Common Furnace Problems We Repair in Shreveport
Shreveport furnaces sit idle for much of the year, then work hard during sudden cold snaps in damp air. That pattern wears out specific parts. These are the furnace repairs our technicians make most often:
- Dirty or failed flame sensors: The most common reason a furnace lights and then shuts off. Dust and humidity coat the sensor during the off-season.
- Failed hot surface ignitors: Ignitors crack with age and are a frequent cause of no-heat calls on the first cold morning of the year.
- Pilot and thermocouple problems: On older gas furnaces, a weak thermocouple or dirty pilot keeps the burners from lighting.
- Inducer motor and pressure switch failures: If the inducer motor can’t vent combustion gases or the pressure switch fails, the furnace won’t fire.
- Blower motor and capacitor failures: Worn bearings or a failed capacitor stop warm air from reaching your rooms.
- Limit switch trips: A clogged filter or blocked airflow makes the furnace overheat and shut down.
- Gas valve problems: A faulty valve can keep burners from lighting or cause uneven flames.
- Control board failures: Humidity and power surges from Louisiana storms can damage the furnace’s electronics.
- Clogged condensate drains: High-efficiency furnaces shut down when the condensate line or trap backs up.
- Cracked heat exchangers: A serious safety issue that can let carbon monoxide into your home, and it needs immediate attention.
Whatever is causing your furnace trouble, our Shreveport furnace repair technicians track down the real source of the problem instead of just treating the symptom.

Shreveport Furnace Repair FAQ
Do you offer emergency furnace repair in Shreveport?
Yes. SBC Cooling + Heating offers emergency furnace repair in Shreveport and the surrounding area, day or night. Hive Comfort Club members get priority service and never pay overtime fees.
How much does furnace repair cost in Shreveport?
It depends on the part that failed and the time the repair takes. Flame sensor cleanings and ignitor replacements are usually on the lower end, while blower motors, control boards, and gas valves cost more. You’ll always get upfront pricing before any work begins.
What should I do if my furnace won’t turn on?
Check that the thermostat is set to Heat and above room temperature, replace the thermostat batteries, check the breaker and the furnace power switch, replace a dirty filter, and make sure the furnace door panel is closed. If it still won’t start, the problem may be the ignitor, flame sensor, inducer, or control board, and it’s time to call a technician.
Why does my furnace turn on and then shut off?
A furnace that lights and then shuts off within seconds usually has a dirty or failing flame sensor. If it runs for a few minutes and then shuts down, it may be overheating from a clogged filter or blocked airflow. Both are common in Shreveport because of dust and humidity buildup.
Why is my furnace blowing cold air?
Common causes include burners that aren’t lighting, a furnace that overheats and shuts itself down, a thermostat fan set to “On” instead of “Auto,” a dirty filter, or a failed ignitor or flame sensor.
Why does my furnace short cycle?
Short cycling usually comes from overheating caused by restricted airflow, a dirty flame sensor, a thermostat that’s misreading the room, or a furnace that’s too large for the home. It wears out parts quickly and wastes energy, so it’s worth having it checked.
Why is my furnace running constantly?
A furnace that runs nonstop usually can’t reach the set temperature because of poor airflow, leaky ductwork, a thermostat problem, or a system that’s too small or wearing out. Running constantly strains the blower motor and raises your energy bills.
Can a cracked heat exchanger be repaired?
In most cases, no. A cracked heat exchanger is a serious safety risk because it can let carbon monoxide into your home. Depending on your furnace’s age and warranty, the fix is usually replacing the heat exchanger or replacing the furnace. Our technicians will walk you through both options.
Is it safe to repair my furnace myself?
Homeowners can safely check the thermostat, breaker, filter, and furnace door panel. Anything involving gas components, wiring, ignition, or venting should be handled by a licensed technician. DIY repairs can create carbon monoxide or fire risks and void your warranty.
Should I repair or replace my furnace?
Repair usually makes sense for younger furnaces and one-time problems. Replacement is worth considering if your furnace is 15 or more years old, the repair costs more than half the price of a new furnace, or you’ve needed repairs several winters in a row.
How long does a furnace repair take?
Many furnace repairs, like flame sensors, ignitors, and capacitors, are finished in an hour or two. Larger repairs such as blower motors, inducer motors, or control boards can take a few hours, or longer if a part needs to be ordered.
What should I do if my furnace smells like gas?
Leave your home right away, without turning lights or appliances on or off, and call your gas utility or 911 from outside. Once the gas company says it’s safe, contact us to inspect and repair your furnace.
Why Fast Furnace Repair in Shreveport Matters
A furnace problem rarely fixes itself, and waiting usually turns a small repair into a bigger one. Here’s why it pays to call our Shreveport furnace repair techs at the first sign of trouble:
- Small failures spread: A failing capacitor can burn out a blower motor, and a clogged filter can overheat and crack a heat exchanger.
- Safety risks grow: Venting problems, cracked heat exchangers, and gas valve issues can lead to carbon monoxide exposure.
- Efficiency drops: A furnace that short cycles or runs nonstop wastes fuel and drives up your bills.
- Cold snaps don’t wait: Repairing a problem before a freeze is much easier than an emergency call when temperatures drop into the 20s.
The sooner we can look at your furnace, the more likely the fix is quick and affordable.
Quick Checks Before You Book Furnace Repair in Shreveport
Some furnace problems have simple fixes you can safely check yourself. Before scheduling a repair, try these steps:
- Thermostat: Make sure it’s set to Heat, set above the current room temperature, and has fresh batteries.
- Breaker and furnace switch: Check your electrical panel for a tripped breaker, and make sure the light-switch-style power switch near the furnace is on.
- Air filter: A clogged filter can make the furnace overheat and shut off. Replace it if it’s dirty.
- Furnace door panel: Most furnaces won’t run unless the access panel is fully closed and seated on its safety switch.
- Gas supply: If your other gas appliances aren’t working either, contact your gas utility.
- Vents and returns: Make sure supply vents are open and return grilles aren’t blocked.
If your furnace still won’t heat after these checks, or if the problem involves gas, wiring, or anything inside the furnace, leave it to a licensed furnace repair technician.
Shreveport Furnace Repair vs. Furnace Replacement
Repair is usually the right choice for younger furnaces and one-time problems. Replacement starts to make more sense when one or more of these apply:
- Age: Gas furnaces typically last 15–20 years. If yours is 15 or older, a major repair may not be worth it.
- Cost: If a repair would cost more than about half the price of a new furnace, replacement is usually the better investment.
- The $5,000 rule: Multiply your furnace’s age by the repair cost. If the total is over $5,000, replacement often makes more sense.
- Frequent breakdowns: If you’ve needed repairs several winters in a row, more are likely on the way.
- A cracked heat exchanger: On an older furnace, this usually means replacement is the safest option.
We’ll never push a replacement when a repair will do the job reliably. When replacement is the smarter long-term choice, we’ll explain why and walk you through your options for furnace installation and replacement.
