede a furnace breakdown. If you find this happening, submit a schedule request or give Johnson Heating, Cooling, and Plumbing a call at (317) 714-0936.

The good news is that, Johnson Heating, Cooling, and Plumbing can handle your furnace repair whatever the cause. While most of our service calls are to homes in Columbus, Greenwood, and Franklin, residents in the surrounding areas know and trust us, too.

The Top 5 Causes of Furnace Failure

It’s important that homeowners understand what parts of their furnace are most likely to fail. This can better prepare them to communicate with us about their heating problems. It also allows us to quickly fulfill your heating repair needs in Franklin and Surrounding Areas. When fixing heating systems in Franklin, we often find the following culprits, some of which can save you a service call:

  1. Clogged Filters: When was the last time you swapped out your furnace filter? If the answer is more than a few weeks ago, it might be time to check it, especially if you have pets. When running, your heating system pulls in dust, dander, and dirt. This is kept out of the mechanical parts by your furnace filter. A clogged filter restricts airflow, making your heating system work harder. Replacing it not only helps efficiency, but also improves air quality.
  2. Bad Thermostats: Your thermostat is responsible for signaling your furnace when to turn off and on to maintain the set temperature. If it’s not working properly, you’ll struggle to get warm. For instances where the thermostat may be at fault, make sure its batteries are good, if it uses any. Also, double-check that it is set to HEAT with the run method on AUTO.
  3. Ignition Failure: Sometimes the pilot light or surface ignitor will fail and refuse to light the burners. If this happens your furnace won’t be able to heat the air, leaving you in the cold. To prevent this, have it checked and cleaned regularly by our Franklin-area HVAC professionals. If it's the middle of winter, though, just give our Franklin HVAC contractors a call at (317) 714-0936 instead.
  4. Exhaust Blower Issues: The furnace exhaust blower is what takes the combustion gases out of the heat exchanger and vents it safely outdoors. If this component fails, the furnace will cycle on and off or shut down. Regular inspections and maintenance visits can prevent this from happening.
  5. Blower Motor Failure: The blower motor is essentially what keeps the air moving around your home. Should this component fail, it doesn’t matter how efficient your furnace is, the hot air won’t be distributed around your home. The blower can fail from overheating or from it becoming clogged with debris. Have your ducts cleaned and your furnace tuned up to keep the blower working effectively.
  6. Bad Heat Exchanger: The heat exchanger is one of the most important components of a conventional furnace. It is the component that safely transfers heat from the flame into heated air that is circulated in the home. When the heat exchanger develops holes or cracks, replacing it can be quite expensive. Some people prefer to simply replace their furnace. An expert evaluating your system can best advise you. If the stress on your heat exchanger is due to excess cycling due to having too large of a furnace, only replacing the heat exchanger will result in the same problem developing again.

Frequently Asked Furnace Repair Questions

Why Isn’t My Furnace Reaching the Temperature I Set?

  • Problems with the pilot light or flame sensor

For expert help, contact Johnson today.

When your furnace in Franklin blows cold air, it might be due to something simple or more complex. Start by checking your thermostat to ensure it’s set to heat.

If these steps don’t solve the problem, call Johnson for professional assistance.

  • Dirty burners causing booming sounds
  • Cracked heat exchangers making popping noises

Ignoring these noises could lead to further damage. Contact (317) 714-0936 to schedule a repair.

Water leaking from a furnace might seem odd, but newer high-efficiency systems often create condensation. Common causes include:

  • Faulty condensate pumps
  • Air conditioner or humidifier issues

Leaking water can damage your furnace, so call (317) 714-0936 to address the problem right away.

Older furnaces in Franklin may have a standing pilot light that occasionally goes out. To safely relight it:

  1. Turn off the gas and wait five minutes.
  2. Adjust the gas valve to “Pilot” and press the reset button.
  3. Use a long lighter to ignite the flame.
  4. Once the light is steady, release the button and turn the valve to “On.”

If it doesn’t stay lit, contact Johnson for assistance.

A cracked heat exchanger is a serious safety issue for furnaces in Franklin. It can cause incomplete combustion, allowing carbon monoxide—a deadly gas—to leak into your home. Replacing a heat exchanger is costly, so it’s often more economical to replace the entire furnace. Our experts can assess the best option for your home.

If your furnace seems to be running endlessly, it’s likely due to a thermostat malfunction, clogged air filters, dirty flame sensors, or an obstructed flue. These issues waste energy and can overheat your system. Call (317) 714-0936 for fast diagnosis and repair.

If you’re uncomfortable doing this, call Johnson for help.
