The contractors we connect you with diagnose igniters, flame sensors, gas valves, pilot lights, pressure switches, and limit-switch short cycling, and they treat any suspected gas leak as an emergency rather than a service call. **If you smell gas right now:** leave the home without touching switches, then call your gas provider or 911 from outside. Do that first. Call us afterward and we’ll connect you with a licensed contractor to inspect the furnace once the property is safe. ![Hot surface igniter and flame sensor inside a gas furnace burner compartment](/images/content/close-up-of-a-hot-surface-igniter-and-flame-sensor.webp) ## Common Problems We Solve ### Furnace won’t ignite The most frequent winter call. A hot surface igniter is a fragile ceramic component that eventually cracks. A flame sensor coated in oxidation stops proving flame, so the gas valve closes a few seconds after ignition, the furnace lights, runs briefly, and shuts off, repeatedly. Both are routine repairs when correctly identified. ### Short cycling and overheating A furnace that starts and stops every few minutes is usually overheating and tripping its high-limit switch. The cause is nearly always restricted airflow: a clogged filter, closed registers, or a blocked return. Beyond the nuisance, repeated overheating is hard on the heat exchanger, which is the part you never want to damage. ### Blower runs, no heat Points at the gas side: valve, igniter, sensor, or the pressure switch that has to prove the inducer is drawing properly before the burners light. Diagnosis follows the ignition sequence step by step to find where it stops. ### Noises and smells A brief dusty smell on the first burn of the season is normal. A persistent burning smell, rumbling, or booming on ignition is not, and a sulfur or rotten-egg odor means gas, evacuate and call your gas provider. ### Suspected carbon monoxide risk If a CO alarm sounds, leave and call 911. A cracked heat exchanger can put combustion gases into your home’s air, and it’s the one fault where replacement rather than repair is usually the honest answer. ## Why Alabama Furnace Calls Cluster Alabama’s heating season is short and sharp. Systems idle through a mild fall, then get asked to run flat out for a week when a cold front pushes down. Dust that settled on burners all summer, a marginal igniter, and a filter nobody changed since June all surface at the same time, and they surface across the whole state on the same night. That’s the practical case for an annual pre-winter check, particularly for a furnace that only runs a few weeks a year, and our seasonal walkthrough on getting your Alabama heating ready before the first cold snap [/blog/get-your-heating-ready-fall-2026-alabama/ →](/blog/get-your-heating-ready-fall-2026-alabama/) covers what to do and when. It’s also why calling early in the day during a cold snap gets you seen sooner: the schedule fills as the temperature drops. ## Repair Costs and Honest Options Igniters, flame sensors, and thermocouples sit at the affordable end of furnace repair. Gas valves, inducer motors, and control boards land in the middle. A cracked heat exchanger typically means replacement, because repairing one safely is rarely practical. These are general market observations, not our prices. The contractor gives you a free, no-obligation estimate for your specific furnace before starting. If you run a dual-fuel system, the heat pump repair [/heat-pump-repair/ →](/heat-pump-repair/) side of the network covers the other half, and the same call reaches both.

Compare Your Options ## Safe Homeowner Checks vs Calls for a Licensed Technician Some furnace problems are worth two minutes of your own time. Others involve gas, combustion, and flue venting, and are firmly technician territory. close Safe to check yourself check\_circle Call a licensed technician Gas smell Nothing. Leave the house without touching switches and call from outside. Always. Call your gas provider or 911 first, then a contractor. Furnace will not start Check the thermostat mode and batteries, the furnace switch, and the breaker. Power is confirmed and it still will not ignite, or it locks out after several tries. Weak airflow Replace a dirty filter and open any closed supply registers. Airflow stays weak with a clean filter, which points at the blower or the ductwork. Short cycling Rule out a clogged filter and blocked returns first. Burners light then shut off while the blower keeps running: that is a high-limit trip from overheating. Igniter and flame sensor Nothing. These sit inside the combustion compartment. Always. Cleaning or replacing them requires opening the burner assembly. Cracked heat exchanger Not homeowner-diagnosable, and carbon monoxide risk is real. Always, and it usually means replacement rather than repair. phone\_in\_talk Call (256) 886-9914 [tel:+12568869914 →](tel:+12568869914) ## Want a straight answer on furnace repair?

From outside, call your gas provider (Spire Energy serves much of Alabama) or call 911. Once the property is confirmed safe, call us and we'll connect you with a licensed contractor to inspect the furnace. Treat every gas smell as an emergency. ### Why won't my furnace ignite? expand\_more The usual causes are a cracked or failed hot surface igniter, a dirty flame sensor that shuts the burner down seconds after ignition, a closed or failed gas valve, or a pressure switch that isn't proving draft. Checking your thermostat, breaker, and filter is safe. Anything involving gas or combustion needs a licensed technician. ### My furnace turns on and off every few minutes. Is that dangerous? expand\_more It shouldn't be ignored. Short cycling usually means the furnace is overheating and tripping the limit switch, often because of a clogged filter or blocked return airflow. It can also be a dirty flame sensor or an oversized furnace. Overheating stresses the heat exchanger, so get it looked at. ### Can I clean the flame sensor myself? expand\_more It's a common homeowner fix online, but it means opening a gas appliance's burner compartment. Given the safety implications and how inexpensive the service call is relative to a gas incident, this is one to leave to a licensed technician. ### How common are furnaces in Alabama? expand\_more Less common than heat pumps, but plenty of homes have gas furnaces, and dual-fuel setups pair a furnace with a heat pump. If you're not sure which you have, the contractor can tell you in a minute on site, or you can check whether there's a gas line running to the indoor unit. ### What's a cracked heat exchanger and why does it matter? expand\_more The heat exchanger separates combustion gases from the air you breathe. A crack can allow carbon monoxide into the home's air supply. It's the one furnace fault where the answer is often replacement rather than repair, and no reputable contractor will keep a cracked exchanger in service. ### How fast can someone come out for no heat? expand\_more Same-day service is available in most covered areas, and the phone is answered 24/7. Alabama cold snaps concentrate furnace calls into a few days, so calling early in the day helps. The contractor will tell you honestly what they can do. ### Should I get my furnace serviced if I barely use it? expand\_more Yes, especially for that reason. A furnace that sits idle for ten months collects dust on the burners and sensor, and seals dry out. An annual pre-winter check is cheap insurance for equipment that only has to work when you really need it. ### Still have a question? Call and describe what your system is doing.
